Hmmm, before that, we are responding to the GETDC wrongly.  We do not
notice that the mailslot is \MAILSLOT\NET\NETLOGON rather than
\MAILSLOT\NET\NTLOGON so we truncate the response, which probably confuses

I have added a check for an NT Version of 0x0B to make sure we send the
correct response.

We will see what that does.
