SYMPTOMS

When you try to connect to a SQL Server server with the SQL Server Enterprise Manager, you may encounter the following error message, which is followed by a SQL Server shut down:
sqlservr.exe - Application Error
The exception unknown software exception (0xe06d7363) occurred in the application at location 0x77e89b01.

CAUSE

This assertion can only occur if the recovery model option of the tempdb database was manually set to a value other than SIMPLE, by modifying the sysdatabases.status system table. Please note that modifying system tables in SQL Server is not supported and may lead to unexpected product behavior.

RESOLUTION

To resolve this problem, obtain the latest service pack for SQL Server 2000. For additional information, click the following article number to view the article in the Microsoft Knowledge Base:
290211 INF: How to Obtain the Latest SQL Server 2000 Service Pack

WORKAROUND

Set the tempdb to a SIMPLE recovery model. You can only do this by updating sysdatabases.status to eight (8).

STATUS

Microsoft has confirmed that this is a problem in SQL Server 2000. This problem was first corrected in SQL Server 2000 Service Pack 1.

MORE INFORMATION

The ALTER DATABASE statement and sp_dboption do not allow you to change the recovery model of tempdb. The only way you can change the recovery model of tempdb is to perform a manual modification of the system catalog.
