Using the Microsoft Baseline Security Analyzer – Part 4 of 5 in Troubleshooting for Windows Vista

April 13th, 2010

Another excellent tool that’s freely available to Windows Vista administrators (or anyone else, for that matter) is the Microsoft Baseline Security Analyzer (MBSA). This tool scans a system and quickly identifies security holes such as missing software patches or accounts with a blank or weak password.

Better yet, it recommends corrective action. The only bad news of sorts is that it’s not built into Windows Vista. You have to download this one from the Microsoft web site. The newest version of this tool at the time of this writing was released in May of 2008, Version 2.1. This updated version provides additional features which are detailed at the Microsoft website.

However, legacy Microsoft products are not supported by MBSA 2.1. Because of this, Microsoft has teamed-up with Shavlik Technologies to offer a free companion tool for MBSA 2.1. This will allow users of MBSA 2.01 to still receive security updates.

For the MBSA 2.01, the install steps are straightforward; just follow the steps in the wizard. During installation, the MBSA places a shortcut on the desktop by default. To launch the tool and perform a scan, follow these steps:

Double-click the desktop icon, and then, from the MBSA home page, choose Scan a Computer. Note here that admins can also use the MBSA to scan multiple computers in a network from a central location. In the Computer to Scan page, you should see the local machine listed if you’ve chosen the “Scan a computer” option. (The other selection produces a page from which you can select a range of machines.) Furthermore, the options in this screen let you specify exactly what components get checked during the scan. Once you verify the machine to scan, click the “Start scan” link. You’ll now see a Scanning page with a progress bar that can take several minutes to complete. When the scan finishes, you’ll see a report screen.

As you can see, this provides extremely valuable information to administrators who are interested in doing everything they can to stop problems before they start. For example, the administrator of this machine has been very diligent about installing necessary software updates, it seems, and has gotten passing grades in most areas of computer security. But the MBSA scan generates a failing grade…how is this possible? The MBSA makes it easy to investigate the exact nature of the failing grade by clicking the “Result details” link, revealing the dialog box. In this case it reveales a very significant (yet usually hidden) threat: local user account passwords are weak, thus generating the failing grade.

Automatic Problem Resolution – Part 3 of 5 in Troubleshooting Essentials for Windows Vista

April 11th, 2010

Each time you encounter a significant error using Windows Vista, you’ll be asked whether you want to send the information to Microsoft. You might think this is just a one-way street, where you’re providing information that will help Microsoft write software in the future that will prevent whatever problem you’re having.

If you think about it for a moment, that must be one huge store of information being generated by the planet’s users of Windows computers. So, why should one entity be the only beneficiary? Surely there must be a way for ordinary users to leverage this information as well, right? Surely some other user in another corner of the computing globe is – or has had – the same difficulty as you. Right? The answer is yes, and yes. Users can use the information gathered from other users to try to troubleshoot issues, using a utility called Problem Reports and Solutions. If there’s a known solution to a known problem, you can use Problem Reports and Solutions to easily retrieve the fix. Here’s how to put it all to work:

Open the Control Panel, and then open Problem Reports and Solutions. As always, you can type problem from the Start menu. You’ll see the Problem Reports and Solutions window. In this window are several tasks on the left pane and a status area on the right. To see a list of problems that Vista has detected, click the View Problem History link. You’ll see a dialog box. You can view further details about each problem using the links herein. After visiting the Problem History page, you can run a check for solutions by navigating back to the Problem Reports and Solutions home page and clicking the Check Now button. Vista then checks online for any available solutions. If it finds one, you’ll see a dialog box. From there, simply follow the “Solution found” link for instructions on how to resolve the detected issue. Most times, it will involve a software download and install.

Note that much of this problem-checking behavior is completely automated by default. Administrators can govern this, however, by following the “Change settings” link on the left. After clicking this link, you will be able to toggle automatic reporting either on or off, and you will be able to configure a few other options.

Administrators can set exceptions if they have a program that they want Vista to ignore when it reports a problem. It should also be noted here that one user’s setting doesn’t necessarily have to be the setting for other users. If you’re changing the reporting settings for all users, you will be asked for administrative confirmation if User Account Control is turned on.

If you’d like to get my entire book “Windows Vista Administration: The Definitive Guide” by Brian Culp, Publisher: O’Reilly, ISBN-13: 978-0-59-652959-8 (or any of my 20+ other books and tutorials), you can pick it up at my website, www.TheAnswerHub.com or at most major book chains.

