I have 4 computers on my network. The main one is a WinXP Pro hard wired to a 2wire router. The other 3 are (1)Vista (desktop), (2)XP Home (one desktop, one laptop) all wireless. Here is my problem. I have set up shares on the WinXP Pro and the Vista desktop. I can see all shares and machines from the Vista machine, and from the 2 wireless XP machines. When I try to connect the wired XP Pro, it sees nothing but itself. I can ping the other machines by name or IP address with no problem, but it will not see any other machine. All are on the same workgroup. Discovery is running on Vista, SAP on the XP Pro but no connection. Anyone help?
