SYMPTOMS
If a Windows NT Workstation 4.0 client using the Small Business Server (SBS) modem sharing client dials out using a shared modem on the server and that connection is dropped by the dial-in server, the shared COM (modem sharing) port on the SBS server may not be freed up for use by other modem sharing clients. However, other applications on the same client can continue to access the shared modem. CAUSE
This problem is not apparent until you use modem sharing.
RAS still holds the port open through TAPI, even after the Dial-Up Networking (DUN) session is disconnected by the dial-in server. This means that other TAPI applications (on the same computer) can use the modem. Therefore, this RAS behavior is not a problem if you do not use modem sharing. However, if the modem is a modem sharing modem, keeping the port open means that the port on the server is open, so other computers cannot use it (but other TAPI applications on the same computer can).
RESOLUTIONTo work around this problem, you can do either of the following:
