I found in HP documentation that when you RESTORE a SQL-Server project DB or qcsiteadmin DB back to SQL-Server used by QC, you must run 2 stored procedures (actually one-liners) to "fix" SQL-Server’s use of the "td" user.:

Update the td user – Do this for EACH migrated project database (AND the qcsiteadmin_db database if you migrated that too)

*

> 1. Login using ‘sa’ to MS SQL Server’s Query Analyzer, and connect to your
> server.
> 2. Choose the project and run the following commands:
> 3. **EXEC sp_change_users_login ‘Report’**
> 4. You should get the unlinked user (TD).
> 5. **EXEC sp_change_users_login ‘Update_One’, ‘td’, ‘td’**
> 6. This links the "td" user of the QC project database to the same ID of the
> "td" user of the whole SQL server.

Is the "td" user that the two stored proc reference the DB Admin User Name? I want to make sure I have a correct understanding.
This QC instance was setup prior to me joining the company, and the gentlman that did the setup is no longer here.
