Hello All,


We have two building that are a couple blocks apart they are connected via cisco 2600 routers going through a VLAN provided by Cox.  There are two domain controllers per segment one of them on each side is running DHCP.   Currently the Global catalog is located on segment B.
Break Down

Segment A        Segment B
(Main)               (Corp)
2 DC's                2 Dc's
1 DHCP              1 DHCP
192.168.0.0        172.16.10.0

 
The problem we are having is that people on Segment A are pulling IPs from the Segment B and vice versus.  Any ideas/suggestions will be helpful.   thx.

Turn off BOOTP on the routers if it is on.  I'm not familiar enough with the Cisco 2600 to give you step by step instructions.

On the Cisco 2600's is there have an ip helper-address configured?  If so, that would be why DHCP requests are getting between segments. Normally a router won't forward them because they are broadcast for that network (segment/subnet) only.

You can turn that off with the "no ip helper-address w.x.y.z" command.

Cheers
