Hello HombreUSA, I am also experiencing the same issue. I am also using Sony TP series desktop computer. The computer was fine when I first bought it, As long as I could recall, this problem occured right after I installed 3 month trial Symantec Internet Security 2008 which came with Sony. It installed Symantec miniport on every of my network adaptors. I can't uninstall them, even if I uninstall Symantec program, i still have the symantec miniport in devman. This is driving me crazy. I don't know if this is a antivirus issue or Sony itself. So far, i look over the net, i only found you who experience the same thing.

Let me know if you have this issue resolved. Thanks, I'll keep you posted if I get it resolved.

John,
thank you for helping out. I tried your methods, but doesn't seem to work.
the problem is, you can't uninstall, update drive, etc. I wish it was this simple. The weird thing is, i though my Sony came with Marvell ethernet, but Vista recognize it as Intels... perhaps Vista is causing this conflict. I now have wireless and ethernet driver resolved. but the rest miniport (PPPOe), miniport (PPTP), miniport (6TO4), etc are still having yellow exclamation (code 31) issue. I can't update or uninstall the driver, how can I install a new one if it's already existed. I understand
