Today when I tried to import a new WorkItem type to our TFS-server I get a strange error-message:
===
U:\WorkItems>"e:\Program Files\Microsoft Visual Studio 8\Common7\IDE\witimport.exe" /f newBug.xml /t tfs /p Test
The Team Foundation Server work item database cannot be opened. It may be offline for system administration. Try again later or contact your Team Foundation Server administrator.

The strange thing is that I can export WorkItems definitions and when I try to import to a project that not exists I am informed of that.

I get the same error-message when I use Process Template Editor and I have tried with several different workItem definitions (all validated fine).

Any suggestions?

Please check with your database administrator to find out if work item database is taken offline or set to readonly for any reason.

You can try to edit a work item in the database to see if you can make any edit to verify if it is server side issue.

Thanks
