Dear all,

We are have win2k3 SP2 with ISA2k6 SP1 and clients side is WinXP-SP2 all works fine except the internet since few weeks, in our 2k3 server 2 NIC's is intalled one to our corporate internal LAN and second is Internet (ISP), due to some technical prblem from the ISP side i have arrange another backup ISP connection for backup purpose, now the third NIC's is install too in our Win2k3 Server, i want to make both ISP as a primary and secondary purpose, likewise, when our primary ISP goes down due to any technical problem from their own side then automatcally backup ISP take Primary seat. hope anyone can get my point.

Regards

That won't work -- you can install a second NIC, and then disable it. Then if the first NIC dies, you can manually enable it.

HTH,
Tom

Yep you cant, as ISA Server does not support multiple gateways.

what you can do, is to get a router and install it infront of ISA Server, that would support mulitple gateways.

ISP1 ------------
Router ------------ ISA Server ------------ LAN
ISP2 ------------
