NLB not working

We have 2 boxes setup that are part of a Windows Load
Balanced cluster (Windows 2003 Standard). The boxes are
equally weighted and are set up to use single affinity as
this is what our application requires. We are load
balancing on ports 80 and 443.

Unfortunatley for some reason only one of the boxes is
servicing requests despite both boxes being up and
converged in the NLB cluster. If we drop the machine that
is servicing requests the machine that hasn't been will
start to servicing requests.

This is obviously affecting the performance of the
application. Any ideas would be gratefully appreciated.

This is a little bit hard to troubleshoot with this information; Can you
please do a
wlbs display all
on both machines and send the output; also send the out of
ipconfig /all

Are this machines connected to a hub or a switch?
thanks
JC
