Now managed to find a blog from Microsoft on the subject. http://blogs.msdn.com/b/psssql/archive/2009/09/11/fun-with-locked-pages-awe-task-manager-and-the-working-set.aspx

Gail,

Thanks for the information. That explains why everything is working as it should be and i am just worrying over nothing.

Thanks everyone.

Not a silly question as it was one of things I double checked as well. Max Server memory is 6144 MB.

It is the memory usage in Task Manager that I am viewing.

We are running SQL Server 2005 Standard Edition 64 bit.

The AWE flag is not set.

We are using the lock...
