Network consists of 7 clients. 5 running XP and 2 running Win-7. On a new windows 7 machine in explorer under network all of the computers are visible except one XP machine. All other clients can see this machine. If i go "run" and type in a share path for that xp machine I get the folder and can browse and access. It then actually shows this computer with the others under network. But as soon as I close that window and open a new one it is once again gone.
All computers are on workgroup "workgroup" all on same network. All have shares with Everyone Full Control Permissions.
