Servers in a NLB, duplicate entries and same MAC Address

Anyone knows if this still works for ePO 5.1?

Yes, this is still applicable. I'll get the KB updated.

Re: Servers in a NLB, duplicate entries and same MAC Address

Thanks, but my problem still seems to excist.

Whenever RDS01 communicates with the ePO Server its managed, but as soon as the agent on RDS02 communicates, RDS01 is then unmanaged.

RDS01 and RDS02 is in the same NLB.

Re: Servers in a NLB, duplicate entries and same MAC Address

That doesn't quite sound like the same thing - in the scenario described in the article, what would happen is that you would only see one machine in the tree at any one time. So if RDS01 communicated first, you would see it in the tree as a managed machine. The when RDS02 communicated, it would overwrite the entry so you would only see RDS02, again as a managed machine. It won't cause machines to change from managed to unmanaged.

Can you confirm exactly what behaviour you're seeing?

Thanks -

Joe

Sorry about the late reply.


Its the exact issue i have as you described so well.

They are both managed, but as they have the same MAC Address, they will just overwrite each other on each agent to server communication

Re: Servers in a NLB, duplicate entries and same MAC Address

OK, that sounds like the same issue then. Please check the article again - I have also updated it to include the correct location for the registry entry on a 64bit OS. (Previously it only had the entry for a 32bit OS, which may be the cause of it not working in your environment.)

As you're on ePO 5 you'll need to use the 64bit entry, and remember to restart the services.

HTH -
