I have 2 Windows Server 2003 boxes that sit idle, for the most part, on weekends. Yet when I look at my router's DNS logs, both machine's are making many requests for www.yahoo.com when there's nobody using the machine.
None of the programs that run in perpetuity make any requests to Yahoo that I know of. The requests happen at a rate of slightly more than 1/minute.
Is there a way that I can find out which program or service running is making these requests?
