START -> All Programs -> Microsoft SQL Server 2008 R2 -> SQL Server Management Studio<\/p>\n\n\n\n

Connect as normal and right-click on the SQL Server (top left) and go “Activity Monitor”.<\/p>\n\n\n\n

The Activity Monitor will show the queries been run, the user, the computer been run from etc. This can help narrow down clients chewing up the SQL Database and\/or show the databases and queries causing the most issues.<\/p>\n\n\n\n

You can also right-click on a Process listed (by a user\/computer) and go “Kill Process” to end the SQL client connection (useful if you want to force a user to logout of sql to free up a client license etc.).<\/p>\n\n\n

Problem:
When I tried to launch the Activity Monitor on a Windows 7 x64 client, I got the error below:<\/p>\n\n\n\n
