Dial-Up Networking Upgrade 1.2 for Windows(95 Introduction The Windows(95 Dial-Up Networking 1.2 upgrade is a significant enhancement to the Dial-Up Networking features that were originally delivered with Windows95. This upgrade provides client support for a single PPTP connection, support for internal ISDN adapters, multilink capabilities, connection-time scripting to automate non-standard logins, and improved performance and stability. All of the improvements included in the OSR2 release of Windows95 and the ISDN1.1 Accelerator Pack have been included in this package. This Dial-Up Networking 1.2 upgrade can be applied to existing Window95 systems, including the retail release and OEM Service Release 2 (OSR2). This package cannot be used to upgrade a Memphis Developer's Release or future Memphis beta releases. (Note that the features provided by this Dial-Up Networking Upgrade are already present in the Memphis Developer's Release.) Installation To install the upgrade, simply execute the MSDUN12.EXE file and follow the instructions. The installation process will require you to reboot the machine, and may ask for your Windows95 installation disk if you originally installed Windows95 from a CD. If you encounter a "do you want to keep a newer file" dialog, always keep the newer file. After the boot, you may see a DHCP error message asking if you wish to see future DHCP error messages. (Select "yes".) Beta users can install the Dial-Up Networking 1.2 upgrade over a previous beta version of the upgrade without removing the previous version. A Winsock 1.1 upgrade has also been provided as a single self-installing file. An upgrade to Winsock is necessary to correct DNS and WINS name resolution problems that were present in the original release of Windows95. If you are running an application like the MS Winsock Proxy Agent which modifies Winsock, you should uninstall the application before before updating Winsock, then re-install it when you are finished. Microsoft has also released a completely redesigned Winsock2 to developers and early adopters. Winsock2 is available from the Microsoft ftp site. It is fully compatible with the Dial-Up Networking 1.2 Upgrade. Further Information The installer places two documents in your system's windows directory. You should read the document titled Dial-Up Networking 1.2 Release Notes to better understand the network implications of both dial-up and PPTP connections. Several known bugs and/or limitations are also described in these release notes. Additional technical information on pptp and default routing is provided in the document titled About PPTP and Dial-Up Networking 1.2.
