[geeks] What would cause this

[Andrew Weiss]

OK I did this... the quick answer is that every hour or so there is an 
ARP who-has message going between the Sparc LX out of box Solaris 7 and 
the Win2K machine.  Every time this happens the dialup link is brought 
up... hmmm now what makes this Sparc LX ARP happy?
