Exchange 2k3 over site-to-site VPN (RAS)

[HKNinja]

Hi guys,

I run into a problem with my Exchange server over Site-to-Site VPN. I have 2 sites (site A and B) that are connected via DSL over L2TP RAS. Exchange 2k3 Enterprise is on site A. Everything is working fine over the VPN. Replication, DNS lookup, etc are all good. Clients on both sites can communicate w/ each other no problem. All clients are on Windows 2000 Pro (that's why I can't use RPC over HTTPS.)
Problem occured on site B. Site B's clients' Outlook cannot resolve or connect to Exchange although pinging Exchange w/ perfect replies. When "Check Name", all site B clients got "The connection to the Microsoft Exchange Server is unavailable. Outlook must be online or connected to complete this action." message. Anyone know what I'm missing here? Thanks a bunch.

Oh, one more issue is that for some reasons, the user's roaming profiles are not copied from site A when users login on site B. I don't know if this has anything to do with the problem.

Do you have the Global Catalog enabled on Site B's DC?

No, I didn't. Do I have to? The GC is on site A. How do I enable GC on site B? Thanks, Neill.
