When trying to open the administration console for SMSMSE the following message appears:

Unhandled exception has occurred in your application.  If you click continue, the application will ignore this error and attempt to continue.  If you click Quit, the application will close immediately.

Clicking the Continue button leaves the console splash screen showing on the desktop.


  • The Windows Application Event log contains an event with the following message:

Unrecognized configuration section system.serviceModel. (C:\WINDOWS\Microsoft.NET\Framework\v2.0.50727\Config\machine.config line 134)




The .NET configuration file is C:\WINDOWS\Microsoft.NET\Framework\v2.0.50727\Config\machine.config corrupt.




Replace the file C:\WINDOWS\Microsoft.NET\Framework\v2.0.50727\Config\machine.config with a good copy from a different server with the same operating system.

A reinstall of the .NET framework should also fix the issue.
