RPCNetlogon provides workstations, member servers and trusted domains with access to the centralised, shared authentication database in WinNT networks. This protocol also includes NT4 level synchronisation of user accounts between a PDC and BDC, as well as many other services.

Protocol dependencies

Example traffic

XXX - Add example traffic here (as plain text or Wireshark screenshot).


The RPCNetlogon dissector is partially functional. There are still a number of unknown commands and feilds.

Preference Settings

(XXX add links to preference settings affecting how RPCNetlogon is dissected).

Example capture file

XXX - Add a simple example capture file to the SampleCaptures page and link from here. Keep it short, it's also a good idea to gzip it to make it even smaller, as Wireshark can open gzipped files automatically.
