Hi All,

I have a simple install of ISA 2006 and all has been well for sometime. My setup is

3 Eithernet cards

10.0.0.1 - WAN to router
192.168.100.1 - To pupil Network
192.168.200.1 - To Admin Network

I have a few users including myself that access via VPN. I got a complaint about shares and other resources including exchange will not function correctly.

After looking at the system events I see a warning event: 20169 Unable to contact the DHCP Server, The automatic address: 169.254.x.x will be given to dial clients.

Nothing has changed in the setup. After reading Toms artical on DHCP relay, I added the rules in and the agent to RRAS and a restart, the event still remained. I also clear down leases incase DHCP could not allocate the 10 it wanted.

The DHCP Server is located on the AD Server on the 192.168.100.x network.

I have also noticed that in RRAS, right click properties of the sever and clicking the IP tab. I can see that "use the following adaptor to obtain DNS & DHCP" is set to the 192.168.200.x network where there is not such server.

I dont want to just click and change it there as I know it can mess up ISA. Where in ISA can i tell it to obatain DHCP from the the 192.168.100.x network?

Any help or tips on troubleshooting would be great

Many thanks for your time

Paul
