I have a similar problem:
MacBook 2006 model, XP Home SP2 (upgraded to SP3) after installation.
Networking generally worked. I brought in Safari/Bonjour for Windows, and then networking no longer worked. I've restored defaults up one side and down the other. I've tried Shared and Bridged, with and without DHCP. Currently everything is back to defaults, and all machines, virtual and real, have been restarted multiple times. Running ipconfig (with or without any arguments) returns the helpful result: "Windows IP Configuration"
Occasionally "Repair this connection" is an available choice for the network in the XP Control Panels. Repair returns: "Windows could not finish repairing the problem because the following action cannot be repeated. Failed to query TCP/IP settings of the connection. Cannot proceed. For assistance, contact the person who manages your network." Well, that person would be me, and I have no clue what to do here.
That's on top of the overall headache that moving from PD3 to PD4 turned out to be. The upgrader rendered the VM unusable. The backup it made refused to work with a TimeMachine-restored PD3. So I'm working with a fresh XP install.
This is nuts.
