1. Be sure in XP that the name of the Workgroup is "WORKGROUP". (Right-click on "My Computer," select "Properties." The default workgroup name for XP is MSHOME. Click the "Change" button next to "To rename this computer or to join a Domain." If it is anything but "WORKGROUP" for the workgroup name, rename it to this.) If you change anything, restart the computer.
2. Change encryption on the Win7 machine to 40 or 56-bit. (Open "Start" menu, click "Control Panel," under "Network and Internet" group, select "Choose homegroup and sharing options," then find "Change advanced sharing settings." Now scroll down to "File sharing connections" and change it from 128-bit to 40- or 56-bit)
3. If this doesn't work, look one more setting further down from the last and choose "Turn off password protected sharing." Note: this should only be done on Home or Work, never Public networks. (If you scroll all the way down and see "Public" with a long line and a downward pointing arrow, then you're doing it right).
Try these and see if any of them work...
But are you saying the name of the workgroup could affect it's functionality?? That seems.... odd.
