SYMPTOMS
You add a modem to one of the COM ports on a Microsoft Windows 2000 Server-based server computer. Then, you open the Routing and Remote Access Microsoft Management Console (MMC) snap-in. When you do this, you see that the modem is listed in the snap-in. This behavior occurs even though the port configuration settings in the snap-in are not configured to detect the modem.

In this situation, if you want to use the snap-in to correctly display the modems, you must first use the port configuration settings to release the modem. Then, you must reconfigure the modem.

Note The snap-in settings that you make are not retained after you restart the computer.
