i have a public domain and two private network each other in office geografically distanced (and different domain controllers) connected by a router. I need to use the same mail server on both private network in order to have two post office but one public mail server. Both network have access to internet with the same provider. How can i do that?

I would like to address this in 2 parts.

First part is to estabilish the connectivity between the two distant sites.Try connecting the two servers(private domain is not a relavance in this case, except creating the OU name in the exchange server and connector authentications) using PPTP (i.e.VPN connectivity).Before connecting make sure your firewall allows PPTP on both sides.

Second part is to choose the email gateway to connect to the internet world which would be connecting to your public mail server.After choosing anyone of them(try tracert to check out the number of hops to your public server)configure IMS.

Then using the VPN network try connecting the two private domains using site connector or X.400 depending on the bandwidth size.Replicate your directory using DRC in exchange

All the best.

1.Suppose now, that both office are connected but with different service provider, with PPTP, is it applicable?
2.What about performance when using DRC for directory replication?
