First, if you are going to sanitise your dns domain, please do it
everywhere, otherwise it gets confusing. I take it that
'praxis.domain.tld' is really 'praxis.dr-ts.de'. If this is the case,
then there doesn't seem to anything wrong on the Linux side, apart from
the 'dns forwarder' on the DC, that appears to be forwarding to itself,
when it should be another dns server outside the AD domain e.g. googles
8.8.8.8

Your problem appears to be on the Windows machine, it shouldn't be
using the fritzbox at all, it should be using the Samba DC, you need to
find out why this happening.

Or to put it another way, it's the DNS.
