Fix – Windows could not connect to the Group Policy Client service


There are two places to look in the registry:

  1. HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services this path should containgpsvc key (a folder), which is responsible for service parameters and configuration.  I found that the key was intact, so, you do not touch anything here – just check that the key exists.
  2. HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\SVCHOSTThis is the most important path you should look into, as it must contain the keys and values referred in the key #1.  Below are descriptions what must be present there.
  • There must be Multi-String value called GPSvcGroup. My laptop was missing it.  So, you should create multi-string value named GPSvcGroup and assign it value GPSvc.
  • Next, you must create a key (a folder) and name it GPSvcGroup – this key normally should be there, but, again, it was missin on my laptop.
  • Then open newly-created GPSvcGroup folder and create 2 DWORD values:
  1. First called AuthenticationCapabilities and you must give it a value of 0x00003020 (or 12320 in decimal)
  2. Second is called CoInitializeSecurityParam and it must have value of 1.

Once you complete all steps above, reboot the computer and the problem will be fixed.
