I just started watching this thread, so I hope I am not repeating
something that has already been mentioned.

This is in WinXP Pro

Open Network Connections
Double-click TCP/IP. This opens properties
Click on advanced in the lower right corner
Click the options tab
Select TCP/IP filtering, then click Properties
Make sure "Enable TCP/IP Filtering (All adapters)" is unchecked.
