The following procedure sets up the Windows for Workgroups 3.11 Point to Point RAS service. 

First get the extra software from Microsoft, to upgrade the existing Remote Access Services Software that comes standard with Windows for Workgroups 3.11. You can get this software from the Microsoft Australian Bulletin Board and most likely on Compuserve. (You can probably get it directly from Microsoft on request.)

Follow the instructions provided with the software to setup and use the software.

The setup is simple but does require a reasonable understanding of Windows networking and Modem communications. Before you start, you should make complete backups of all your windows INI files, and the CONFIG.SYS and AUTOEXEC.BAT files. Check the MODEM.INF file that comes with the Microsoft Point To Point software to see if your modem is supported. If it is not, create an entry in this file as described in the help file that comes with the Microsoft Point to Point Software.

This system has limitations that restrict its usage in a normal LAN setup. The Microsoft Point to Point software is just as its name implies - it will not allow a remote user to communicate with, and share resources with other machines on the LAN. It will only communicate with the PC that you are dialled into. This restriction also means that the remote Citect will not communicate to any other PC's on the normal LAN, nor will the LAN based Citect, communicate with other PC's on the LAN because Citect can only communicate to one LANA NetBIOS stack at a time. (This restriction may be removed in the future.) If you need a system such as this, you should use a hardware system such as the 3Com Access Server, the Shiva LanRover or Windows NT RAS service, see Q1338 for details.

This software is only suitable for a system with a Stand alone Citect station that you want to dial into. You will have exactly the same access and control as the single Stand alone Citect station.
