[isalist] Re: "Domain Controllers" in ISA 2004

Good idea! Thanks!

 

Any way to find all the places in System Policy that “Domain Controllers” 
is used, besides just eye balling it?

 

Thanks,

Rob

Rob-

 

The "domain controllers" list is a built-in, non-user-changeable object that is 
populated during installation time by the ISA server polling AD for existing 
domain controllers.  The default system DNS system policy is set to use the 
domain controllers object.

 

Just create your own Domain Controllers object (like "DC's" or something) and 
populate that with the actual DC's.  Then remove the "Domain Controllers" 
object from the System Policy and replace it with your "DC's" object (and 
anywhere else you use that object) and life will return to normal.

        The ISA server is, indeed, a DNS server. I’m looking at The Book and 
it does, indeed, say that the external interface should have NO DNS entry. 
I’m not sure how the internal IP address of the ISA server got in there. I 
suppose I must have put it in there, but I don’t remember doing it. Anyway, 
it’s out now.

        Is the ISA server a DNS server, too?

         

        If not, I would think you’d want to specify the DNS server IP 
addresses on the NIC that resides on the same network as your DCs. It would 
probably be a good idea to remove them from the other NIC.

        Yes to both of your AD questions. The ISA server points only to itself 
(the internal address) on both NICs.

        Rob,

         

        Are sites configured in Active Directory and do you have subnets 
defined for the sites in Active Directory?  You’ll also want to check your 
NIC configuration for DNS servers on the ISA box(es).  Are those settings up to 
date?

        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?

         

        Rob

        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.
