SBS 2011 Standard server based VPN for inter site AD replication

Hello,

I have a client that currently has 2 sites and is using SBS 2011 on the main site and Windows 2008 std on the second.

I am looking to configure Windows based VPN link(s) between the sites to allow AD replication.

I have currently configured the second site to connect to the Windows SBS 2011 using the VPN wizard on the main office server, and used a VPN client connection on the second site server; but am having communication issues.

I have run repadmin and it shows that the main site is not able to communicate with the second office.

Do I have to create a separate VPN connection from the main site to the second site server to enable 2 way VPN traffic?

Due to project funding restrictions at this time, we are restricted to utilizing a Windows VPN solution; with future plans to migrate the VPN to a hardware based solution.

Many thanks for any assistance and advice

Is the server at the remote location already a DC?

Hello,

Yes it is. It was initially set up using the following procedure.

1. Enable VPN access on the main site SBS 2011 server
2. Connect to the main site from the remote site by establishing a VPN connection.
3. Run DC Promo - took a while to update (overnight)
4. Any updates generally take a fair amount of time.

Runing repadmin shows that there has never been any connection. But there are updates occurring.
what kind of bandwidth do you have between the two sites?
How close are the two facilities?   Close enough that you can take the remote server to the main office and redo the DCPROMO, verify replication, then take back to remote location and run DCDIAG
Apologies about the late follow up.

Both have an ADSL link 5meg down/ 384 up.

After additional research, the AD is definitely replicating. The error report seems to be the RPC service not being found between the sites. I am thinking that rpc is not configured on the server to use the VPN connection. Pretty much everything else is working after using a few other switches when running repadmin.

At this point,  it is not possible to remove the site DC and bring it back to the main office.

Thanks for the follow up.

Thanks, the question has been open for a while, but I have not had any further luck - so at this point - I am closing it as finished.
