Windows 2003 Site to Site VPN & DFS Replication

Djrobluv asked
Last Modified: 2010-05-18
My question has a two pronged attack. I have a client that will be getting a Windows Server 2003 R2 system. An he has asked that I bring his server that is being replaced (Windows 2003 Server R2) to my office and setup as a backup system. Both systems are Domain Controllers/ File Servers. I want to use DFS Replication to replicate his data between both systems. AD changes will be replicated also. I have setup a similiar lab test with my home server (2003 R2, 1 NIC) and a spare system (2003 R2, 1 NIC). I have made the spare system a secondary DC on my Domain. I took the spare system into work and connected it to my lab network. I created a Demand Dial connection using RRAS to connect to my server at home. Here are the problems I'm having.

1) Spare DC in the office can ping FQDN of the DC I have at home, but the DC at Home SOMETIMES can't ping the DC in the office. I think this problem due to changing IP address when spare DC connects to home RRAS. DNS reflects a different IP. Need to somehow setup a Static IP for incoming demand dial connection. Need help figuring this out...

2) DFS - My home server is the source for DFS and the spare in the office is the target for DFS. When I go to setup DFS namespace server for the Office DC, DFS says it cannot contact the specified server. Even though I can ping its FQDN. Need help figuring this out.

I think once the RRAS connection with the static IP address is resolved it may resolve my issue with DFS. So more emphasis on RRAS would be needed. I'm familiar enough to make connections in RRAS but not advanced enough yet for more advanced functions of RRAS.
