Saving RPC FAULTs
From SambaWiki
In the AD DC, to save packets that give an NDR fault, because they do not have correct IDL:
* Build with --enable-developer * set this in the smb.conf dcesrv:stubs directory = /var/log/samba
Any packet that fails to parse will be written into that directory, with the failure reason.
These can then be given to ndrdump when fixing the IDL.
