Unable to remove static IP address 2

[njw51]

The problem is on a Windows XP Pro laptop. It was set up to use dynamic IP addresses. Last week, at a hotel, a technician changed it to use a static address. I have changed it back to use dynamic addresses (via Internet properties on the adaptor properties). When the PC is rebooted, the address is back at the static address again, even though it is still set up to use dynamic addressing.

Any thoughts on where the problem might lie?

From a command prompt try:

ipconfig /release
then
ipconfig /renew

what happens?

Sorry, I did try that - still the same IP address.

whats under the advanced properties of your network card, is it set to nothing or is it set to use a specified address?

If that address is present there, remove it, restart and check again.

I can't check now as I can't get access to it until tomorrow morning. Should be set to nothing.

If the above doesn't work, you could try System Restore to a point before the Hotel visit.

One thing that might work is if you go to Device manager and uninstall the network. That might allow you to go back to a dynamic setting. You can also use WinSock XP Fix it's a great little program that has helped me many times concerning NIC problems.

In my earlier post of 'what happens', I was hoping that you'd actually tell us what happens - particularly with the /release command. Does it actually release & tell you that you have an ip address of 0.0.0.0? After releasing, do you get the 'limited/no connectivity warning' in the taskbar?

Problem fixed, along with the removal of a trojan which might have been causing the problem.

smah - I would have liked to have given you that info, but at the time the PC was at the other end of a telephone line, with a non-technical user.

tonycard1170 - thanks for the reference to winsockxpfix - now in my toolkit.

Many thanks to all for the help.

Good to hear you got it fixed. Winsockxpfix is a great program. Glad I could pass on.

ever since SP2 hit the update shelves, a while back, Winsock Fix actually has become obsolete, but still will work...

you can achieve the same with the following command (CLI):

netsh winsock reset
