DHCP fails when host is my Windows XP Pro desktop

EDIT:

The solution turned out to that it was a blunder, making this a lot of reading and work that would not be relevant to anyone elses problem, so please save yourself the effort. It was a second firewall installed from the motherboard driver CD that I had forgotten about. When I removed it, everything started working normally again.

Situation:

I have no DHCP provided IP when the host is my Windows XP Pro desktop system, but do when I reboot into a Fedora host.

All hardware is the same.

My VMs have all network adaptors working when the host is Fedora.

But when I reboot the machine into the Windows XP host, the bridged network fails to perform well.

I hadn't noticed the lack of DHCP because I usually use static IPs, but my VMs must work in a Windows mobile environment.

I have experienced some difficulties with other XP hosts, and need to find out if I am missing a setting in some, or if I have a single bad installaion.

The source of the DHCP IP is my Linksys router.

I hooked up a Windows XP laptop and it got a good DHCP IP. Therefore I conclude that the router is not to blame.

This is the ifconfig output from the Fedora host. Note that the DHCP works. Also there is virbr0 (Virtual Bridge 0)

This is the ipconfig output from the Windows XP Pro host.

Note the lack of a DHCP provided IP address.

Is there a setting anywhere in XP that I might not have set correctly ?

It is solved 😮

It was the nVidea Forceware "firewall" that came with my motherboard driver CD.

I have the Sunbelt Personal Firewall on here, which I can configure easily and visibly. But I had forgotten the nVidia Forceware firewall. I have told it yes on most things it asked about, and never told it no on anything to do with allowing DHCP through. But since this situation has been so strange, getting good DHCP with the same equipment and different OS, and continued even when The Firewall was deactivated, something had to give. I decided to deactivate the other firewall that had completely slipped my mind.

And then I did a ipconfig /all, and suddenly I had real IPs from the DHCP server on the router.

And I do thank everyone who has been kind enough to read through all this, and especially to AWo for all his help.
