  I ran into to this this AM as well. I had to change my password this morning and when I changed it back to the old one all worked fine. We still have a NT domain not AD. Anyway hope this helps.

  After encountering this error, I deleted all unused datasources, some of which didn't work. This seemed to of done the trick.
  
  Therefore, delete any DataSources that do not work.

  I have the same issue. Very frustrating!!

  I have tonnes of code to rewrite if I cannot fix this bug!! Please help! Please do not suggest re-installing VS2005.

  I have the same thing, Not modified the data sources for ages, now a user wants an item adding to the database so I was about to modify to use the new item and voila.

  Nothing works I have removed all the data sources (shows no data sources at all) and I have tried to add a data source and got the same message every time.

  I cannot see any other method around this, does MS expect you to completely rewrite the application to get around this .

  Even after three installs of visual studio and Sql server, no help. I erased the hard drive and re-installed windows, then vs then sql and all works. A very sad way to have to do something, but. On the server I had yet more fun from the domain change. All is now working.

  I found a relevant bug report (FDBK18994) in
  http://lab.msdn.microsoft.com/productfeedback/default.aspx
  the MSDN Product Feedback Center.

  I solved the problem by renaming the VisualStudio folders in
  ..\Application Data\Microsoft
  ..\Local Settings\Application Data\Microsoft
  to VisualStudioXXX

  I had installed Visual Studio Team System (after I got the CD-ROMs in the mail) on top the express editions of Visual C# and Visual Web Developer. I did not experience any problems for several weeks. After renaming the two directories, I have a cleaner looking GUI that has Team Explorer and Class View tabs. I even have File-New-Project. Now I understand why the labs and webcasts have looked different from my version.

  Have you checked the VS 2005 Beta site to see if this bug has been reported, or has a workaround

  Sunday, we changed our domain name, (parent company deemed we fit under thier domain) So I promo'd our server and removed our domain and then promo'd it back to their domain. when I changed my computer to the new domain, I found all of the programs which ran perfect on the old domain, now would not even start. I figured maybe just go in and change the datasource to reflect the new domain. When I tried to access any data function, I get a pop up "Unable to add data connection. Key not valid for use in specified state." Nothing mentioned prior in this string have worked. HELP!!!

  This fix is temporary for me.  Every time I log off and back on, the problem reoccurs.  My work-around is to delete the data connections and rebuild them.

  This solution worked for me.

  1. Open the registry

  2. Rename [HKEY_CURRENT_USER\Software\Microsoft\VisualStudio\8.0]

  To [HKEY_CURRENT_USER\Software\Microsoft\VisualStudio\8.0back]

  3. Restart Visual Studio
