DFS not working over VPN

Dear all,

I am migrating a DFS from a Windows Storage Server 2003 to a Windows Server 2008 R2. Everything went fine except one thing.

I cannot access the DFS over the VPN.

Internally everything works.

Over VPN I get access the netlogon and sysvol folder but I get the message \\FQDN\DFSname not found after some time

When the DFS was located on the Windows 2003 Server I could access it over VPN.

So Browsing \\FQDN\DFSname does not work, ping to FQDN works,\\FQDN\ gives me sysvol and netlogon shares.

Any ideas ?

Kind regards,

Kenny
