I just tried :-)
Certanly, this machine will be removed from wins database after wins.dat 
load.
But then this machine will reregister and all will be OK.
At least this works with windows 2003 server.
And, as I see, there is no problems with registration during wins.dat 
loading,
process () handle messages first and then packets.

btw, it would be better to have interface for register/unregister names 
instead of dumping and loading wins.dat, but I'm not programmer,
I'm fat and lazy admin with almost no C knowledge ;-)
