I have SQL Server Express 2008 installed on a Windows 7 (32-bit) developer workstation. Whenever I run an application that accesses SQL Server the Windows 7 shell hangs when the application closes. Applications like Windows Explorer and Task Manager become completely unresponsive. The task bar will not allow any interaction. The only way to recover the system is to power cycle.
Two of the applications in use when this happens are NUnit and SQL Server Management Studio. NUnit always runs the unit tests that interact with the database fine. SQL Server Management Studio will sometimes cause the problem while trying to explore the database.
The Windows event log does not show any events that are obviously connected to the problem.
I have reverted and reinstalled SQL Server Express 2008 several times.
What can be done to identify what is causing SQL Server Express 2008 to hang the Windows 7 shell?
