After patching a number DAG nodes with SP2 I was unable to open the EMC from any of the mailbox servers.
The follow error was displayed
To resolve this issue I downloaded the Exchange Management Console Troubleshooter Tool EMTShooter
After running the tool it found an error and displayed the following
After reading through the possible solutions I discounted options 2 & 3 as these had already been investigated and the settings were correct.
So with that I settled on option 1.
After examining the GlobalModules of C:\Windows\System32\Inetsrv\config\ApplicationHost.config I could see that the entry for WSMan was indeed missing
I added the entry and closed the file
Refresh the EMC and viola, good as new.

Received a call from a customer this evening regarding complete loss of access to their SAN.
The customer was running a virtual infrastructure and all their VMs were hosted on the SAN, naturally this wasn’t a good situation to be in.
After looking at the SAN it was apparent that the primary datamover had failed over resulting in loss of access to all the vSphere hosts.
Luckily this was a fairly straight forward situation to resolve.
The resolution was thus.
- SSH to control station
- “nas_server -list” to check whether there is a datamover failover.
- “/nas/sbin/getreason” to check the status of the datamovers. The 2 datamovers should be both in “contacted” status.
- “server_standby server_2 –restore mover” to failback the datamover.
- Run “/nas/sbin/getreason” several minutes later to make sure both datamovers are in contacted status.
