can't do that, because the WinHTTP WebProxy Auto-discovery service will be stopped also hence internet access will cease from IE7 since it relies on webproxy server.

any other idea?

Putting the MAC address of the ISA server into the DHCP didn't fix my issue because the ISA server keep leasing new ip address until my DHCP server runs out of ip.

There's got to be a way to stop my ISA server from obtaining new lease.

keith,

ISA is configured with static ip.

From VPN console in ISA, I enable the Static address pool with valid ip address ranges instead of relying on DHCP to supply ip to vpn clients. After doing this, the issue was resolved.
