Subject: [unisog] XP silently configuring ad-hoc wifi networks

As all of the students wander onto campus this year, we've been noticing
that a lot of them have common ad-hoc SSIDs configured as a preferred
network.  So far, none of them admit to having any idea how those networks
got configured or where they came from.  While it's quite possible that the
users told Windows to connect without realizing or just without remembering,
this has made me curious.

Does anyone know of any circumstances under which an XP system might attempt
to connect to a previously unconfigured ad-hoc SSID without any user
