When you have configured Exchange 2007 / Outlook 2007 to use the Autodiscover functionality (autodiscover.xml), you have probably seen this window many times:

“Allow this website to configure user@company.com server settings?
https://server-or-domain/autodiscover/autodiscover.xml
Your account was redirected to this website for settings.
You should only allow settings from sources you know and trust.”

The file thumbs.db is a thumbnail cache. Windows uses thumbs.db to store thumbnail images for Windows Explorer’s thumbnail view. When a folder with images and movies is opened for the first time, Windows creates thumbnails for all these media files. The thumbnails are saved into one file, thumbs.db. This speeds up the display of images as the smaller images do not need to be recalculated every time the user views the folder.

Last week one of my servers had an strange issue. After pressing CTRL-ALT-DELETE to log on, the log on window turned almost completely black (as you can see in the screenshot).
Google gave me the answer, but I still have no idea how this could have happened.

As an system administrator, I know how difficult it can be to solve Windows Update errors. This is particularly the case with Windows Update, because Windows Update always returns generic errors. KB-articles will likely not help you, because these articles are written with theoretical knowledge, and are barely based on real-world scenarios.

After I used CCleaner, I was unable to download attachments with Internet Explorer 8 (IE8).
CCleaner normally only deletes unneccessary files and registry keys. However, in this case it seems that CCleaner has cleaned a little bit too much :)
The following error occured when I tried to download a file with Internet Explorer 8:
Unable to download attachment.zip from www.webaddress.com
Unable to open this Internet site. The requested site is either unavailable or cannot be found. Please try again later.
