Should I install our Symantec AntiVirus Corporate Edition on the ISA 2004 server as a client? In the ISA 2004 server Quick Start Guide, it tells me to setup a DNS forwarder on my Internal Active Directory DNS server,to point to the ISA Server. When I go in to do this, everything in the Forwarders section is greyed out. My Internal AD DNS server is a Windows 2003 SP-1 server. And I have a "backup" internal AD DNS server as well. Howdo I address this issue? Cause when I click on the Reverse Lookup Zone name for my local network that I created on the ISA server, it gives me a Zone Transfer error - unable to.
