MTP Problems - My Phone Won't Connect To My Computer Via USB

I have a problem that's unique to a single computer here. When I connect my phone to the comupter via USB, it goes through the Found New Hardware wizard, correctly identifies the phone and fails with the message "The specified service does not exist as an installed device." The same phone connects to other computers here, both XP and Win7. It's just this one computer that has a problem. The computer can connect to external USB thumb drives, hard drives, and optical drive, just not this phone. So I know that the phone is OK and basically the computer is OK.

I've been searching the web for solutions for about a week now, tried everything including a fresh Windows installation and even installing Media Player 11 as recommended by some (I think this may have to do with synchronizing a music player rather than connecting to a generic storage device) and still no go.

Does anyone have any idea what the "specified service" that does not exist is?

The only small clue that I have is that when comparing the running services between a computer that works with the phone and the one that doesn't, the one on which it works has one service started that the other computer does have - it's not even on the list so I can't even turn it on to try it. This is "Windows Driver Foundation - User Mode Driver Framework."

Getting this to work isn't a life-or-death situation, it just bugs me that I can't figure out what's wrong.

I guess I should have expected an answer like that straight off. Of course I went to the web site.

I contacted their tech support and they told me that there were no special drivers needed, that the drivers that the phone uses are from Microsoft and are part of a standard Windows installation. Here's a screen shot of the Windows Device Manager with the phone connected, showing the drivers that are being used. Those two files, wpdusb.sys and wudfrd.sys are also present and in the same location (the windows\system32\drivers folder) on the computer that doesn't seem to be able to associate the device with those drivers.

I thought I had a clue in that when I try to install the drivers manually ("have disk") the .INF files for those drivers are nowhere to be found on the machine. But when I went looking for them on the computer that the phone connects to, they weren't there either. What should I be looking for in order to tell Windows which driver to use with the phone?

It's working with three other WinXP systems here, all with Service Pack 3. Of course I've tried different ports.
