for a few months now our main office in new york could no longer access our west coast office via the site to site vpn so the west coast server which is a domain controller could not replicate with the new york primary domain controller but just today we got both sites connected via an mpls dedicated connection so i can ping and remote desktop into each site but as expected, when i tried replicating the servers got errors. My question is what would be the easiest way to correct this so west coast site can authenticate domain users properly since now the users are not able to log into their pcs for some reason and are getting errors that no domain controller is available. There is a 2nd member server at the west coast site so could i just promote that to a domain controller and then if it works, demote the original domain controller? Wasnt sure of the steps for dcpromo as well. Thanks in advance.
