Q: During Team Foundation Server Setup I get one of the following errors: 26201, 26204 or 26205. What's wrong?
A: 26201, 26204, 26205 are all SQL-related failures. Verify the following:
- Connectivity - Verify the Database Tier computer can be accessed from the Application Tier computer.
- Common Domain - Both Database Tier and Application Tier computers need to be in the same Windows domain (not workgroup).
- Application Pool Identity - The Application Pool Identity must be a Windows domain account.
- Setup Account - The Windows domain account that is used to run Team Foundation Server setup on the Application Tier computer is an Administrator on the Database Tier computer.
- Clean Database Tier - If you previously ran the Team Foundation Server setup, you must remove the databases added by setup and delete the Work Item Attachments share (WorkItemAttachments) and folder (C:\VSTS\WorkItemTracking\Attachments) on the Database Tier computer. Even if setup does a rollback, it does not clean-up the Database Tier computer.
- SQL Server Running - Verify SQL Server restarted after completing SQL Server installation.
