You have to allow dhcp to your trusted network via the system policy.

Subject: [isalist] OT DHCP problems.

Server is 2003 std edition, isa 2004.
I have DHCP, DNS , and ISA all on the same server (, seems
logical for a home office. I had 2003 and isa 2000 running for several
years this way with out issue until Sunday when I went down to the
office to find that wonderful smell of fried electronics. Needless to
say that motherboard is done.
So on went 2003 and ISA 2004, all was finally well (not sure about
2004's interface yet. suppose it has to grow on you) until I moved my
switch.. now my dhcp server refuses to assign IP's.
I have replaced the NIC, bypassed all the wires to and from the new
switch location. Tried a hub instead, anything I could think of. No
If I assign an IP to the clients all works fine, doesn't seem to be any
issue with throughput on the network.
Anyone have any reasonable explanations or ideas. I can live with
specifying IP's to the clients, but I should not have to... it should
