Firewall Client overrides DNS server IP - 24.May2008 11:48:03 AM

Hi,

I installed Firewall Client (ISA Server 2004) and can very well access FTP now, my client machines are configured to obtain IP from a DHCP server in the domain and it delivers DNS IP also.

I noticed at the command prompt by executing ipconfig /all that firewall client has changed the IP of the DNS on this machine therefore group policy could not be processed and an application is also not running.

How do I prevent firewall client from overriding DNS?

Please Help

changed it to 192.168.0.1, the IP of my modem (my ISP Airtel calls it router).

We have a DSL connection the modem / router's IP is 192.168.0.1, The ISA server machine has two NICs the IPs are 192.168.1.253 (Internal) and 192.168.0.254 (External). The later one's default gateway is set to 192.168.0.1 and DNS 202.56.215.54 and 55 (ISP's DNS server addresses).

I configured this server as edge firewall. Everything works fine the problem occurs when I install firewall client, the client machines receive IP settings from a DHCP server, since it is a windows domain a local DNS Server (192.168.1.2) is also set on the client machines for the AD group policies. This DNS IP (192.168.1.2) is overriden by 192.168.0.1.
