1 Win 7 unit , 1 XP unit connect via a workgruop LAN.
All works fine then the Windows 7 losses access with the XP unit.
(XP unit still see's Win7 unit). Win7 unit can still access the XP unit via a remote control program i.e. It can access the XP's screen, cursor etc. Have unticked the "let computer switch off lan card to save power" and even tried a different card. Have run with dedicated IP address's and "obtain IP automatically"
Run the TCP on version 4 , have ticked and unticked TCP 6
Really need advise as the Win7 units needs to connect to the XPunit to backup every few hous or so. TIA
