Help File: iTunes Lockups; Wireless Router Maintenance
Q My Windows XP machine will run fine for days until I start up iTunes to serve up music for my Apple TV. Then it's only a matter of time before the whole system locks up.
A This reader managed to figure out a solution to this problem before I could; several weeks after his first e-mail, he wrote back later to report the fix he'd found.
In this case, iTunes' habit of automatically looking for new Apple TVs on a home network was at fault. Once he'd set up a wireless media receiver in his living room, his copy of iTunes no longer needed to look for other Apple TV units -- but when it did, it sometimes locked up his entire XP system, for reasons still unclear.
