How do I reconfigure com ports in Windows NT?

Hi all -

I have a Micron Transport laptop running Windows NT 4.0. Somehow my com ports were deleted, and I'm not sure how. I experienced an error when I attempted to change display settings and the screen was completely blank - everytime I re-booted also. Somehow by loading in the Home profile instead of Office profile I was able to fix it - for the Office profile too. Then I realized something happened with the com ports because they were gone and my modem wouldn't connect. I have tried to re-install the modem using drivers I downloaded from the web (it's a Megahertz modem) and nothing. I tried to re-install ports and used com port settings I found on the web and nothing. The modem says that there was an error connecting to the com port or a hardware failure. I THINK it's just not "connected" to the com port correctly. Please help! How can I fix this? Thank you!!!!!!!!!!!!!!!!!!!!!
