You could also take a stab in the dark and follow microsoft's advice:
Visual Studio .NET 2003 on Windows Vista Issue List
The information below identifies the known issues you will face when using Visual Studio 2003 on Windows Vista. While Visual Studio 2003 is not supported on Windows Vista if you choose to run it then we advise you to do the following:
* Run Visual Studio with elevated administrator permissions
* Be a member of the "Administrators" group on the local machine
* Right-click the Visual Studio icon and select the "Run as administrator" option from the context menu
Note: You can create a shortcut to Visual Studio and select the option to always run with elevated administrator permissions. Using this shortcut would be the equivalent of the right-click method described above.
Good Luck.

Question is not "Why are you Online"
Question is "Why are you Off line"
