Exchange 2010 - EMC connection issue

Client access servers were updated with SP2 UR6. Management workstation where EMC installed was also updated with this Update Rollup.

After updates we got EMC error on Management workstation:
The attempt to connect to http://ExchangeServerName/PowerShell using "Kerberos" authentication failed. Connecting to remote server failed with the following message: Logon failure: unknown user name or bad password. For more information see the about_Remote_Troubleshooting Help topic.

Step 1. Enable and disable RemotePowerShellEnabled for exchange user:

Get-User UserName | fl *RemotePowerShellEnabled*
Set-User UserName -RemotePowerShellEnabled $false
Set-User UserName -RemotePowerShellEnabled $true

Step 2. Hide/Unhide user mailbox from Exchange address lists.

Step 3. Re-install Update Rollup on management station. 

UR was installed by user from different domain with SID history of current user. Issue was resolved by making changes on mailbox (Step 1-2) and reinstalling Update Rollup with right account.