Automatically Updating Vista – Part 2 of 5 – Troubleshooting for Windows Vista

April 11th, 2010

You should probably view Vista’s Automatic Updates the same way you view a yearly physical checkup. It’s just something that you should do to prevent as many issues as possible before they become issues in the first place. The Windows Update engine handles two kinds of updates:

Critical updates: Can help speed up your system, secure it, and keep it from crashing Recommended updates: Will address noncritical problems and help enhance your computing experience

A third kind of update, the optional update, is not downloaded automatically. You must get these updates manually by running the “Check for updates” task in the Windows Update Control Panel application.

By default, Windows Updates turns on the Automatic Updates feature, so it’s very likely that this is something you’ll never have to do in your administrative career. It’s still a good idea to know where to look, though. Here’s what to do:

Open the Windows Update Control Panel application by typing update at the Start menu. It’s under the System and Maintenance grouping if you’re going through the Control Panel. In the list of tasks on the left, click “Change settings.” From the dialog box, choose the desired update options. Click OK to commit your changes. You may be asked for administrative confirmation by User Account Control.

Additionally, if the Automatic Updates feature is ever turned off, the Vista Security Center will yell at you (assuming that the Security Center notifications about Automatic Updates defaults haven’t been changed). Once you’re in the Security Center, you’ll see a “Change settings” button, that will take you right back to the Automatic Updates settings dialog box.

The Windows Updates are applied to the computer, and therefore affect all users of a particular system.

Sometimes during troubleshooting, you will want to double-check to confirm that a particular update has been installed. If this is the case, you can choose the “View update history” link on the right side of the Windows Updates dialog box.

Troubleshooting Microsoft Windows Vista (5 Part Series) – Introduction

April 8th, 2010

Computer troubleshooting is in many ways more art than science; it’s more of a marriage between your basic computer understanding and all the peculiarities of your specific environment. Truth be told, this series of articles actually possesses very little capability in terms of helping you troubleshoot your network. What it can do, however, is get you pointed in the right direction so that you have a better idea of the troubleshooting resources that are at your fingertips within Vista.

Of course, there’s no way any computer article can possibly foresee every possible computer troubleshooting scenario. If you want to really know whether a particular troubleshooting approach will work, my best advice is to give it a try. It’s just a machine, after all, and you aren’t going to break it with a few clicks of the mouse.

OK, you might break it, but if you follow some of the advice laid out in this article, you shouldn’t be able to do anything that you can’t undo. Here, we focus mainly on some of the troubleshooting tools that Windows Vista places in the hands of the administrator. As always, the focus is mainly on what’s new: we will examine a new utility called Problem Reports and Solutions, and I’ll bet you don’t need to read much further to guess what the nature of that one is. Also, we’ll explore some tools that an administrator might already know from previous operating systems like the System Restore utility, and we’ll look at situations in which System Restore just might save the day.

In this 5-part series of articles, we will discuss the various tools available for troubleshooting within Windows Vista. As I’m sure you’re aware, this is just the tip of the proverbial iceberg. If you’d like to get my entire book “Windows Vista Administration: The Definitive Guide” by Brian Culp, Publisher: O’Reilly, ISBN-13: 978-0-59-652959-8 (or any of my 20+ other books and tutorials), you can pick it up at my website, www.TheAnswerHub.com or at most major book chains.

Visit me at my website and submit your questions to me. I’ll get back to you with an answer as soon as possible.

Up next: we start with a look at a troubleshooting task that is meant to prevent many problems from happening in the first place. It’s the Vista Automatic Updates, which Vista admins should absolutely use to enforce good preventive health.

Google AdWords Strategy – Part 3: Other Google AdWords Strategies

April 3rd, 2010

3. Other Google AdWords Strategies

     Google AdWords Ad Positioning

    Although the profit margin on the product or service offered is a large factor, tests have proved that the first ad position on the first page is, generally, not the most profitable. Yes, it gets the most clicks, but it’s often a spontaneous action by the surfer before studying the ad. Sometimes the surfer is merely browsing the subject and is not ready to buy (commonly known as “tyre-kickers”).

    Tests show that the further down the page an ad is, or, occasionally, even on the second page, the greater is its conversion rate. The surfer has taken the time to read the ad carefully because he is ready to buy. Furthermore, the clicks are fewer; so, your overall pay-per-click bill is less than for a higher-positioned ad. The downside is that the click-through rate (CTR) of the lower-positioned ads is lower, which affects your Quality Score adversely and raises your cost per click.

