Hi Hetham,

You Can Do following Steps to resolve the issue/

Check The Primary DNS Setting on Your LAN Card if its IP is other than your domain controller (DNS) then change it also check the perefred setting.

Check also the host file for ISA Server

Check The Rules for Allowances of DNS for client on ISA Server

I Hope it Works

You do not use a host file on the ISA server when it is on a domain - ISA basics.

Dear all ; let me say it in other way: i have 3 ISA server Domain Members where the LAN nic configured with the Internal DNS and the WAN nic configured with Rreal DNS; for 2 of this servers when i request Nslookup it's going to the Internal DNS and on the 3rd one going to the Real DNS.
what it the reason for the either cases ?
I Hope it's clear now
