Winlogon 6003 error

[SuperduperPackager]

We are experiencing a weird problem on our Windows 10 machines, would really appreciate some help.

When trying to login, we occasionaly get this message, the login fails and we get taken back to the login screen. If we try again right after, it works.

 

 

In the event viewer, we get this:

 

 

 

At first we thought it might be related to the power management for the network card but we still get the error even after disabling it.

 

 

 

We built a testbench and had 8 computers with autologins loop for a day (thats like 5000 logins) and we didn't get the problem once. But if we leave the same 8 computers at the login screen over the night, we get the error when we login in the morning on a couple of computers.

 

Any idea?
