DFS Namespace stops working after Transferring PDC Emulator role

Hi Techies!

I am having Windows Server 2008 R2 Enterprise edition x64 bit based File Servers. I have domain based Namespace with namespace servers as Domain Controllers itself as well as File servers respectively for different Namespaces. I am getting the issue after transferring the PDC Emulator Role to new Domain controller running on Windows server 2008 R2 std edition. The Namespace enumeration fails and I cannot query the domain for namespace although the accessibility is fine if I traverse the namespace through UNC Path. Can you please help me?

Regards,
