No idea where to write this one ... maybe someone can redirect me .

I have a PC that reboots itself no matter what I do. After lot of painfull tests this is what I found:

* The PC does not reboot if the LAN cable is not connected.
* As soon (15/20seconds) as the LAN cable is reconnected, it boots.

An Ethereal trace shows a series of
NBNS Name query NB BRN_6F2D1D<00>
messages just before the PC reboots, coming from diferent PCs on the LAN and directed to 192.168.1.255

This seems to be a request for a shared Brother printer USB connected to the rebooting PC ... but somehow strange because the PC reboots itself even when all other PCs on the LAN are switched off (and of course I cannot get an Ethereal trace in that situation ).

Any idea? Even a forum where this can be posted would help, I don't know how to deal with it.
