*********************** GATEUNST.TXT **********************

NOTE:  The enclosed GATEUNST.BAT batch file is intended for
       use in either a LANtastic for DOS/Windows 3.1x or a 
       LANtastic for Windows 95 environment. On a Windows 
       95 machine it is intended to be run either from a 
       DOS window on a system which has either of the 
       Server or Client components of the LANtastic 
       Internet Gateway installed, or by launching the 
       batch file from the 'Start/Run' tabs on the 
       Windows 95 desktop.

       On a Windows 3.1x machine, it is intended to be run 
       from DOS (not a DOS window.) 

       This batch file will remove the LANtastic Internet 
       Gateway components from the machine on which it is 
       run. It will also attempt to restore a Winsock that
       had been previously installed prior to installing 
       the Gateway. Be aware that as the Gateway does not 
       support Win32S in a Windows 3.1x environment, the 
       GATEUNST.BAT program will not attempt to restore any
       WSOCK32 files in the Windows System directory. It 
       will be necessary to reinstall Win32S to reenable 
       32-bit Winsock support after running this program. 

***********************************************************

Overview:

This program works by removing the LANtastic programs and 
changing the key pointers in Windows 95 to reflect the 
changes. Upon rebooting the computer, the gateway code 
will no longer be present on the machine and references to
the programs will be removed from the Control Panel and 
Startup folder. The LANtastic menu program will still show
an option to Assign Internet Connections, but the button 
will no longer function. If Gateway functionality is later
desired it will be necessary to rerun the LANtastic 7.0 
Setup program either from CD-ROM, diskettes, or Install 
resource.

In a Windows 3.1x environment, this program works by 
deleting the Gateway files from the Windows directory. It 
will attempt to reenable a previously installed 16-bit 
Winsock by renaming WINSOCK.001 to WINSOCK.DLL. 

Issues:
This procedure is very straightforward on a Gateway server. 
This machine is already using the WINSOCK.DLL and 
WSOCK32.DLL files that are provided by Windows 95 so there
is no need to replace them. It is only necessary for the 
batch file to update the pointers and remove the gateway 
programs. 

Other issues need to be considered on a Windows 95 client 
machine. This batch file expects the original WINSOCK.DLL
to be present in the Windows directory with the name 
WINSOCK.000. The original WINSOCK.DLL program is saved 
with this name during the Winsock Gateway installation. 
The Windows\System file, WSOCK32.DLL, is likewise renamed 
to WSOCK32.000. If these files are not present with the 
.000 extensions when the GATEUNST batch file is run, users 
will be warned that the original files need to be present 
before Winsock operations can be performed. 

A Windows 3.1x machine may not have a previous version of 
WINSOCK.DLL available as one is not provided with Windows 
3.1x by default. The original Gateway installation 
program searched for WINSOCK.DLL in the Windows directory 
and if one was found, renamed it to WINSOCK.001. 
GATEUNST.BAT will try to rename WINSOCK.001 back to 
WINSOCK.DLL. If this fails, the user is presented with the
warning that one must be provided for Winsock applications 
to work.

The original Windows 95 distribution versions of these 
programs are: 

WINSOCK.DLL      42080 bytes dated 7/11/95 at 9:50am
WSOCK32.DLL      66560 bytes dated 7/11/95 at 9:50am

Depending upon the user's individual configuration, a 
different WINSOCK and WSOCK32 may be necessary. Due to 
the huge number of possible permutations, this program 
does not check for this possibility and only reactivates
the original Windows 95 Winsock files that were disabled 
when the gateway was installed. If a non-default 
Windows 95 Winsock is desired; it will be necessary to 
either install the non-default Winsock from the 
application or put the files in place manually. Artisoft
assumes no responsibility for installing and configuring
third-party Winsock applications.


To Use:

*** IMPORTANT NOTE ***
It is imperative when running from a DOS window that the 
window's Properties be configured for 'Suggest DOS mode 
as necessary.'  If this is not performed, the update will 
not take place and the gateway will not be properly 
deactivated. To check this potentiality, right-click on 
the MS-DOS prompt icon. Select 'Properties.' Click on the 
'Program' Tab. Click on the 'Advanced' button. Ensure 
that there is a check-mark in the 'Suggest DOS as 
necessary' field. There should be no other check-marks in
the other fields. Disregard this note if running the 
program from the Start/Run option on the Desktop.

1. Copy the GATEUNST.BAT file to the Windows directory of 
a machine running either the Gateway Server or Client 
programs.

2. Either open a DOS window from Windows 95, type 
GATEUNST <Enter> and follow any prompts. 

Or, from the Desktop, Select 'Start,' 'Run,' enter 
GATEUNST, and follow any prompts.

3. After the system has made its changes and rebooted 
itself, the GATEUNST.BAT program may be removed.
