If you need the Windows95 Dialup-Server, there is no need anymore to purchase it as part of the "Plus!" - package !
Just download from Microsoft the last update for Dialup-Networking 1.3.


Configure first the Dialup-Networking using your current version of Windows95 (regardless of its version), configure it for dial-out, then install the upgrade, which 'happens' to install also the Dialup-Server (even if there was no "Plus!" previously installed on your system.

This upgrade also includes the new PPTP, allowing a 'Private Network connection via the Internet', which installs some new drivers in your "Network" configuration:

If you don't need it, delete these additional drivers, just keeping your TCP/IP protocol and the "Dialup-Adapter".
When checking now the menu:"Connections" of "Dialup-Networking":
You got it !
