Chapter 4: Installing the Software

CAUTION

If a Windows NT Service Pack was installed on the system after the first Windows NT installation, you must reinstall it before restarting the computer. For installation information, see the latest available version of your Service Pack help. If you do not reinstall the Service Pack, the Remote Access Service will probably fail to start, or will not behave correctly when connecting ISDN lines.

To determine whether a Service Pack is installed, see Index of Common Tasks on page 115.

8.If the system is a Windows NT basic system, with no service pack installed, click Yes to restart the computer.

Otherwise, click No. Then reinstall the Windows NT Service Pack before restarting the system.

Next, continue the software installation by checking the ISDN line, as described in the next section.

Checking the ISDN Line with LoopTest

After you have installed and configured the adapter software and restarted Windows NT, you can check your ISDN line using the LoopTest utility. This utility calls itself and establishes two ISDN B channels. One of the channels is set to listen, and the second channel calls the first one.
