username.domain local profiles driving me insane

[chrisjako]

Hey folks, I need to call upon the collective powers that be on this forum to try help figure out why Windows 10 logins randomly add ".domain" to a users profile within the C:\Users path

 

Our major issue with this is that our group policy maps known folder locations to c:\users\username\Onedrive\ so when they login and get c:\users\username.domain\ as a profile path they dont get their desktop or documents redirected to the correct location.

 

Onedrive which is setup to SSO on login also crashes out with a 0x8004de40 error

 

We do not use roaming profiles or map home drives, everything in the profile section in AD is empty

 

Now, I know the fix and workaround:

 

1) Log user off

2) Delete folder : c:\users\username.domain

3) Delete registry key machinename\HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\ProfileList\sidnumber

4) Log user back in

5) Close OneDrive and open CMD to run netsh winsock reset catalog - This fixes the 0x8004de40 error

 

However i would like to try get the the route of the problem and try implement a permanent fix so any assistance with this would be greatly appreciated, out of 200 daily logins by staff we have to tackle this issue on average 5 times per day, it's not the same staff and not the same computers the issue arises on so I am ruling out hardware and user account specific probable causes.
