We have a customer who has a main office with 20 servers (3 Domain Controllers) and 150 clients. They have a 10MB LES10 (Lan Extension) running to a remote DR location where they have 7 servers (1 Domain Controller) running DoubleTake (replication software).
The LES10 is a Telecom supplied "point to point" connection over fibre - it doesn't have routers or anything.
We have been looking at AD Sites and services. The servers in the Office are on the same subnet as the servers in the DR site. How can I stop the clients/servers in the main office from going over the 10MB link to the DC at the DR site and instead use one of the 3 on their GB internal LAN.
I have created an AD site called "Office" and the 3 DC's are in that. I have put the subnet address in and allocated it to this site. I have created a second AD site called "DRSite" which has the single DC in.
I need to stop the Office servers from using the DR DC's and the DR servers from using the Office DC's.
Can anyone offer any guidance on if it is possible to setup two sites in AD Sites and Services over a single subnet or should we try and stick a router in between and go with seperate subnets?
