Problem: (Error once to open EMC) The attempt to connect to http://exchange.contoso.com'/powershell using 'Kerberos' authentication failed: Connecting to the remote server failed with the following error message : WinRM cannot process the request. The following error occurred while using Kerberos authentication: The network path was not found.
Resolutions:
Method 1:
Close all MMC/EMC instances before proceeding.
Open Registry Editor (regedit) as the user you run the EMC under.
Go to
HKEY_CURRENT_USER\SOFTWARE\Microsoft\ExchangeServer\v14\AdminTools
Look for value NodeStructureSetting.
If it is there, back it up and then remove it.
Method 2:
Close all MMC/EMC Instances before proceeding.
Open Powershell or Powershell IDE as the user you run the EMC under and execute the following command:.
Remove-ItemProperty -Path HKCU:\Software\Microsoft\ExchangeServer\v14\AdminTools\ -Name NodeStructureSettings
Close Powershell
After performing either of the methods above to remove the registry entry you should be able to open the Exchange Management Console and it will discover another Exchange server and connect.
