Answer 1

If you open SQL Server Manager on your TFS Server application tier using "runas" to open it under the same credentials that you expect TFS to use you should be able to diagnose more:

1) install SQL Server Manager on TFS AppTier 2) right-click on the SQL Server Manager icon and select 'run-as' ( you may need to hold alt) 3) enter the TFS Service (refer to TFS Installation Guide) credentials to open 4) try to connect to your SQL Server If you cant connect verify that SQL is installed where you think it is and that there are no firewall issues for the standard SQL ports.
