From b231d2fafaff8dc67ef2dbaec778f716524d4f6a Mon Sep 17 00:00:00 2001

Subject: - added DCE/RPC "fault" PDU support.

- disabled (AGAIN) the GETDC "if (MAILSLOT\NTLOGON)" code that will get
NT5rc2 to work but WILL break win95 (AGAIN).  this needs _not_ to be
re-enabled but to be replaced with a better mechanism.

- added SMBwrite support (note: SMBwriteX already existed) as NT5rc2 is
sending DCE/RPC over SMBwrite not SMBwriteX.
(This used to be commit 25c70e3c984c4fed19763ed405741e83fe14f87e)