    A happy medium is to aim for positions 4 to 6 on Google’s first page. (You can use the “Show Estimated Ad Position” and “Estimated Avg CPC” columns in the on-line Google AdWords Keyword Tool to determine the cost-per-click to bid for each of of your exact match keyword phrases, and then you can set those bids accordingly. These figures can, however, be notoriously inaccurate. Always check your keyword phrases’ positions afterwards in the ‘Avg Pos’ column on the Ad Group’s ‘Keywords’ index tab or by testing with a search on the main keyword phrases.)

    “Google Search” ads, “Content Network” ads, “Search Network”/”Search Partners” ads, “Placement” ads

    You can specify different maximum bid amounts for these various types of advertising. Because the quality of their traffic tends to be lower, bids for the Content Network (“entire network” option) and Search Network (Search Partners) (see Tactics > Search Network) should be kept lower and be more tightly controlled than those for Google Search traffic and the Content Network (“Placement ads” option). In the early stages of a new Google AdWords campaign, it is advisable to go with only Google Search traffic and switch other options off, to help you to control costs. Once you’ve discovered the keywords that produce the highest return on investment (ROI), you can enable other options for those keywords to see what results they produce.

    If you find that a Google Search traffic campaign is too competitive, don’t just abandon Google AdWords altogether; try a Content Network Placement ad (see Tactics > Placement Ads), bidding either CPC or CPM (q.v.).

    Testing and Tracking

    Ad Variations

    Despite what you may think of your copywriting prowess, you will not write the perfect ad at the first attempt. You may need ten attempts before you find the best formula. Although you may hazard a reasonable guess at the advertisement text that would attract visitors, the ONLY way to KNOW what ad text achieves the highest click-through rate (CTR) is split-test two ads simultaneously.

    Although changing just a single word can make a difference, do not split-test two ads that resemble each other that closely; Split-test two radically different ads. (Switch off Google’s option to show the better-performing ad more often than the other, as that would distort the test results.) After between 20 and 50 clicks it should become apparent which of the two ads is out-performing the other. Then replace the inferior ad with another and split-test again. Repeat this process again and again, each time reducing the textual differences between the two ads until you arrive at the one that performs best of all.

    To track the click-through rate (CTR) of your ads, go to your Google AdWords campaign web page, click on the Campaign name; click on the Ad Group name; click the ‘Ad Variations’ index tab; check the ‘CTR’ column.

    Always keep all the Ad Variations that you create, to check that you don’t repeat any inadvertently.

    Landing Pages

    Split-test your landing pages in a similar way, to discover which style, layout, text, call to action, etc. achieves the highest conversion rate. To track the conversion rates of your web pages for various keywords, go to your Google AdWords campaign web page and click on the ‘Conversion Tracking’ item on the ‘Campaign Management’ index tab.

    Always save all the landing pages that you create, to check that you don’t repeat any inadvertently.

    Keywords

    After a new campaign has been running for about a month, check the click-through rate (CTR) of all the keyword phrases in each Ad Group on its ‘Keywords’ index tab. Click the ‘CTR’ column header to sort the keyword phrases, mark the checkbox of all keyword phrases with a CTR of less than 0.5% and either ‘Pause’ or ‘Delete’ them. (If you have many keywords, it’d probably be quicker to do this in your specialist AdWords software tool and upload the keyword list to your Google AdWords campaign again.)

    0.5% is considered the benchmark of a poorly performing keyword. Such keywords cause your ad to be displayed but, for some reason, the people using the keyword in their search terms don’t connect it mentally with your ad, and don’t click on it. If several keywords have a low click-through rate (CTR), the overall click-through rate (CTR) of your whole Ad Group is reduced and its Quality Score will be affected adversely. Eventually, this Ad Group’s lower Quality Score will also affect the Quality Score of your entire Google AdWords campaign.

    This check should be performed weekly thereafter.

    If you really want to use those poorly performing keywords, remove them from the Ad Group and create a new Ad Group for them, or even a new campaign, so that they don’t affect your overall Quality Score.

    The Bottom Line

    Great importance is attached to the click-through rate (CTR), but, to put it in perspective, it is only a means to an end. A high click-through rate (CTR) does not make you a millionaire in itself; It’s revenue that counts. Your revenue is determined by the successful interaction between keywords, Ad Variation and landing page, all three working in harmony together.

    Maximum CPC Bid

    Don’t be afraid to bid higher than necessary for keywords in a new Google AdWords campaign during the first few days. This will establish your campaign with Google and, as your click-through rate (CTR) rises, your maximum CPC bid amount to achieve the same ad position will fall dramatically. Then you lower your bids and check again the next day. Repeat this process until your bids are minimized. You do this for all the keyword phrases in the Ad Group. If there are too many keywords to deal with manually, invest in specialist software to calculate the bids for you.

