        Speaking of which, I have two of those, "Domain Controllers" and
"Domain Controllers(1)" on my system...  Hmmmmm

        Here's what I'm experiencing. We have somewheres around 15 DCs
in the domain. Two of them are on the local subnet. I recently retired
one of the two local DCs. Then I noticed that our Internet connection
got real slow--mainly a delay of, say, 20 seconds before a page would
load. I started poking around with DNS. If I changed the WAN card on the
firewall to point at an external DNS server, the web sped up a bunch.
But you probably know that this isn't a good arrangement and pretty soon
thereafter we got other problems happening. So I pointed DNS on the WAN
card back to the LAN address on the firewall. The other problems went
away but slow access came back. So I poked around on the firewall a bit
and found that Domain Controllers computer set. I noticed that the list
in there was out of date, and both of the DCs on the local domain that
were in that list are now retired. So I'm guessing (maybe incorrectly)
that that somehow bears on this problem--like maybe the ISA server is
now trying to talk to DCs on remote subnets since it can't find the two
DCs on the local subnet. So I was hoping if I could edit that computer
set I could make the problem go away.

         

        Anyway, that's what's happening. Maybe I'm way off base? Any
suggestions?

        The domain controllers computer set is one of the great
mysteries of the
        ISA firewall. You won't find any documentation about it and many
will
        deny its existance. Never bring it up in polite company.
