Applies To: Windows Server 2003, Windows Server 2003 R2, Windows Server 2003 with SP1, Windows Server 2003 with SP2

To install an unsupported modem

  1. Open Phone and Modem Options in Control Panel.

    If you are prompted for location information, enter dialing information for your location and click OK.

  2. On the Modems tab, click Add.

  3. In the Install New Modem wizard, select the Don't detect my modem; I will select it from a list check box, and then click Next.

  4. Do one of the following:


    If Do this

    A modem is listed that is a good match for your modem

    On the list of modems, click the manufacturer and model that is the best match for your modem, and then click Next.

    Your modem is not listed, and you have an installation disk or .inf file provided by the manufacturer

    Click Have Disk and specify the location of the disk or .inf file.

  5. Follow the remaining instructions provided by the Install New Modem wizard.


  • To perform this procedure, you must be a member of the Administrators group on the local computer, or you must have been delegated the appropriate authority. If the computer is joined to a domain, members of the Domain Admins group might be able to perform this procedure. As a security best practice, consider using Run as to perform this procedure.

  • To open a Control Panel item, click Start, click Control Panel, and then double-click the appropriate icon.

  • If possible, get the latest installation disk or modem .inf file designed for your operating system from the manufacturer. This can usually be downloaded from the manufacturer's Web pages. If the installation files for your operating system are unavailable, you can try using an installation disk or .inf file for Windows 95, Windows 98, Windows NT, Windows 2000, Windows Millennium Edition, or Windows XP. It may work correctly in the Windows Server 2003 family as well.

  • If no installation file is available for the modem, the manufacturer's instructions that came with the modem may specify a compatible modem. Otherwise, click (Standard Modem Types) in Manufacturers, and try choosing the standard modem with the speed matching your modem.

  • If a cable is not provided with an external modem, refer to the manufacturer's instructions for cabling requirements. Most but not all off-the-shelf cables will work. Some cables do not have all the pins connected. Do not use the 9-to-25 pin converters that come with most mouse hardware, because some of them do not carry modem signals.

Information about functional differences

  • Your server might function differently based on the version and edition of the operating system that is installed, your account permissions, and your menu settings. For more information, see Viewing Help on the Web.
