accessing DFS shares problem from Windows 2003 R2 SP2

Hello all!
We have a trange and annoying issue in a customer domain: The domain itself
is based on Windows 2003 SP1 (non R2). Within that domain we have recently
installed several Windows 2003 R2 SP2 servers that host the DFS resources.
Now the problem shows up that - when we want to access these resources from
our Windows 2003 R2 SP2 based citrix servers - the connection cannot be
established.
Network traffic scans show us that the initial SYN/ACK traffic is the only
thing that happens, no SMB session is started to actually find/open the
resource.
Whenever we access the same DFS resource from an older release (W2K3 SP1
(non R2)) then the session is setup successfull.
Who has seen something like this before or has any suggestion for us?

Thanks in advance.

Did you do a schema update on your DC's? This has to be done because
R2 has some DFS enhancements that require it. If your getting events
6012 and 1202 in the DFS Replication event viewer log on your R2 DFS
servers then this is your problem.

We solved the problem by installing KB925066 on our Terminal Serververs. This
fix solves bugs in the VSS-client component of Windows 2003 R2 SP2.
We also entered a reg-key that removes the Previous Versions TAB from the
explorer, and disabled previous versions on the actual DFS shares too.

Browsing DFS is as it should be now.

You are right in a way too. The Schema is not updated (yet), but I don't
think it would have solved the issue in our case.

Thanks.
