mup.sys boot hang on windows
Hung at mup.sys is a fairly common error on a Windows 2000, XP, or Vista system. If you scan the net for solutions for a mup.sys boot hang on windows you will find that there a many different resolutions recommended to solve this apparently confusing boot issue.

The truth is, this hang is not normally caused by the mup.sys driver itself. In fact, you can use the windows xp recovery console to disable loading mup.sys at startup and you will see the hang will then occur at the driver that had loaded previously to mup.sys. The real cause of this boot hang actually occurs during the windows boot process that follows after loading mup.sys.

What is happening during this boot process? Well after mup.sys loads windows starts configuring itself to the hardware specific to your system. It refers to ESCD data, PNP information and its registry. If there are problems processing that data you will get the described lockup or in some cases go into a reboot loop. Alas, there are even some more causes that get the best troubleshooters scratching their heads! Find the resolution here.

We have an updated tips and troubleshooting guide that will help you get to the root of this nasty boot hang issue and resolve it fast. As an added bonus we provide a unique, easy to understand description as to what actually mup.sys does from windows  programmer resources. 
Jump to Resolve mup.sys boot hangs on windows to get the full story.

Any questions, kudos, opinions, success stories or whatever?, Please feel free to leave a comment or two.
I'd really appreciate that!

Good luck and best to you! Thanks for stopping by.

How to resolve RewriteLog issue - Not logging processed redirects
RewriteLog issues? See Working with Apache Redirection - Help! RewriteLog not logging rewrite data.
 
We recently ran into this issue with a customer that had a WAMP server that was encountering mod_rewrite logging issues when using mod_rewrite directives in the directory definition context (non-.htaccess) for a virtual host. I Google'd and couldn't find any quick answers. Well, I worked it out and here is the fix.

Click on the link above to jump to the article and find out all the gory details needed to make it work!

In all honestly it wasn't that bad. Check and see!

Enjoy!

Updated mod rewrite on Apache Redirection Page
We have just updated the Working with Apache Redirection page to include more working examples using mod rewrite. The "how it works" details have also been expanded so the viewer can better learn from the examples and be better prepared to modify the examples to suit their needs.
 
We also added an example showing how to get a server error 500 and details on why it happened, also in keeping the users interests in mind. 

One common question I get is "How do I redirect from a non www URL to a www URL? When I searched the web I found numerous examples but with little explanation as to how they worked. When I tested the various versions I got... well, various results. Some of them unpleasant!

Most just plain didn't work or work in all situations.
Others threw the server into a tizzy winding up with the dreaded error 500.
A few actually worked as advertised. I'll include a tweaked version here for the benefit of all:

<IfModule rewrite_module>
RewriteEngine On
RewriteBase /
RewriteCond %{HTTP_HOST} !^www\.example\.com [NC]
RewriteRule ^(.*) http://www.example.com/$1 [R=302,L]
</IfModule>

This version goes in the server or virtual host context.
It will temporarily redirect any domain request that is not www.example.com to www.example.com.
If you want this redirection to be permanent, change the 302 to a 301.

If you want to use this in the .htaccess context just remove the <IfModule> and </IfModule> directives.

Also be sure FollowSymLinks is in effect in your context. I have tested and currently use this version on my server so I have undeniable proof it works!

Hope this makes it easier for someone else to find than it was for me.

If you want the details on how this works, please use the Working with Apache Redirection link topside to get to the article.


Any questions, complaints or whatever?, Please feel free to leave a comment or two.

Enjoy!

New Apache Servers section added to our www site
We have just added a new section on Apache Servers to our www.aitechsolutions.net site. "Using Redirection on Apache servers" is the first installment in this section.  Redirection on Apache servers discusses why you may need to use redirection and describes each type of redirection giving example situations and actual directive syntax.

mod_rewrite, ServerAlias, Meta Refresh and DNS configurations are also discussed.
 
There are links to RFC's, Apache's documentation, and an excellent, easy to understand IMO, intro tutorial on Using Apache's rewrite engine, mod_rewrite, at http://forum.modrewrite.com

We have also posted a new Site Map page, available on the home page, that shows at a glance the main topic pages and provides a way to quickly jump to your favorites.

Another new page is the How to link to Us! page that gives you the markup so you can easily copy and paste a link to us directly on your web page. Besides just the home page, there is also markup to link to the Networking, PC support, and web site and Servers sections so you can use a link that relates better to the particular needs of your target audience and site theme. 

As usual, we have more pages in the works.  Almost completed is the the 2nd installment to our Building a quality and SE friendly website series, which will cover topics such as: using link validators, page viewers, how to use nofollow for pages and links and more. Look for it soon!

Also, We are thinking about adding a wiki and have been doing some testing with pmwiki. If anyone has any suggestions on a free, open source, flexible wiki that will run on Apache using flat files or mysql, feel free to post your comments and recomendations.

Thanks!

'Till next time,

Enjoy!

Matt Cutts - Top Engineer at Google Gets his Blog Hacked..or did he?

It was just after midnight, in the wee hours of april fools day. I was perusing the google webmaster forum to see who I could help and pick up some tips when I (Abracadabra)  saw a post with a link I found interesting. It was
http://www.mattcutts.com/blog/google-supports-meta-noodp-tag/  

But to my surprise, instead of the words of wisdom I expected, I found a big black page reading "This
site has been hacked" "The Black SEO Team" 
I the posted to the thread my findings. See this link:

http://groups.google.com/group/Google_Webmaster_Help-Indexing/browse_thread/thread/de2ec19cb52a1d4c/e4936ee377dad548#e4936ee377dad548

Then everthing went aflurry. Posts started appearing in forums, Blogs and even on DIGG.

What a headline.

No I can't take all the credit. I imagine many others noticed it too. When their rss feed died it was probably a good clue.

To my knoledge, I was the first in the Google webmasters forum to post it. That much I do know.
It was pure luck though.

It was fun to be there in the beginning of it all and following the wave.

BTW, on another note I added a couple of new pages on our main site:

http://www.aitechsolutions.net

Topics concern using HTML validators and the first page of a tutorialette for HTML on using the target= attribute of the anchor element. IMHO it makes the _parent option value more understandable than some explanations I've seen out there. Enjoy!    FYI, I have 4 more pages in the works to be posted this week.
 
Oh, I almost forgot,

To find out what really happened to Matt Cutts Blog try this link:
http://www.mattcutts.com/blog/april-fools-day-2007/ 


Thanks for visiting and have a great day!

We welcome comments!
