Error: "Windows could not connect to the Group Policy Client service"

Original title: I have Vista on my home pc and need help

A few days ago when my daughter(8) tried to log in this is the message received "Windows could not connect to the Group Policy Client service. Please consult your system administrator."  Have I done something wrong? I even tried to create a new user account for her and it won't let me!  I have an Administrator account and made her a basic user account without a password, with parental controls and time limits set when we got the computer last October for her birthday.  I have never had any problems like this.  Please help me with this!  Thank you so much.




Have you tried the steps outlined by Diana D?


Method 1:


a)      Log on to the machine as administrator

b)      Click start and into the search box type “Event Viewer” and press enter

c)       Look in the Windows Logs under System for any Warnings or Errors. The error message will be something like Windows cannot process Group Policy Client Side Extension

d)      On the details tab, take a note of the GUID (Globally Unique Identifier) for the faulty client side extension

e)      Click start and into the search box type “regedit” and press enter

f)       Navigate to HKEY_LOCAL_MACHINE\Software\Microsoft\Windows NT\CurrentVersion\Winlogon\GPExtensions and then click on the string that represents your faulty GP Extension.

g)      Click on the file menu and choose export and save a backup of the file.

h)      Once the registry is backed up you can delete the folder that corresponds to the GUID

i)        Do a restart and log on as a normal user.
