Exiting environment : Windows Server 2008 R2. I am in the process of migrating to Windows Server 2012 R2. I installed Windows Server 2012 R2 on HP DL380p G8 server. I am able to install role or feature using PowerShell but not via GUI ServerManager.
Now, when I go to add a any role or features using GUI ServerManager I am getting the following errors:
**Failed to open runspace pool. The Server Manager WinRM plug-in might be corrupt or missing**
I did the following troubleshooting already:
- Run WinRM quickconfig which shows the service is running and setup for management.
- Restored WinRM settings: winrm invoke restore winrm/config @{}
- Restored WinRM plugin settings: winrm invoke restore winrm/config/plugin @{}
- Add "127.0.0.1" and "::1" to the IP listen list
- Disabled the firewall
- Ensured the Windows Remote Management (WS-Management) service is running.
- Granted the “Validated Write to Service Principal Name” permission to the NETWORK SERVICE using theADSIEDIT.msc
Following are the errors logged: Event ID 10154
The WinrRM failed to create the following SPNs:WSMAN/xxx.abc.com:WSMAN/xxx
Application and services log Event ID 142
WSMAN Operation CreateShell failed, error code 2150858811
I googled but nothing seems to help.
Any help will be highly appreciated.
