Few days ago . Our Primary Domain Controller named "PrimDC01.pooja.com" becomes hangs . Upon forcefully shutdown and then start , it stopped functioning properly .While check , we observed that FSMO roles were transferred to additional DC named "ADC01.pooja.com".After that we can add/remove users successfully in AD . Join workstations to AD successfully , however while joining any new Win Server 2008 R2 , its not joining to AD. DNS is not updating/adding records of newly joined workstations .
Exchange Server DAG is not connecting. Cluster Nodes are not communicating with each other. Throwing error of 'authentication problem'.
Emails flow stopped. No email send /receive .
We run AD health check and got this result .
