I have installed the isa server 2004 on domain controller which is already working also as DHCP, RIS, Web and FTP server. Also i have 2 NICs one for LAN & other is for WAN.
LAN NIC:
IP: 192.168.0.1
subnet: 255.255.255.0
Default Gateway: No
Prefered DNS: 192.168.0.1
and WAN configurations are
IP: 192.168.1.2
subnet: 255.255.255.0
Default Gateway: 192.168.1.1
Preffered DNS: Given by service provider
I am using Default Gateway for LAN but after installing NIC for WAN internet not working so i removed default gateway of LAN.
After installing isa server i put following rules
Local Host to External
Internal to Local Host
Internal to Internet
It work properly from client local administrator. i am accessing internet both on domain controller and workstation but my domain user are unable to connect it gives message that “domain controller is not available either you are not connected” all services of DHCP, RIS are not working. ping is also not working from domain controller but workstation properly ping the domain controller.
