Hello,

I am using NLB to load balance two servers on my DMZ. My firewall reports
port 135 is being blocked when I attempt to query or setup NLB using the NLB
Wizard in Windows 2003.

How do I disable NLB from using Port 135 to discover the hostnames of the
servers in my NLB cluster?

Thanks,
D

Since you are trying to run a process on another machine (or machines),
you are probably using RPC. RPC uses port 135.
