Unknown devices?

Hi, i recently a new pc running on windows vista, but i had really bad reliability issues, so i reformatted and went back to XP, but now i have a couple of devices in my device manager that have yellow exclamation marks next to them.

The first is terminal server device redirdctor

The scond is an unkown device.

When i go to properties, adn then the details tab, there is ROOTMS_PTMINIPORT%26#65533;000

Any idea on how to get drivers for these things?

ThanksThe motherboard is an ASUS m2npv-vm, the graphics, sound, lan e.t.c have been installed sucesfuly. Unknown devices?
You probably didn't install all the chipset drivers for your motherboard. The MINIPORT typically refers to the USB hub for example. Unknown devices?
OK, i will check that out, any idea on the other thing?
I installed the chipset drivers from the asus website, it wasn't any of those.I was thinking, the mobo has onboard graphics, could it possibly be that i have not installed the drivers for those and therefore it's counting it as an unknown device?Any ideas on what the other thing is?
Chipset drivers wouldn't include the ethernet port and other hardware built into your motherboard. I have an ASUS board, too, and every time I reinstall, I have lots of yellow exclamation points until I get ethernet and RAID and so forth drivers installed. Do you have the disks that came with the motherboard?
