          TITLE:  DR DOS 6.0 COMPATIBILITY WITH LANTASTIC NETWORK
   DOCUMENT ID#:  FYI-M-1406
           DATE:  06NOV92
        PRODUCT:  LANtastic & DR DOS
PRODUCT VERSION:  4 & 6.0
     SUPERSEDES:  13DEC91

ISSUE/PROBLEM

DR DOS 6.0 and LANtastic 4.0 have been tested together by both
Novell and Artisoft, and were found to be extensively compatible. 
Customers with earlier versions of either DR DOS or LANtastic may
achieve partial functionality when running the two products
together.  However, such functionality is coincidental and is not
supported by either Novell or Artisoft.  Customers who have earlier
products and who experience problems should upgrade LANtastic or DR
DOS as necessary.

Testing of DR DOS 6.0 and LANtastic 4.0 revealed only a small
number of minorconfiguration issues, which are as follows:

1.   SUPER PC-Kwik 
     Super PC-Kwik advanced disk reads and writes should be
     disabled on LANtastic because the Super PC-Kwik scheduler
     conflicts with the LANtastic scheduler causing machines to
     hang.  To avoid this problem on a machine running SERVER, use
     the Super PC-Kwik switches /D- /H- to disable advanced disk
     reads and writes.  Normal caching is still active when these
     switches are used.

     Note that you do not need to disable advanced disk writes on
     a node which is not running SERVER.

     As is true of most server/cache combinations, Super PC-Kwik
     cannot cache redirected network drives. 

2.   WINDOWS 3.0 IN ENHANCED MODE 
     To run Windows 3.0 in enhanced mode using the DR DOS 6.0
     EMM386.SYS memory manager, customers need to use an Artisoft
     LANTASTI.386 driver dated 08-16-91 or newer.  Customers with
     older LANTASTI.386 files can obtain a current driver from
     Artisoft Technical Support.


3.   LANPUP UTILITY
     Network redirections work properly under DR DOS 6.0, however,
     the LANPUP terminate and stay resident utility will not
     display the redirection properly.

4.   DR DOS 6.0 DISK UTILITIES
     Certain DR DOS 6.0 disk utilities are intentionally designed
     for use only on local drives and will return an error message
     if run on a redirected (network) drive or on a machine running
     the SERVER program.  These utilities are summarized below:



     Utility            On SERVER?     On network drive?
     -------            ----------     -----------------



     CHKDSK                  N               N

     DELPURGE                N               N

     DELWATCH                N               N

     DISKMAP                 Y               N

     DISKOPT                 N               N

     FDISK                   N               N

     FORMAT                  Y               N

     PASSWORD                Y*              N

     RECOVER                 N               N

     UNDELETE                Y               N

     UNFORMAT                N               N

     * Files on a server protected by PASSWORD cannot be accessed
     from LAN workstations, even when the correct password is
     provided.  They may, however, be accessed at the server on its
     own physical drive.

5.   SUPERSTOR
     One LANtastic 4.0 test system was run with a DR DOS 6.0 server
     whose hard drive had been prepared using the SuperSTOR disk
     compression utility.  All nodes on the network, even non-DR
     DOS nodes, could access data on the SuperSTOR drive.   Efforts
     were made to exercise the test system heavily, however
     customers should consider use of SuperSTOR partitions on
     LANtastic servers as "at their own risk" at the current time
     and use standard precautions such as frequent backups of
     essential data.   We also strongly recommend that customers
     read DR DOS Technical Tip # 1200 before creating or using a
     SuperSTOR drive.

6.   RARE QUICKBASIC PROBLEM 
     The initial shipments of DR DOS 6.0 had a rare problem in
     which server pathing was not handled correctly by a Microsoft
     Quickbasic application under LANtastic 4.0.  This problem was
     reported by only a single user in the field and was very
     difficult to reproduce even in our testing laboratories so is
     unlikely to be seen by most customers.  The problem relates to
     the "double backslash" \\ before the server name, and has been
     corrected.  Customers who see the problem, and who have DR DOS
     files dated prior to 12/91, should contact Novell technical
     support for updated files.

7.   TASKMAX
     LANtastic software should be loaded before TASKMAX is invoked. 
     This permits all TASKMAX task sessions to access the network. 

8.   INTERNATIONALIZATION ISSUES 
     (Country, Keyboard, Codepage, and Graftabl) The U.S. version
     of LANtastic will run only with the default (U.S.) DR DOS 6.0
     country and keyboard.  DR DOS 6.0 customers who require
     alternate country support, codepage, or graftabl support
     should contact Artisoft for an international version of
     LANtastic 4.0.

9.   NET PRINT, NET EXPAND, & NET DIR
     These commands will fail on DR DOS 6.0.  Call the Lantastic
     BBS (602-293-0065) for the patch called DRXCIP.EXE, a self
     extracting archive file. 

ADDITIONAL INFORMATION
Artisoft provides a similar but more extensive document on DR DOS
6.0 compatibility with LANtastic 4.0.  This document, which details
the hardware and network cards tested, can be obtained from
Artisoft's technical support bulletin board at (602) 293-0065 or
