My computer is connected in a LAN with two network adaptors for a purpose. This is working fine for last couple of months. Now, I want to change IP address of one nic when am doing this my computer getting hang.

I tried reinstall of nic driver.

can anyone help?

You have not mentioned the method you are using to accomplish this change, and it will likely prove very difficult for anyone to identify the cause of the hang up without more detailed information.

I am not at all familiar with this kind of change, since my networking experience is limited. However a search found this link which might be helpful to you.

The same search found other possible sources of information. Try [ change nic "IP address" ] or similar for your search term.

Thank you for the link, which will solve my another problem.

Am using Windows XP Professional.

I just doing open network connections ->in this selecting Properties of network adaptor to which IP has to be change there getting the problem as I mentioned.

also I tried Repair option too

plz look into this

You are making me guess what you are doing and why - but I'll try, just a bit.

Some people set up their machine so that one NIC is used to interface with their DSL modem or other connection to the outside world, and a separate NIC is used to connect with a LAN.

In such a setup, the second, LAN oriented NIC may have IP protocol enabled - but that would not be my preference. Ordinarily, I would not be using the IP protocol on my internal lan, but would use the Microsoft Networks or MS file and priter sharing facilities. Accordingly, I have never setup IP addresses for a LAN, and cannot tell you how to do so, if that is what you are attempting to do.

So.... I will guess that you have a machine setup with separate NICs to interface with separate connections to the internet and the outside world. You may be doing that at different times, or perhaps even simultaneously. I do not know how well Win XP will respond to any attempt to use two connections to the internet simultaneously, or if that will freeze XP.

If you are using two NICs to interface with internet connection devices serially - that is at different times - then I see no reason it would not work. The separate NICs would give you distinct MACs for your connections and that could be useful for some purposes.

If you follow procedures such as the following to change the IP addresses for the DNS servers used by each of the ISP's to which you are connecting, and through which you are accessing on the internet, then I do not see why you would have a problem.

To Change / Edit IP addresses

1. Click START menu > CONTROL PANEL > NETWORK and INTERNET CONNECTIONS.
2. At the "Network and Internet Connections" window, click on NETWORK CONNECTIONS, right-click on your "Local Area Connection", select PROPERTIES, highlight "Internet Protocol (TCP/IP)", click on PROPERTIES
3. In the "Internet Protocol (TCP/IP) Properties" window,
* Select "Use the following IP address"
* Enter IP Address: (assigned)
* Enter Subnet Mask: (assigned)
* Enter Default Gateway: (assigned)
* Select "Use the following DNS server addresses"
* Enter Preferred DNS server: [ipaddress]
* Enter Alternate DNS server: [o[address]
* Click OK.

So - are any of these possibilities related to what you are doing? Try not to keep us quite so much "in the dark", eh?

There the problem actually is,

am using the same method too..

1. Click START menu > CONTROL PANEL > NETWORK and INTERNET CONNECTIONS.
2. At the "Network and Internet Connections" window, click on NETWORK CONNECTIONS.
3. right-click on your "Local Area Connection".

at the step -3 my system getting hang.

I mean to say when I right-click on "Local Area Connection 1" or "Local Area Connection 2" (as am having 2 nic's) my computer hangs.

Please confirm that you are signed on as an administrator for this machine when attempting this change.

Although attempting to make this change when not logged on as an administrator should simply fail, and not hang your machine, it is possible that the machine could hang when attempting to issue the error message.

If you are signed on as an admin, and the error occurs, then make a complete record of the settings for each NIC.

Try the following. Uninstall the NIC you are attempting to change. Reboot, and let Win XP find and reinstall the hardware. During the reinstall, establish the settings you desire.

If that does not work you might want to try it for both NIC's.

You have still not provided information about what services you expect these NICs to support. At least one must link to the outside world, the internet. It might be very useful if you would say what each of these NICs is supporting - Local and internet, local only, or internet only. It does make a difference.

Is this machine the machine you are using to access the internet?

If the reinstall fails, you will no longer have access to the network - local or internet - that the NIC is providing the interface for. So be very careful about how you do this, keep good records of the settings you have, the ones you want, and the steps you take in the procedure. Be very alert to the instructions presented on the screen, and follow them after careful consideration of their meaning and consequences.
