Integrating Win2k3 Server into OD PDC domain (10.4.10)

I have a problem related to what I thought would be a fairly simple procedure.

We have a working OSX Server 10.4.10 Open Directory system, with Windows Services enabled on as a PDC. We have joined approximately 20 WinXP workstations to the Samba domain, and OD users can log into these systems as expected (i.e. authentication works). Virtual Share Points are disabled, we want different home directories for the Mac and Windows workstations.

I have a Win2K3 server that was recently purchased and running the File Server role. We have it joined as a member server to the OD PDC. I want to set up the Windows Home and Profile directories so that they are located on the Win2K3 server. File sharing is set up on the Win2k3 server and share points are valid for local server users (verified via Windows Explorer).

When I log in to the XP workstation (using an account that has its home dir and profile pointed to the Win2k3 shares) I am told that the user’s profile can’t be found. Trying to manually navigate to the share points via the Win Explorer or via DOS prompt fails, with an error message about a failed RPC call and a possible permissions issue. The share points both are exported for “Everyone” with read/write access.

Is this even possible? I realize that most people are joining OSX systems to AD installations, but in this case I just want to set up a CIFS share on the Win2k3 box and access it from the network.

I did test this over the summer and everything appeared to work. Of course now that I want to put this into production it’s failing… 😕
Any help or insight would be much appreciated.

Thanks, jg
