After an upgrade to Exchange 2007, you may get some errors related to your account and User Principal Name (UPN). This particularly occurs when you have users where no domain name is filled in at User Logon Name at the Account tab in Active Directory.

In my test environment, the following error occurred during the Readiness Check of my Exchange 2007 installation:

Setup encountered a problem while validating the state of Active Directory: An Active Directory error 0×8007203A occurred while searching for domain controllers in domain [domain name] : The server is not operational.

After the installation of Windows XP Service Pack 3 (SP3), you might face some trouble with the Automatic Updates feature in Windows XP. In my case, I wasn’t able to install new updates.

An example of the error I got was:

Security Update for Windows XP with Windows Media Format Runtime 9.5 and 11 (KB941569) failed

When you’re running Vista with UAC enabled, you might get the following error when trying to print a website to PDF:

Save PDF File AS
You don’t have permission to save in this location.
Contact the administrator to obtain permission.
Would you like to save in the [username] folder instead?
