This is a DNS issue with ISA Server (obviously)

How is DNS configured in your environment?

Cheers

Hi,

Check Jason blog post regarding the recommended settings for ISA Server Network cards : http://blog.msfirewall.org.uk/2008/06/isa-servers-recommeded-network-card.html

You should not put any DNS Entry on the External NIC, only the Internal NIC should have a DNS Entry and it should point to your Internal DNS Server where it should be able to forward external requests to your ISP DNS Servers. Check this article to know how : Internal DNS Forwarding Through ISA Server 2004/2006
