I have a desktop running with Windows XP and the network adapter is Realtek RTL8139/810x Family Fast Ethernet NIC. From couple of days I noticed some small problems with my network hence thought to run PC Doctor to test the connection. While running the same, test got failed itself with the following error message:
“Failed TCP/IP Internal Loopback Test Error Code NC315-5W
Failed Network Communication Test Error Code NC315-1W”
Can anybody please tell me what does that means and how can I fix it? Many thanks for all your helps.
