I am facing this problem after our VM is moved from one server to another server. Earlier in old server, I used to connect to TFS using DefaultCollection. I have all my files check in this DB. Now when I am trying to connect to this collection, I get the following error. Attached the image. Please help..where should I change the connection so that I can connect to this and restore my old TFS ..Team project..

I click on DefaultCollection in Team project collections in TFS Explore..I get the error. Please help.

While this error message can have multiple causes (invalid credentials, SQL Server not available/not started, etc.)

You could try to narrow down this issue by below possibilities:

  • Incorrect SQL Installation order especially if you are using Express edition
  • Database In Recovery
  • Database Out-of-Sync – during migration to newer version of TFS
  • Permission of Service Account is not right
  • SQL Database not running or not reachable
  • TFS Proxy not reachable
