We have ipv6 enabled on an XP, but we are not using a ipv6 enabled router.  This is causing some conflict of ip address on this particular pc, so I am inclined to believe it should be disabled.  Going through Control Panel and Network leads me nowhere as it doesn't indicate the ipv6 so I guess I need to use the "netsh" command.
Ipconfig gives me this:
F:\>ipconfig

I guess I should ask:  how do I disable this thing?
Are you using Vista?

Anyway, if you are using IPv6, you should be able to see both versions 4 and 6 listed in the properties of the Local Area Connection. It should look something like this:

Client for Microsoft Networks
QoS Packet Scheduler
File and Printer Sharing for Microsoft Networks
Internet Protocol Version 6 (TCP/IPv6)
Internet Protocol Version 4 (TCP/IPv4)

etc...

You would need to uncheck the checkbox next to the TCP/IPv6 entry. You could also choose to uninstall it, but you may want it sometime in the future.

No, we are not using Vista, and the IPv6 is not indicated under Local Area Connections, that's why I am wondering if it was done via the netsh command.
Do you have a VPN enabled?

>>"IPv6 is not indicated under Local Area Connections"
If you right click on the adapter in the "Network Connections" window and choose properties, under "This connection uses the following items" you should see  "Microsoft TCP/IP version 6" . Highlight it and click uninstall.
Note: make sure you create a restore point, and back up any data, before attempting, I had one system crash after doing so, to the point I had to do a repair install.

What I finally discovered was that the IpV6 had been erroneously uninstalled.  So my solution is to install it again and then run the uninstall, as this is the preferred method of removal.  Thanks everyone!
