Hello folks,

The network team is upgrading the network load balancer and they will change the IP address about the NLB,

Do you know if this will affect the configuration that we have between the MM and the exchange server?

I checked the VMSC and the MAS server is using a hostname for the peer mail (This host name is the hostname related to the NLB IP).

So I think if they just change the IP without changing the name I wont need to do nothing about it.

Please let me know your comments,
Kind regards
Goku


 
It should not but you may need to restart the MAS service if you get 1239 errors.

Goku... is the IP the only change being done? You are not changing from an Exchange 2007 to Exchange 2010 are you?
 
I have had issues in the past when a NLB was added.

I found the following:

Avaya Product Support Notice (PSN) 3514u1, but a search now finds nothing.

The basic fix was to edit the host file on the MAS. Enter the FQDN of the NLB, but put the IP Address as the peer exchange server.

this fixed my issues.
