Question

Answer 1

In SSMS, set the database to read-only then back. The connections will be closed, which frees up the locks.

In my case there was a website that had open connections to the database. This method was easy enough:

1. Right-click the database -> Properties -> Options
2. Set Database Read-Only to True
3. Click 'Yes' at the dialog warning SQL Server will close all connections to the database.
4. Re-open Options and turn read-only back off
5. Now try renaming the database or taking it offline.
