Actually. . . .
Network Load Balancing is included in all versions of Windows Server 2003

I'm just not sure how to configure it.  and thats what i'm really wanting to use.

any tips on how to translate those instructions to meet my circumstances would be awesome.

Never fails if I say you can't do something, I will be proven wrong.  :-)  
However, as far as I am aware, Windows Network Load balancing is only available to balance the "network load" over a cluster (group of servers).

"I want to use NLB to use two ISPs" is a wonderful statement, but that's just not what NLB is all about.
If EE allowe the little people like us to create new TA's then Rob or I surely would have made the:
"I'm very excited to get two internet connections on my network, what do I do now?" TA by now.

I vote that you cannot use network load balancing to combine internet connections.

Why is your windows computer directly connected to either connection?
-Windows server makes a very expensive router.

clever routing can be used to separate for example EMAIL in and out from WEB traffic, thus load balancing the connections somewhat, but only on a per application basis.

Hi Carl, does seem like we meet on this question quite a bit.  :-)
looks like I'm going to sell the two BEFVP41's that I currently have and purchase an RV042, seem strange that an entrylevel router can do this, but a brain and routing and remote access can not.. *shrug* I'm going to split the points between RobWill and Abs_jaipur  - thanks for all of your input.

Thanks Jason, good luck,
--Rob

ps- There are 3rd party add-ons that will do it with 3 NIC's and a Linux box, but you have to be quite ambitious.
I don't mind learning, as knowledge is power... but you're right the RVO42 is much easier and quicker (why re-invent the wheel right?) :-)
Thanks again Rob.

Agreed, I don't have the patience to go down that road, that's a good high school project in my opinion. <G> Challenging an worth while, but I don't have the time.
Cheers,
