Error Message:

The modem (or other connecting device) is already in use or is not configured properly.

Explanation:

If this is a dial-up connection, the COM port that the network connection attempted to use is already in use by another active network connection or another process (for example, a phone line monitoring program, such as a fax program).

User Action:

Quit the application that is blocking the use of the COM port. If this is a virtual private network (VPN) connection, the VPN device that the network connection attempted to use cannot be opened. If the problem persists, see your system administrator.
