I have an issue that has been bothering me for a while on new 8.1 computers. Standard users are not able to log into the computer on the first try consistently. They receive the error message: Group Policy client service failed the sign-in access is denied. They are stuck at the logon screen.

If an administrator logs in (local or domain), they can log in but get a black desktop with two error messages. The first is Location is Not available - C:\Windows\system32\config\systemprofile\Desktop is unavailable. The second error message is a popup balloon. It states "Failed to Connect to a Windows service. Windows couldn't connect to the System Event Notification Service service."

When a standard user attempts to log in, event viewer records three warnings. They are listed in order from oldest to newest

The winlogon notification subscriber <Profiles> was unavailable to handle a critical notification event. -Logged 9:14:44

The winlogon notification subscriber <GPClient> failed a critical notification event. - Logged 9:14:44

The winlogon notification subscriber <Profiles> was unavailable to handle a notification event. - Logged 9:14:49

After a reboot, users still have the issue. I noticed that the user profile services and system event notification service are not running though their startup type is automatic. They start after a minute or two.

I think I found the solution. There was a video driver update for the Intel HD Graphics 4400 that addressed this problem. So far - we've been good. Thank you for your help in resolving this!
