Terminal Server clients cant browse DFS Shares

When navigating DFS shares from a terminal server session, windows explorer runs slow and hangs up w/o any error messages. this issue appears when using "back" or "up folder" in windows explorer (after 2 or 3 folder changes) and also when navigating 5 or more subdirectories.

Navigating via \\servername\sharename or \\Namespace\Sharename creates the same problem.
To stop the hour glass I open task Manager and when I open up Applications tab I see the path I am trying to browse to duplicated and Not Responding. Navigating to a non DFS share and browsing through subfolders works ok without any problems.

I have (4) Win2k3 r2  DC's / (2)File servers running DFS
and (2) Win2k3 r2 x86 Terminal servers

Another interesting point is that this issue does not seem to appear on XP-Pro PC's whether browsing via \\servername\share name or Namespace\sharename.

Is NetBIOS over TCP/IP Enabled for the Terminal Server?

jbuzekAuthor Commented:
Yes, NetBIOS is enabled with the Default setting within TCP/IP on the terminal server. I disabled it and unfortunately this had no improvement on browsing subfolders within the DFS share. Thanks for posting.

Silly question, but is the DFS root's alias propagated properly through DNS and WINS?

Yes, the DFS root alias is propagated and available from any server. Thanks

We wound up opening a ticket with Microsoft. After trying four different patches this one was the key http://support.microsoft.com/kb/925066. On a client computer that is running Windows XP or Windows Server 2003, you try to access shared files on a Distributed File System (DFS) server in a domain environment. However, Windows Explorer may stop responding in this situation. This issue may occur because of an error in the Twext.dll file. When this error occurs, the client computer sends many referral requests to the DFS server after you try to access shared files.
