Please HELP !!!!!!! - 19.Apr.2006 8:37:11 AM

I have created a name server (With Windows Server 2003) and published it to the internet. I also created DNS zones and everything was working just fine. I was able to ping that name server from outside our network i.e. from the internet. I was also successful in doing a DNS Lookup. But, as soon as I installed ISA server 2000 SBS, everything stopped working. Now, I am unable to ping or perform a DNS lookup from outside our network i.e. the internet. But, I am able to access the internet from within our network. I have installed ISA 2K SP2 and also its hotfix. But, still its not working. I think there is some problem with the ISA Firewall configuration.

In the Access Policy / IP Packet Filters section, you need to add in the predefined protocols, ICMP Ping Query & ICMP Ping Response (or something along those lines) else ISA Server will just kill the request

Thanks for the help. Now, its pinging successfully. But, the DNS Lookup is still failling. I have allowed DNS lookup and HTTP in IP Packet Filters under Access Policy. But, its not working.
