I am an desktop tech for a company. I have two machines that updated with windows updates last thursday. One is a laptop and the other is a desktop. Both are dell pc's. The desktop is using comm 1 to connect to the site via modem. The laptop is using comm 1 to sync a palm pilot. What happens is everything looks good in device manager but the devices attached do not work. If I uninstall the comm port in device manager then have windows reinstall the comm port. The devices are able to work just fine. Once you reboot the machines the devices no longer work. As long as the pc's is not rebooted the comm port works as it should. There is nothing in event viewer or device manager stating something is wrong with the comm port. I would be very thankful for any advice on how to resolve this issue.
