Well, that would be nice but I doubt it, for two reasons:

1) it has happened on two separate 2K machines, but that's not the big 
issue

2) a tcpdump revealed some substantial error-shouting over netbios.
here comes:

(NOTE, dns.pn-trading.se and pdc.pn-trading.se are CNAMES for 
dl380.pn-trading.se which is 192.168.0.2 = samba PDC)

So, I don't have a clue what's going on, would appreciate some input.
