Samba4: Panic when joining w2k machine

[Mark Rutherford]

I think... I was joining our only windows 2000 machine about the time 
this event showed up in the log.
The machine also gave me a cryptic error and failed to join.
I came to investigate and saw this, restarted Samba4 and tried to join 
it again and it worked fine.
I can't seem to reproduce it unfortunately.
Regrettably I did not have debug turned up very high so this is all I 
have, and I hope it helps in some way:
If not, sorry about the noise.
