Since you already have your internal DNS server set up to forward unanswered requests to your ISP's DNS, then no you won't have any problems with setting up your ISA's DNS to point to the internal server. -----Original Message----- From: Greg M. Hess [mailto:gmh@xxxxxxxx] Sent: Wednesday, November 28, 2001 1:48 PM http://www.ISAserver.org Anyone, We are currently using an ISA member server in a Windows 2000 domain. Everything is currently working fine. We have our internal DNS servers configured to forward DNS queries to our ISP DNS servers. We would like to configure our ISA box to use our internal DNS instead of our external DNS so that we may use "custom" DNS names that will only resolve inside the company. Would there be any problems with this? tx. Greg.
