The office where I work has internet connection via satellite (Bentley Walker's). The internet speed is 512/128 kbps dynamic. The speed decreases according to the traffic load. Right now we have proper internet connection for about 3-4 hours. After that speed drops. We want to connect another assymetric satellite internet connection (with only download option). The office has only one server: windows server 2003 sp1 with isa server 2006 installed. I need that server should always use first inet connection for upload and use both inet connections for download in schedule. For example: Between 7AM to 11AM first ISP after 11AM second ISP. Can ISA Server 2006 do it alone or I need third party software. If I can manage it we are going to try this settings for a while. If the expected internet performance wont be acheived may be we will have to change the settings for using both of them at the same time. But then I guess I will need a router to accomplish it. I am going to set up another NIC for the second ISP to the server. So the server will have 3 NICs. 2 for WAN and one for LAN. Thanks

I would look into a Dual WAN Router instead of using all those NICs.

Do you know , howto setup etherchannel? on a cisco switch? I would use that?
