RE: Problems configuring Integrated NLB on 2004 Ent Array

Tech-Archive recommends: Speed Up your PC by fixing your registry

You sure can specify the communication IP, here is where it is: Arrays |
(array-name) | Configuration | Servers and right click on one of the server
and go to properties; on the Communication tab you can set the IP for
Intra-Array communication.

Did that registry fix work? I’m not sure it will help entirely for your
situation. If it does not, you would need 3 Nic’s per server, A. External
(with NLB) B. Internal (with NLB) C. Intra-Array
