nmbd & netbios name -> many addreses

Thanks for continuing to dig.  I don't think any of us have had the time 
to put together a system for reproducing this.

So, nmblookup gets the same list from the NT WINS server as it does from 
the Samba NBNS server...

Which is good...

Urg.  The problem is in NT, then.  I think that this is what Jeremy was 
trying to tell us.

Has anyone tried W/9x?

Dangerous.  The two name spaces are *very* different and do not intersect. 
I've worked with this issue for well over a year now and I feel very
uneasy about even suggesting a mapping between the two.

I'd still like to see someone reproduce this in another environment, for 
the reasons that Peter outlined.
