IPV6 Death

Consider: a peer-to-peer network with only two computers through a common hub.  Everything's working fine; file sharing, ping back and forth, Internet access good...... then comes along a friend who upgrades one of the XP Pro machines over the Internet, and picks up IPv6.  All of a sudden he can't get into his "6" computer (the "upgraded" one) from the other.  When you do an IPCONFIG/ALL, the IP address is displayed along with a ton of other "stuff" relative to the NIC.  After removing IPv6, the other "stuff" is gone, but the former "6" computer can't be reached across the network.  Can't ping its static address, can't see the rest of the network in "Network Places" from it; it's basically isolated.  Anyone know what to do?  Why in the world would something like this be forced upon us at upgrade?  Ernie.

You should be able to uninstall the IPV6 from the upgraded system.

Open Network Connections

Right-click any local area connection, and then click Properties.

Click Microsoft TCP/IP version 6 in the list of installed components, and then click Uninstall.

In the Uninstall Microsoft TCP/IP version 6 dialog box, click Yes.

Click Close to save changes to your network connection.

Once you have that out - add IPv4 - you should be square.
