Please help out with this issue.
Mail are not dropping from inside or outside the network.
I tried to open Exchange Management console but can't open it instead some random initialization failed error messages would popped up,e.g kerberos authentication failed, WINRM couldn't complete the operation.
I checked the event logs and I found error relating to Microsoft Exchange active directory topology service, and I tried to restart the service but the service can't be stopped and all other services control by miscrosoft exchange active directory topology,as they are all stopped, can't be started.
Please note that I have deleted nodestructuresetting in registry editor, this didn't resolve the problem.
