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 --------------------------------- Do you Yahoo!? Yahoo! Tax Center - forms, calculators, tips, and more
