6. Your problem:

I installed SIP Server 2.2.4.5 Academic and configured it to use a third party database, SQL Server 2005 Express. The SIP server starts and I see records in the t_registered table from my SIP UAs. However, if I click the User Authentication tab or Registered Clients tabs in the Admin tool and try to add a new user or view users, I always get the response "Database error :null". I can't add and Users. Anyone have any ideas on the cause and solution of this error.

I restarted the machine that SIP Server was running on and this problem disappeared.
