"Could not connect to the System Event Notification Service service"
Hello all, I have a persistent issue across my company's domain I would like some help with please. We are getting one main login error: “Windows could not connect to the System Event Notification Service service”
Occasionally the login error is: “Windows could not connect to the Group Policy Client service”
Other related errors after login: “C:\Windows\system32\config\systemprofile\Desktop refers to a location that is unavailable”
And Windows Aero theme is usually disabled until logging out and logging back in again.
• Only Windows 7 and 8.1 boxes affected, Windows 10 not affected
• Only happens in the morning, once a user gets in they won’t have the issue until the next morning
• Single or multiple reboots will fix the issue until the next morning
• Deleting user’s profile on the local machine and rejoining domain fixed the issue for one user, but not another
• Doesn’t seem OU specific
Attempted fixes

• Rejoining domain
• Group policy update (gpupdate /force)
• Updating Symantec to 14.2.1031.0100
• Netsh winsock reset
