Hi JeffNero 

Please refer to this article Sophos SafeGuard Authentication Service is not running, no further action possible! error displayed. Also, check if the Microsoft updates (Microsoft KB4016446 and KB3185319) were installed. Let me know if this helps resolve your issue. 

Note: Do let me know if you see any error while starting the SGN Authentication Service.

Thank you for the reply

This is Windows 10, However even still I verified that:

1.) Forefront is not installed and does not apply.

2.) The registry key was set properly for "HKLM\System\CurrentControlSet\services\SGNAuthService"

So, This article is not very helpful, As I have tried it previously.

Additionally, the two KB articles mentioned are not installed because this is a Windows 10 v1607 Build 14393.1480

Please advise on any additional assistance is appreciated.

Regards,

Jeff

It would appear as if I can manually start the Sophos service after login. Manually via the services app.

What's happening is the service does not respond and time out after 30000 milliseconds and moves on to finish startup. 

However, I cannot get the service to start at startup and then it just doesn't launch.

Well, it appears that the issue is resolved by increasing the Services timeout. as follows:

1. Go to Start > Run > and type regedit
2. Navigate to: HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control
3. With the control folder selected, right click in the pane on the right and select new DWORD Value
4. Name the new DWORD: ServicesPipeTimeout
5. Right-click ServicesPipeTimeout, and then click Modify
6. Click Decimal, type '180000', and then click OK
7. Restart the computer

Hi Jeff,

Thank you for sharing the resolution workaround with us. Am glad that you were able to fix the issue.

Hello Jeff,
