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.
