Question : Network computer disappears

I have set up a small office network (6 computers), 3 with Windows XP and three with Windows ME.  Everything works fine when I start all the computers, everyone can see everyone and get to everyone else's computer through my network places, view workgroup computers, but after a certain length of time (a couple hours) one of the XP computer's icon, the same one each time, disappears from the workgroup computers' view.  I can still ping the computer, it's just that the icon is gone from all the other computers' view.  I've checked the hibernate and it is off on the problematic computer.  500 pts for this question.  Thanks.

Answer : Network computer disappears

Is tricia the one that you ran the Browstat on?  In any case shut down the Tricia machine and reboot all others to see of the machine dissapears again.  Maybe its a problem with Tricia being the Browse Master.
