AD replication over VPN problem

Hello there,

I'm attempting to replicate my local AD over VPN to a remote machine as an RODC

My local AD is on a windows server 2008 R1 sp2

Remote machine is a windows server 2008 R2 sp1 and has a public IP

I'm using a windows PPTP vpn connection.



The two machines seem to be communicating well, I start the dcpromo and fill every bit of information, replication starts, and always fails at the same step "The Operation failed because : While promoting Read-Only Domain Controller, failed to replicate the secrets from the helper AD DC. The RPC server is unavailable".



I used to have the rpc error thing from the very start because i did not tell the remote machine to use the local AD as prefered DNS.

I have tested the replication with a local machine and everything went ok,

edit : at first this looks very much like a dns error, but, then i edited the hosts file on remote and local machines and added the vpn addresses (10.0.0.0) so that there would be no mistakes, and i still get that error at the same step.

Thanks for your help.

Your better off replicating on a local network and then change the ip and routing etc for vpn rodc.
