Wildly excessive DHCPREQUESTs

[John Hascall]

We have a number of machines here which are making a stupidly
high number of DHCPREQUESTS (and DISCOVERS in some cases).

For example, we have a few dozen machines making in excess of
1000 REQUESTs per day.   The worst seems to be an XP box making
about 11,000/day.  Does anyone have any idea what might make a
box do a DHCPREQUEST/ACK cycle about every five seconds all day,
day after day (despite getting a 4 day lease)?
