I've recently configured 2 servers in AD on the same domain level. They are physically separated and permanently connected through a site-to-site vpn for dfs replication.

All well, but when users connect to either site through vpn (from home e.g.) they can't use the domain level method: \\domain.com\data Internally this works perfectly, resolving domain.com when connected through vpn gets the correct IP.

I've tried Google to figure things out. What I was able to find was that more people have this issue, no real solution found though.

Can anyone explain why this is happening? Especially a solution would be really helpful!

Thanks in advance.
