I have installed & configured a 10/100Mbps Ethernet Card but it is unable to connect to the network. I have used similar NIC in past, so no probs with the TCP/IP settings. The network adapter is showing up as "This device is working properly" in the Device Manager, yet it is not getting connected. Even the ping feature is returning "no reply". Any clues? (PS. network is working fine, coz if NIC is replaced with the earlier one, the computer is getting connected) Pls help if this indicates the NIC to be a defective one.

When you change your NIC card you also change your MAC address. Your ISP 's DHCP server is probably refusing to issue an IP address because of this. It is too late to clone the MAC address - so a call to your Internet Provider will be necessary. Tell them what you did and ask them to clear the DHCP - you might have to ask for 2nd level support for this.

To test if the NIC is actually passing traffic, open a command prompt and ping the loopback address: 127.0.0.1
This test will ping the actual network interface on the NIC. You should get four quick replies. If you don't, the NIC is bad.
If you do, double-check your IP configuration. More information would be helpful, such as whether you are using DHCP or static addressing.
Post back and let us know.

I would right-click on it in Network connections, and "disable" then "enable" to force the re-acquisition of an IP address.
Also, disable Norton Firewall during all of this - it's quite overzealous and blocks a lot of legit traffic.
Still no joy? Then download a utility calle Winsock XP Fix on another machine, and copy it to the one with the problem.
Run the utililty, obey it's forced reboot command, and hopefully that will work.
Also, try getting a Realtek 8139 based PCI nic, or
a 3com 3c509 nic - what's great about them is that windows 98, me, 2000, xp and vista have the drivers in their library already - no need to worry about keeping a driver disk handy!
