I have 2 A/D servers at my main location that replication is working on correctly.
I have 2 remote locations each with one AD DC (Windows 2003 Server).
Replication is not working between the main site and the remote sites.
The sites are connected VPN using Watchguard Fireboxes with wide open access.
Please advise as to what I can provide you with to troubleshoot this issue and get it resolved.
