My network server can't access a new client notebook. The server runs Windows 7 32-bit and the notebook Windows 7 64-bit. Other clients on the network, including a desktop running 32-bit Windows 7, can access the notebook, and the notebook can access the server. I've tried changing ownership of the disc, including by logging on with the default administrator account, but access is denied. I've tried assigning full privileges to Everyone, but access is denied. Please advise.
