Symptoms

Assume that you establish a dial-up connection through a modem on a computer that is running Windows 7 or Windows Server 2008 R2. Then, you put the computer to sleep or into hibernation. When you resume the computer from sleep or from hibernation, you cannot establish a dial-up connection through the modem. Additionally, you may receive the following error message:

Error 633: The modem (or other connecting device) is already in use or is not configured properly

Note When this issue occurs, you must restart the computer or reset the modem device to establish the dial-up connection.

Cause

This issue occurs because a flag is not reset after the device state is cleaned up when the computer is put to sleep or into hibernation. Therefore, the flag is in an inconsistent state when you resume the computer.

Note The flag is set when the computer is put to sleep or into hibernation. The flag indicates that the states of various internal structures for the modem device have to be cleaned up.
