- SUMMARY
- =======
-
- A Remote Access Service (RAS) for Windows NT 3.1 server MODEM.INF file will
- need modification in order to allow RAS for Windows for Workgroups 3.11
- clients or RAS for Windows NT 3.1 clients to be successfully authenticated
- if an AT&T BNS 1000 security switch box(or similar device) is linked in
- line between the RAS server's serial port and its modem.

-
- This information does NOT apply to RAS 1.0, 1.1, nor 1.1a, because these
- versions do NOT include support for any kind of dialogue with a security
- host such as the AT&T BNS 1000 switch device.
-
- Please note: The AT&T BNS 1000 device has NOT been certified for use with
- RAS at the time this article was written (November 29, 1993) and Microsoft
- therefore does NOT support it at this time. However, the following
- modifications may be all that's needed to operate RAS with this device
- successfully.
-
- MORE INFORMATION
- ================
-
- If the following modifications to the RAS server's MODEM.INF file are not
- made, the RAS client user will initially be able to connect to the RAS
- server's modem, go into RAS' interactive Terminal mode and be successfully
- authenticated by the AT&T BNS 1000 security device, but then will be
- disconnected immediately after choosing Done in the Terminal mode.
-
- In order for the RAS server to properly wait for the client signal and
- authenticate RAS callers, do the following:
-
- 1. Stop the RAS server.
-
- 2. Copy the [SD ACM400 w/ AT&T 3820] section in the MODEM.INF file to the
- of the file to create a new section.
-
- 3. Give the newly created section a new section title, for example, [AT&T
- BNS 1000 switch] and remove all the comment lines below the section
- title that start with a semicolon.
-
- 4. Remove all the following lines
-
- - macros(for example, "<speaker_on>=M1" and so on)
- - COMMAND_INIT
- - COMMAND_DIAL
-
- and then edit the rest of the section so it looks like this:
-
- ;---------------------------------------------------------
- [AT&T BNS 1000 switch]
-
- DEFAULTOFF=
- MAXCARRIERBPS=19200
- MAXCONNECTBPS=19200
-
- COMMAND_LISTEN=
- CONNECT=<match>"DIALIN_GATEWAY"
-
- ;---------------------------------------------------------------
-
- 5. Save and close the MODEM.INF file.
-
- 6. In the Control Panel window, choose the Network icon, and then select
- Remote Access Service in the Installed Network Software list. Choose
- Configure and reconfigure RAS to use the newly created section in the
- MODEM.INF file.
-
- 7. Restart RAS on the server.
-
- With this new MODEM.INF section, the RAS server will NOT attempt any
- initialization of a modem or other device, but will simply listen and then
- attempt to match the string "DIALIN_GATEWAY" with the information sent by
- the RAS client. The RAS client sends this string several times during the
- initial connection process which allows for a successful connection.
