SYMPTOMS
You are running a Windows Server 2003-based domain controller that hosts the primary domain controller (PDC) emulator role. On this PDC, the private bytes that the Distributed File System service (Dfssvc.exe) process consumes continue to increase. The Distributed File System (DFS) service may eventually stop working. In this situation, you have to restart the DFS service to recover from this problem.

This problem occurs only on a domain controller that hosts the PDC emulator role.



CAUSE
This problem occurs because the DFS service leaks private bytes when the DFS service enumerates DFS roots.
