I have encountered this Windows bug myself. Here is my own research on the topic:

Microsoft acknowledges this bug: http://support.microsoft.com/kb/819036 Start with downloading their tool and see if it solves the issue.

• Download & install their program.
• Run it from the command prompt from C:\program\Microsoft comdisable\
• Write comdisable /list when executing the program.
• All ports on the computer will be shown.
• Write comdisable /disable COMx where x is the port number.
• Do this for all ports on the computer.
• Reboot.

This should hopefully work as an universal solution.

Alternatively, you can hack in boot.ini but I don't believe this works in Vista/Win 7. I have some app note from Cisco systems describing how to do this. If the above doesn't solve your problem, please let me know.
