I'm hoping someone has seen this before, its driving me crazy. I have 4 servers runnning win2003, 2 of them cannot map com ports correctly inside of terminal services. I cannot find any noteworthy differences between them. When opening up Windows explorer, the local server c-drive will be shown as " Com1 on 'tsclient' (C:) " as if it keeps trying to map a local SATA drive as a com port. A NET USE command reflects this as LOCAL= C: REMOTE= \\tsclient\com1 Troubleshooting via Hyperterminal and a couple other apps give random errors indicating that either the port is unavailable, or in use by another app. Has anyone seen anything remotely close that could point me in any direction? thx, bob.
