Very strange then if they where all created clean.
removing and re-adding is possible, but not without rist.

Yes and no. ;-)
I suggest the following, move fsmo roles to villach-dc and check database replications.
Remove the most faulty one first, graz-dc-1b, from the domain. ( check and cleanup DNS and AD! Very important )
You dont have to reinstall the complete os, just cleanup as told, and reprovisioning that server again.
Reboot and then wait, and check database replication again.
! Do reboot !
And repeat for all servers you dont trust.
That should bring you network back as it should be.

No, and yes, but i preffer no, not needed (yet).
Start with the keytab cleanup
Check the dns record if the uuid A PTR and hostnames resolve to the correct server.
If thats the case, then no, cleanup of keytab is, i think, sufficient.
Yes, if its really a mess. ;-)
Then, first a an new DC, then remove, just make sure you always have 2 dc's up and running (correctly)

Ok, now, im out of office in about 10 min, but mail that subject for me again.
I'll have a look.
Own and if you dont use it, ApacheDirectoryStudio can help a lot with cleanup of these kind of things.
But just make sure you know what you delete, for you mess up the AD even more.
