Windows 2012 R2 Remote Booting Black Screen With Command Prompt Only

If you ever find yourself in a situation where Windows Server 2012 R2 decides to spontaneously switch from regular GUI Windows to Windows Server Core, here’s how you switch it back.


Dism /online /enable-feature /featurename:Server-Gui-Mgmt /featurename:Server-Gui-Shell /featurename:ServerCore-FullServer /all

The command will take a while, but when it is complete all your GUI goodies will return. After a reboot and a long wait you will get your Start menu back!

Group Policy Update Error

ERROR :

C:\Windows\system32>gpupdate /force
Updating policy...

Computer Policy update has completed successfully.
User Policy could not be updated successfully. The following errors were encountered:

The processing of Group Policy failed. Windows attempted to read the file \\BirlasoftCOE.com\SysVol\BirlasoftCOE.com\Policies\{8E6E766D-476D-4422-ADB9-5936C3E89479}\gpt.ini from a domain controller and was not successful. Group Policy settings may not be applied until this event is resolved. This issue may be transient and could be caused by one or more of the following:
a) Name Resolution/Network Connectivity to the current domain controller.
b) File Replication Service Latency (a file created on another domain controller has not replicated to the current domain controller).
c) The Distributed File System (DFS) client has been disabled.

To diagnose the failure, review the event log or run GPRESULT /H GPReport.html from the command line to access information about Group Policy results.
