I have upgraded my study computer to an Intel Extreme motherboard and i7 processor, WINDOWS 7 Pro OS, with all the new other little bits necessary.
This is connected to the lounge computer running XP Pro over the network.
The Windows 7 computer can see the XP computer and the C: drive, but the XP computer cannot see the Windows 7 computer, or any of the 11 drives.
All the drives on the two computers are shared.
Before the upgrade, the the study computer was running XP pro with no network problems in either direction.
I have renamed the study computer and changed the network path on the lounge computer.
I have now run out of ideas.Have you checked if Network DISCOVERY and file/printer sharing is enabled in Windows 7?
Hi there Joy. yes, they are both enabled.Did you put them both in the same work group?Try disabling both FIREWALLS.  Does this resolve it?  If so, the firewalls need to be configured to allow file/printer sharing. Quote from: RAPTOR on JANUARY 08, 2012, 05:47:44 PM
