AD Computer Account Password - Expiring?!

Dear All,

 

We have installed and have been running vCenter Heartbeat for a while now but we have a problem that I'd appreicate some advice on.

 

It appears that after a while the computer account password get's changed on the primary node, and the secondary node is effectively kicked off the domain - can't log on, can't start the vCenter services...

 

Are we doing something wrong here??!

 

Thanks

That sounds as if both nodes have the same ID in AD (SID, NetBIOS name). Where they cloned?

Regardless of the VMware stuff or what you running on any Windows box, as soon as two machines are member of an AD they must have a different identity. That means a different NetBIOS name and SID. What has happend is that one host changed the secure channel password between DC and member server and the other one didn't (can't) know about that and lost the connection thereby.

 

Having two vCenter server doesn't mean you have to clone the base OS. Only vCenter gets installed twise and the second installation becomes themirror of the first one.

 

Ever read this http://pubs.vmware.com/vsp40/install/c_install_vc_client.html ?

In the Heartbeat doco (http://www.vmware.com/pdf/heartbeat_55_reference_guide.pdf) it states +"The clone must be 100% with no

changes to the Name, SID, or domain membership."+

Ah, O.K., didn't know that....but it seems that both were online once. That might have caused this.
