- TITLE :How To Demonstrate Windows NT Network Features w/o a Network
- PRODUCT :Windows NT
- PROD/VER:3.10
- OPER/SYS:WINDOWS
- KEYWORDS:
-
- --------------------------------------------------------------------
- The information in this article applies to:
-
- - Microsoft Windows NT operating system version 3.1
- - Microsoft Windows NT Advanced Server version 3.1
- -------------------------------------------------------------------
-
- Under Windows NT and Windows NT Advanced Server, if there is no
- network adapter in the computer, the network services will not start.
- This behavior is by design, because many of these services would be
- useless without a network connection through the network adapter.
-
- If you want to "fool" Windows NT into thinking a network is present,
- for example, when you want to demonstrate the network capabilities of
- Windows NT without being connected to a network, you can install the
- MS Loopback Adapter driver in the Network application in Control
- Panel. This driver allows the computer to connect to "network
- resources" that are actually local. This feature is particularly
- useful for demonstrating applications such as SQL Server for Windows NT
- at events and trade shows.
-
- The MS Loopback Adapter can also be used to enable a standalone
- computer to generate UPS Shutdown messages. The Windows NT "System
- Guide" states that the Alerter and Messenger services must be started
- for a computer to generate a UPS alert. These services will not start
- without a network adapter present. Installing the MS Loopback Adapter
- allows the Alerter and Messenger services to start on a standalone
- system.
-
- The MS Loopback Adapter driver supports the following frame types:
-
- 802.3 (Ethernet)
- 802.5 (Token Ring)
- FDDI
-
- When you install the MS Loopback Adapter driver, the following key and
- subkeys are added to the Registry under
- HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\:
-
- Loop
- Linkage
- Disabled
- Parameters
- TCPIP
-
- The only user-configurable parameter is the frame type, as described
- above.
