Absolutely!
More information needed:
Are the DNS servers in a DMZ or LAN?
How are they set up on ISA to allow traffic to/from them?
Do you have forwarders setup on them?
Are they part of your internal Domain?
What DNS servers are listed in the TCP/IP Properties pages of the DNS
servers?
Are they running MS-DNS?
NT 4.0 or Windows 2000?

Subject: [isalist] DNS problems, DNS servers behind firewall
http://www.ISAserver.org
Since implementing an ISA solution a few months back I have been plagued
with transient timeout problems for external users accessing our sites.
Both DNS servers are behind the firewall. Sometimes, restarting ISA
services would alleviate the problem, but only on a temporary basis.
I have now removed one of the DNS servers from behind the firewall and
put
it directly on the ADSL feed. Presto, timeout problems have disappeared.
Does anyone have some insight into this? Shouldn't I be able to have
both
DNS servers protected?
