SYMPTOM

DR DOS 6.0 and LANtastic 4.0 have been tested together by both Novell and
Artisoft, and were found to be compatible.

Customers with versions of either DR DOS prior to 6.0 or LANtastic prior
to 4.0 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.

SOLUTION

Testing of DR DOS 6.0 and LANtastic 4.0 revealed only a small number of
minor configuration issues:

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 it 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 from the Artisoft
forum on CompuServe.
