I connected two computers with an Ethernet crossover cable but they cannot communicate. One computer runs Windows 2000 and the other Windows XP. Both computers have the network services and TCP/IP protocols installed. Both are part of Workgroup. I cannot assign static IP addresses as Windows 2000 is connected to a cable modem for internet access. The computer that runs Windows 2000 can see the other one but not the shared files. The computer that runs Windows XP cannot see anything. Please help.
