Why won't windows connect to the group policy client?

I FOUND SOLUTION TO THIS PROBLEM!

You did a great job on discovering the events BEFORE the issue started to occur.  I had this issue on my laptop since November, and it really bugged me.  Like you, I sifted through the event log and found absolutely the same pattern you described.

In short, the pattern is as follows: Windows updates run automatically, and when reboot is initiated after the updates are finished, the computer crashes.  When it boots up, it reports that the last shutdown was unexpected, and the issue begins to occur.

I spent 2 days trying to dig out a solution from the Internet, to no avail, until I came across this page.  It doesn't say anything about this particular problem, but it gives more information about SVCHOST process that starts many services, including Group Policy Client.  It looks like during reboot a vital registry settings were lost and Group Policy Client simply "doesn't know" how to start. Let me explain:

There are two places to look in the registry:

1. HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services this path should contain gpsvc key (a folder), which is responsible for service parameters and configuration.  I found that the key wasintact, so, you do not touch anything here.
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
• 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 completed all steps above, reboot the computer and the problem will be fixed.

I am so relieved I was able to fix it, and hope this will help others with the similar issue.

I'll 3rd or more this as the fix for this issue!

As a techsupport guy for a living, I can only imagine the pain required to find this solution! 

I'm guessing it went something like this: Export chunks of the Registry for both a working and broken example, use Notepad++ to compare the two text exports, sort thru the piles of perfectly normal differences. 

For those that run into this problem as well (and are brave) Copy the text below and paste into notepad, save as GPSvcGroup.reg (or whatever name you prefer), then merge into registry.

Windows Registry Editor Version 5.00

[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Svchost]

"GPSvcGroup"=hex(7):47,00,50,00,53,00,76,00,63,00,00,00,00,00

[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Svchost\GPSvcGroup]

"AuthenticationCapabilities"=dword:00003020

"ColnitializeSecurityParam"=dword:00000001

Perfect.... Just the info I needed... Thanks!
