We have a BDC that will not sync. We can ping the IP of the BDC, but we can not see the BDC in the svrmgr. The users log on through this BDC. They can see all of our shared drives and their Outlook is working. If a user password expires we can notchange their password. This is a remote BDC, but still connected to our network.
When we bring it to our comm-room it works, but as soon as we take it back to its location it want snyc and we can not see svrmgr.

A BDC in a remote location that is on a different subnet than your office PDC always has problems. Name resolution (using WINS) does not work too well crossing subnets, going over routers. It just doesn't.
The best solution I have found (for I had this same problem a year ago) is to add an entry in the LMHOSTS file on both the remote BDC and on the office PDC, pointing to each other.
So, if your PDC is called MYPDC and has an IP of 10.1.1.5, and your BDC is called MYBDC and has an IP of 10.2.1.5, AND your NT domain is called MYDOMAIN, put the following in the LMHOSTS file on the PDC:

10.2.1.5 MYBDC #PRE #DOM:MYDOMAIN

And in the LMHOSTS file on the BDC, put in:

10.1.1.5 MYPDC #PRE #DOM:MYDOMAIN

That should take care ofthings for you.
And here is a TechNet article (Q180094) on LMHOSTS files and using them for domain validation:

hope this helps
