I've had a strange problem on multiple W2K DC's. The server is multihomed having a interface card on the LAN and a interface card pointing to the backbone for internet access. Internet access works fine through ISA server. The problem comes with DHCP and WINS. I can install both services, but the services can not find the server. Error message "Cannot find the server". I've been looking on microsoft technet and support, but have not found a solution. DNS works fine, No firewall or filters are activated on ISA. Someone must have experienced this before.

Both Wins is designed to function on multihomed servers. The links do not relate to the problem.

First of all ISA doesn't allow access w/o explicit permission to get through the firewall, so something must be allowing traffic through.

Next, it is agreed that ISA does funny things to any machine running it. I would not put any other service on a machine with ISA and certainly wouldn't put DHCP and you proably don't even need WINS unless there is some application requiring it.

The ISA server is chained to the main ISA server on the backbone. Therefor no firewall is needed or configured on this internal proxy. And I worked a lot with deployment and configuration of the ISA server, and have never experienced any unexpected behaviour. I don't see any problem at all combining ISA and DHCP. You can define that DHCP supports only the internal network card. WINS is needed to support old NT 4 computers, I don't need all that NETBIOS name resolution broadcasting.
