Hi Paul,
Thanks! I appreciate your kind words about my presentation :-)
There are several advantages that RainWall has over the Win2k NLB:
1. The major one is symmetric routing. If you want to have inbound and
outbound fault tolerance, NLB can't fill the bill. You have to choose
one or the other.
2. While you can use HTTPMon, RainWall is aware of all ISA Server
services, and can be make aware of other Win2k network and system
services. RainWall can also be made aware of other network and
non-network services.
3. VPN gateways can be a nightmare with NLB. They work great with
RainWall
4. From the information I have, it costs much less to run RainWall than
to upgrade to Win2k Advanced Server.
There's are lot more cool stuff in RainWall than I had time to go over.
Look for my articles on RainWall at www.isaserver.org in the next few
weeks.
Thanks!
Tom

Tom,
I was very impressed with the presentation that you gave
yesterday with the Rainwall product. The only thing that really caught
my eye in the difference of Microsoft's Load Balancing was that it was
unable to fault tolerent if an ISA service was to fail (without
configuring HTTPmon). My question is: Does the cost of RainWall
justify the cost of having to upgrade a server to Windows 2000 Advance
in order to do Network Load Balancing.
Exactly what is the cost in licensing Rainwall, by the way?
Paul
