For some raeson I am unable to connect to my database via Enterprise Manager anymore, but am still able to execute queries via osql. Here is the message I am getting when trying to connect through EM:

A connection could not be established to SERVER-NAME.

Reason: General network error. Check your network documentation.

Please verify SQL Server is running and check your SQL Server registration properties (by right-clicking on the SERVER-NAME node) and try again).

Any help would be greatly appreciated!
