Hotfix for Vista ICS

Aaron Tiensivu's Blog: KB 937168 - After you configure Internet Connection Sharing in Windows Vista, the network connection stops working after one-to-two hours.

After you configure Internet Connection Sharing in Windows Vista, you may find that, although the network connection works correctly at first, the network connection stops working after one-to-two hours. For example, you may be unable to connect to the Internet, to other computers on the local area network (LAN), or to network resources on the LAN. .... This problem occurs because of a bug in the WinSock bind() function.

Ran across this problem setting up loopback adapter for VirtualPC to be able to still access internet. Internet access is through cell modem (Sierra Wireless 875U), so cannot use the adapter and get another IP address. Also need to access host-2-guest and guest-2-host without having DNS server, so needed to use loopback adapter.