      CPC or CPM?

     Google ‘Content Network’ advertising (see Tactics > Content Network) gives you the option to specify your keywords’ maximum bids as cost-per-click (CPC) or cost-per-thousand-impressions (CPM) (“M” is the Roman numeral for 1,000, “mille” in Latin). CPM can be useful if the Quality Score is low or the cost per click (CPC) is high. If you opt to pay for impressions rather than for clicks, Google couldn’t care less about Quality Score or click-through rate (CTR) or even relevance; You simply pay each time your ad appears. Of course, it’s still in your interest to ensure that you follow the advice about relevance already given.

    It’s your responsibility to track the performance of your CPM ads, because Google doesn’t do it for you. Obviously, you won’t want to keep paying for ads that don’t convert. Moreover, you’ll still have to bid high enough to get your ad to be displayed in the desired position within an ad unit on an AdSense publisher’s web page, or even at all, and that cost could be quite high on a good-quality, popular web site that you choose for a ‘Placement’ ad (see Tactics > Placement Ads).

     Keywords

    Unless you have a six-figure annual budget and would be happy with a mere 10% return on investment (ROI), don’t bother bidding for popular 1-word keywords, such as “mortgage”. The competition for most single-word keywords is fierce, unless the niche is very esoteric. Moreover, searches on single words are made most frequently by people who are simply not ready to spend their money; they are merely investigating the market, gathering information; in other words, they are “tyre-kickers”. 1-word keywords would probably bankrupt you very quickly.

    2-word keywords are a better bet, but they can still command a high cost per click in competitive markets, surfers who search on them may still not be ready to buy, although they’re getting there.

    Keyword phrases of three words and up are known as “long-tail” keywords. (Note that the word “keyword” in pay-per-click advertising can mean a phrase of more than one actual word, e.g., “New York”. A “keyword phrase” consists of more than one “keyword”.)

    3-word keyword phrases have the highest conversion rate, according to tests. People who type three words as a search term have usually done their investigations, know exactly what they want, and are now ready to buy.

    4-word keyword phrases fare slightly less well, perhaps because the searcher may indeed be ready to buy, but is comparing prices for a very specific item, or is doing some academic research.

    Don’t understimate the power of negative keywords! If you sell tulips, you don’t want your ad to appear when someone searches on the term “grow tulips”. Although they may not click on your ad, it’d be an unnecessary impression, and its click-through rate (CTR) would suffer. Specify “grow” as a negative keyword. (Of course, if your Ad Group contains only exact match keyword phrases, there’s no point in specifying negative keywords.)

     Landing Page

    Relevance is covered above, and is by far the most important attribute of a landing page. Here is some advice about other ways to encourage Google to enhance your Ad Group’s Quality Score.

    Google values “real” web sites more highly than mere single-page “mini-sites”. The robot checks for links to other web pages, particularly a ‘site map’ page and ‘privacy policy’ and ‘contact us’ pages. A ‘terms of use’ and an ‘about us’ page may also help. Hyphenate these page names as the file names, e.g., ‘privacy-policy.html’. Place the links to these pages at the very bottom of your landing page, in the footer, using as small a font as a human would consider reasonable. You want to reduce the risk as much as possible that your visitor will click away from your landing page.

    Minimize the landing page’s load time. It is believed that Google uses this as an element in its Quality Score algorithm. Keep images and JavaScript to a minimum. They weigh the page down. (Google cannot follow JavaScript links anyway.)

     How to Attract Visitors

    What makes a person click on your ad instead of someone else’s? The answer is the same as to the question why a person clicks the ‘Buy’ button on your sales page: good copywriting. That’s a separate subject, but, suffice it to say here that your ad must be not only relevant, but also compelling. Imagine that you are the searcher, looking to buy a product or service like yours. Look at other ads offering something similar. What attracts you to one and not another? Ask your friends and colleagues what they think.

    You have only a 25-character headline and two description lines of 35 characters each. Don’t squander them on waffling about your company. The consumer couldn’t care less about you or your company. The consumer has a problem to be solved, a need to be satisfied, a desire to be fulfilled. So, mention the problem, the need, the desire. And, most important, tell the consumer that the solution, what he needs, what he wants is only a click away. Tell him to “Get Help Now” or to “Find It Here”. That’s the ‘call to action’.
