Hi

I have a 2006 POD with all servers  in a vlan A that all joined to AD A and my Lan production net in Vlan B and joined to AD B. my Vcenter is in domain B so I Configured conditional forwarder on both domain A&B to they can use Vcenter. for about 5 month all works well until to night horizon console shows new issue in dashboard. "domain status error detected. domain can not be contacted"

I have a connection server and a replica and active and connection servers ping each other. what can I do?

Thank you in advance
