There is a webchat tonight by Microsoft on the upcoming Windows Server 2003 R2.

It'll hopefully cover the new quota and file filtering thats included.
Can't wait for these features, the users won't know whats hit them :twisted:

File Server Resource Manager
Please join a session with members of the File Server Resource Manager team who will answer your questions on the new FSRM component in Windows Server 2003 R2 and how it can be used by IT administrators to understand and control the type and quantity of data stored on their servers.
