That error message seems to appear in only one place in the standard 
Samba code:

libcli/util/ntstatus_err_table.txt

Where you will find this (at line 8022):

0xC003000C

RPC_NT_BAD_STUB_DATA
	

The stub received bad data.

I cannot find it anywhere else in the code, this doesn't mean it isn't 
used by Samba, just that I cannot trace any use of it.

I cannot print my thoughts on synology, I would really upset them.

Rowland

Thanks for the hints, I will take a look. Support ticket to Synology is
out, let's hope they respond with anything useful and this is not the first
"signs" of Samba breaking, as it was suggested in the thread you
mentioned.
If there is any solution I will post it here anyways for archival purpose.

I can only imagine. It is all good and easy if it works, but as soon as you
face a problem like this, you waste the effort tenfold, that it would have
cost you, to set it up vanilla in the first place.

Thanks again & have a good one. Kristian
