It all sort of depends on how many clients you have, if you only have a 
few, then it will probably be easier to start again, but if you have a 
lot, then you need to try and fix it first. You can backup the samba 
databases, see here:

Problem is, what if the databases are already corrupt ?

I would tend to think that something changed between 4.0.4 and 4.1.19 
and that change is now giving you problems. There will have been many 
changes between the two versions and it will be a major task to trace 
the change (it may in fact turn out to be a change on top of another 
change), it is for this reason it is recommended to upgrade often, then 
problems can be addressed whilst the changes are still current.

You may be able to get out of your troubles by adding another DC to 
replace the upgraded one.
