Thanks for the input.  I just assumed that NLB took the port into account.
I guess that's what happens when you "assume"

These servers do host web pages so we will look at using HTTPMON to monitor
them.  In theory, could HTTPMON also be used to monitor a custom application
in so far as to check if it's listening on a certain port?

Yes, NLB does not control the apps. However there is a utility/service
called HTTPMON which controls the web service:

Sorry for the off-topic question but I'm hoping someone can clear the fog.
We are setting up a system that has two W2K3 servers configured to utilize
Microsoft NLB.  Does the NLB logic to determine if a server is "available"
for connections take into account the port of which the client is trying
to
connect on?  Say they are web servers and the WWW service crashes on one
but the server is otherwise running, when a browser is trying to connect
via the NLB name, is it possible for it to get routed to the server where
the WWW service is down? The same for other custom apps, if it isn't
running on one of the servers and the client tries to connect via NLB name
and port, will the NLB logic try to connect it to the server where the app
is down and therefore has less network connections?
