Yes, then it does take the hostname. Just be warned, that in such cases the hostname max lenght is 15 chars. 
And it must comply to the netbios nameing rules. 
Thats why i preffer to set it in the smb.conf.

Ok so most probely only villach-dc-bis. 

You need to verify all GUID of the DC's. ( and A/PTR/CNAME records ) 
ldbsearch -H /var/lib/samba/private/sam.ldb '(fromServer=*CN=Windows-DC*)' --cross-ncs dn

Once you have these of all DC's. 
Samba INTERNAL_DNS Back End - Troubleshooting
BIND9_DLZ DNS Back End - Troubleshooting
I forgot which one you used. 

Then lookup the zone:  _msdcs and verify the GUID there, villach-dc-bis probely incorrect, 
at least look like it thats your problem.

Do this on every AD-DC server for every AD-DC, verify all A/PTR and GUID(CNAME) records. 

And most probely one server is 100% correct, execpt the GUID(CNAME) of the villach-dc-bis. 
Fix it on that server, then full replicate the DB again to the failty server. 
Then thats done, reboot the server, no.. Not stop start samba, reboot it.
Then wait 15 min. And re-check your replication.
