I never worked with ISA but why would you want to use DHCP if all is well with static IPs? I never understood why the world loves DHCP so much.

It sounds like that there is still a policy blocking it. I hope you don't have Norton running or something similar.

Run services.msc
Is DHCP enabled & started?

Are the clients set to get a dhcp address?
When you say outbound are you trying to assign ips to people on the internet?
what is the "client side"? Wan or Lan?


"I never understood why the world loves DHCP so much."

#1. it scales to large networks
#2 centralizes ip administration
#3 allows you to update/change the ip plan dynamically
#4 allows you to do static ip assignments with ip reservations
#5 dynamically updates MS DNS

Why workstation static ips don't scale.

#1 static ip assignments require you to document and update that document any time a change is made. Labor intensive.
#2 does not scale with larger amounts of workstations
#3 labor intensive to then change to dhcp

Hopefully this will help your understanding.

Wanderer, most of the time, in this forum, we are talking about home networks which may consist of a few PCs. I never suggested static IPs for large networks.

Then add to the list

:-)

There are a LOT of large network questions here also dealing with domains, multiple site connections etc.

You didn't mention anything about the machine having 2 NICs, in your first post.
Windows has a hard time with dual NICs.

dhcp should only be associated with the lan nic not the wan nic

Let's try these questions again
Are the clients set to get a dhcp address?
When you say outbound are you trying to assign ips to people on the internet?
what is the "client side"? Wan or Lan?

check the nic bindings under dhcp
the public interface should be disabled [not checked]

Public is the wan interface. The nic facing the internet. Make sure it is unchecked in dhcp console.

first problem is ISA is a edge security software. It is recommended it not be installed on a dns/dhcp/AD server but on a standalone.

is your issue with dhcp or with isa?
