It isn't, that is what is puzzling me. They are all SNAT clients. The
communication that I am referring to being blocked is BEHIND the ISA 2004
Server.
Lan --> ISA 2k4 --> DMZ --> ISA 2k --> Internet

Why is your ISA between the clients and the DC?
Are your clients using the FW client?

I have been testing ISA2004 for a few weeks now to replace my existing ISA 2000
servers. Everything has been going very well but I
was testing while no users were on the network.
Yesterday I put the ISA 2004 server in place of my Internal ISA 2000 Server
(back to back setup) and the network came to a
screeching halt. I had tested and configured all the basics (http, mail, ftp,
etc.) while it was just myself and everything was
fine. When all users were on the network they were working spotty.
I checked the logs and noticed that a lot of internal network talking (DNS,
NetBios, LDAP, etc) was being blocked between internal
clients and the domain controllers. Even the domain controllers were being
blocked from communicating with each other. I have
checked isaserver.org and MS knowledge base but can't find anything like this
happening. For a quick fix I tired creating a rule
that allows all traffic from internal to internal but that didn't seem to work.
Any idea what I might have configured wrong?
