Compatibility between Symantec File Share Encryption and Microsoft DFS-R & VSS

Hi,

We are planning to use Symantec Encryption Management Server (EMS) for managing File Share and Drive Encryption in our environment.  Some of our FIle Servers use Microsoft DFS-R & VSS. I want to know if there are any potential issues or compatiability issues that can arise when used with Symantec File Share Encryption? Any help in this regard will be much appreciated. Thanks.
