We have two locations linked by point to point t1 line. The way we have our network set up is: Location "A" had another t1 linked to internet, root domain server, firewall, and netopia router. Location "B" had netopia router and another domain controller which replicate with root. Location "A" use IP Address range 192.168.20.0 ~ 192.168.20.128 w/ subnet mask 255.255.255.128; location "B" use another half of range. Netopia Router of location "A" has an ip address 192.168.20.2 with the routing table pointing to destination network: 0.0.0.0, subnet mask: 0.0.0.0, and gateway 192.168.20.1 (ip address of firewall). Netopia Router of location "B" has an ip address 192.168.20.129 with the routing table pointing to destination network: 0.0.0.0, subnet mask: 0.0.0.0, and gateway 192.168.20.2 (ip address of Location "A" router).

Here is the problem, if the point to point t1 line get disconnected, no one in the location "B" can access the network or files in the server eventhought there is another domain controller in location "B". Can anyone help.... Thanks.
 
There MUST be a GC in location B. I think this is the problem.

Victor, what is GC?

By the way, all the clients station and server in location "B" has a gateway with ip address of 192.168.20.129 and DNS pointed to DNS Server in location "B".
 
DNS does not really plays matter here... because t1 is down... but anyway, GC - is a Global Catalog Server. Promote your DC in location B to GC server. (link (t1) at this moment MUST be up)

Good luck!

Thanks Victor, hopefully it'll work once I reconfigure my server late tonight. :-(
 
If you use 255.255.255.128 as your mask, and you said you have ip address range from 192.168.20.0~192.168.20.128
