- WARNING: Using Registry Editor incorrectly can cause
- serious, system-wide problems that may require you to
- reinstall Windows NT to correct them. Microsoft cannot
- guarantee that any problems resulting from the use of
- Registry Editor can be solved. Use this tool at your own
- risk.

- Summary:
-
- Windows NT and Microsoft LAN Manager Remote Access Service (RAS) can
- provide access to remote clients as if they were on the local area
- network (LAN). If you enable full RemoteListen functionality, all
- systems on the LAN can access the RAS client just as if it were
- locally connected. The following features are supported: IPC, mail
- slots, RPC, named pipes, and NBF/NetBEUI. This article is divided into
- two sections:
-
- - RemoteListen Functionality
- - Enabling RemoteListen
-
- RemoteListen Functionality
- ==========================
-
- Beyond simply connecting to and accessing a remote client, these other
- mechanisms function over RAS: IPC, mail slots, RPC (Windows NT), named
- pipes, and NBF\NetBEUI. The following information describes the
- functionality of the three different settings for RemoteListen:
-
- - All
- - Messages
- - None
-
- Note: You can only set RemoteListen for the RAS server. You cannot
- specify different configurations for different clients.
-
- All
- ---
-
- LAN Manger: messages = all
- Windows NT: RemoteListen = 2
-
- The RAS Server posts an NCB_Listen network control block (NCB) for all
- client NetBIOS names on each protocol bound to the RAS server.
-
- Under LAN Manager, each client has an average of five NetBIOS names.
- This equates to 80 names per protocol (16 ports x 5 names = 80). To
- support this many names, you need to modify the MaxNames parameter for
- RAS and the Names parameter for each protocol that you are using on
- the RAS server.
-
- Under Windows NT, clients have an average of seven to eight names, and
- the RAS Server can support up to 64 ports. This results in an even
- more significant drain on resources than under LAN Manager.
-
- Messages
- --------
-
- LAN Manger: messages = messages
- Windows NT: RemoteListen = 1
-
- The default for RemoteListen is set to Messages. This instructs the
- RAS server to post only the Messenger service-related NetBIOS names
- for the client. This allows them to receive things like print
- notifications and NET SEND commands. This does not allow another LAN
- workstation to create a network session with the remote client as in
- the case of a NET USE command.
-
- None
- ----
-
- LAN Manger: messages = none
- Windows NT: RemoteListen = 0
-
- This option instructs the server to not post any NCB_Listens for
- client NetBIOS names. This reduces the resources consumed and the
- connect time. If you are not concerned with any of the previously
- mentioned functionality, this is the best setting to use.
-
- Enabling RemoteListen
- =====================
-
- To enable RemoteListen, add or modify the RemoteListen parameter:
-
- For LAN Manager
- ---------------
-
- 1. Open the LANMAN.INI file on the RAS server in a text editor.
-
- 2. Find the [RemoteAccess] section and add the following line:
-
- remotelisten = <all, messages, or none>
-
- For more information, see the LAN Manager "RAS Administrator's Guide."
-
- For Windows NT or Windows NT Advanced Server
- --------------------------------------------
-
- 1. Start Registry Editor and go to the following subkey:
-
- HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services
- \RemoteAccess\Parameters\NetBIOSGateway
-
- 2. If you can find a RemoteListen key, choose Edit Value from the Edit
- menu and change the value to 2. If there is no RemoteListen key,
- choose Add Key from the Edit menu and use the following
- information:
-
- Value Name: RemoteListen
- Data Type: REG_DWORD
- Value: <0, 1, or 2>
