MORE INFORMATION
After you apply this hotfix, you must enable trace flag 9052 for the fix to take effect. To do this, follow these steps:
- Start SQL Server Enterprise Manager.
- Right-click the instance of SQL Server, and then click Properties.
- Click the General tab, and then click Startup Parameters.
- In the Startup Parameters dialog box, type -T9052 in the Parameter box.
- Click Add, and then click OK.
- In the SQL Server Properties dialog box, click OK.
- Restart SQL Server.
Note You can also dynamically enable the trace flag by running the dbcc traceon(9052,-1) command. If you run this command, you do not have to restart SQL Server. However, you must run this command every time that you restart SQL Server.
