NLB and Port 135

[Guest Derek Da Silva]

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.
