How to Configure Windows Firewall for NLB

I am running Windows Server 2003 Standard x64 and have two servers in a NLB
cluster. Without Windows firewall enabled they work fine, and I can load NLB
Manager on either machine and it can communicate with and configure both
nodes.

When I turn on the firewall the NLB cluster appears to be ok, but each
machine is only able to configure itself, and not the other node.

What should I be setting in the firewall exceptions to make this work?

Any help appreciated.

TIA

Charles

Let me see that your implementation of NLB is a bit strange.
You should abling the firewall log file when you see all the connection
rejected.
Once you can create the appropriate rules.
