[Samba] Roaming profile not syncing with the server

[Piers Kittel]

Hi all,

An user queried whether the error "Your profile was not synchronised 
with the server" was a big problem, so I had a look into it.  This only 
happens on one computer, all non-admin users has this problem, the Samba 
admin account don't have this problem.  Looking into the windows error 
log, we get plenty of messages of the below:

Looking up error 1504, there's plenty of references to a bug in Windows 
version 1803, however the problem computer has Windows version 1903.  
Last time I had this problem on a different computer, Rowland linked me 
to an issue with an "TEMP" folder in the c:\users folder causing 
synchronisation problems, however the offending folder is absent on this 
computer.  Looking at the log, this has been going on for about a month.

Any ideas how I can fix this please?

Many thanks for your time!

With kind regards - Piers
