Error: 'You have attempted to login with no valid computer ID. This can be due to WMI corruption.'
You can run the following to repair your WMI database.
1. Open up a elevated (admin) command prompt.
2. Disable and stop the WMI service with the following two commands
sc config winmgmt start= disabled net stop winmgmt
3. Run the following commands to repair the database:
Winmgmt /salvagerepository %windir%\System32\wbem Winmgmt /resetrepository %windir%\System32\wbem
4. Re-enable the WMI service and then reboot the server (!!IMPORTANT TO REBOOT!!) and try to login.
sc config winmgmt start= auto
This error can still occur if you are running a virtual machine that does not have any IDs associated to hardware, and cannot be solved through normal means. You REQUIRE an ID to login!
