Rick, thanks for the suggestions.

First, the general setup is this: sites A, B, and C. Let's call A the hub
and C the "problem" site. Each has one DC that runs its own DNS. Each has
been designated a GC. They use PPTP tunnels to reach the hub -- this
communication appears to be working fine.

To answer some of your questions:
- There has always been one server per site. The "move" was only within
dssite since when you first run DCPROMO over a WAN, it does not put it in
the proper site automatically.
- There are two IP site links: A-B and A-C, each containing only their
respective members. Subnets and static routes in rrasmgmt.msc are correct.

I suspect this is a DNS problem but do not know how to resolve it. From any
site, nslookup (pointing to the local DNS server) finds all the other DCs by
full name. However, if I look in dnsmgmt, I get different results depending
on the server. For example, from the hub (A), there is no entry for site C
when I look in: ..._msdcs>dc>_sites> Also, under ..._tcp, there are listings
servers A and B but not C for the _gc, _kerberos, _ldap, etc.

I will spare you more minutae. Any ideas how I can get A to recognize C in
DNS? I have tried ipconfig /registerdns and netdiag /fix both to no avail.

Thanks again.
