ABSTRACT:

This document contains instructions for setting up a workgroup
with PERSONAL NetWare 1.0 and resolving workgroup related
problems that could occur due to hardware or software
configurations.

ISSUE

For convenience and security the network can be divided into
workgroups, each containing one or more PERSONAL NetWare servers.
A workgroup consists of a number of users who require the same
access to certain information.  Rather than making a file or
directory available to any user on the network, you can make it
available to the members of a workgroup only.


PNW WORKGROUP FACTS:

1.  A server and its resources can only belong to one workgroup
at a time.

2.  A user can only be logged into one workgroup at a time.

3.  Users are only able to see resources belonging to the
workgroup to which they are currently logged into.

4.  If Novell NetWare is part of the network and multiple network
addresses (segments or routes) exist, workgroups are not limited
to a single segment but can span multiple network addresses
(segments or routes).

5.  If a user's machine belongs to workgroup A, it is possible
for the user to log into workgroup B and use the resources
available in workgroup B without moving the server and server
resources to workgroup B.

6.  To move a server from one workgroup to another, you must know
a valid username/password combination for the new workgroup.

7.  It is possible to have two workgroups with the same name on a
network.  If this happens, users will be confused because the
assumption from users is that there is only one workgroup when in
reality there are two or more separate workgroups with the same
name.  This situation is rare, but is easy to confirm and
correct.

8.  A workgroup exists as long as there is at least one server
that belongs to that workgroup.  After there are no servers in a
given workgroup, the workgroup will be automatically deleted. 
Stated in another way, the only way to delete a workgroup is to
move all of its current servers to a different workgroup or
workgroups.

9.  For small networks, one workgroup is probably sufficient.
     

CREATING WORKGROUPS

The initial creation of a workgroup is accomplished by running
SETUP/FIRST after the installation of PERSONAL NetWare 1.0.  If
more information is desired about creating workgroups, please
refer to chapter 4 in the PERSONAL NetWare manual.  Pages 4-3
through 4-6 discuss the specific steps required to create a
workgroup.  If a new workgroup is created, the machine where the
new workgroup was created will become the first server in the new
workgroup.  A workgroup must have a server in it before it can
exist.  Remember, SERVER.EXE must be loaded before a workgroup
can be created.


DUPLICATE WORKGROUPS

One of the more common problems that can occur when installing
PERSONAL NetWare 1.0 is the inadvertent creation of duplicate
workgroups.  If PERSONAL NetWare 1.0 is installed onto two
machines that cannot see each other on the network because of
interrupt conflicts, corrupt files, or different frame types,
then it is possible to create a workgroup on a network server
that might have the same name as another network server
workgroup.

This condition can also occur if a workgroup is created during
the PERSONAL NetWare installation on one machine and then that
machine is turned off while a workgroup with the same name is
created during the installation of PERSONAL NetWare on a second
machine.  This situation cannot occur if the machines can
communicate on the network and both machines are turned on as
PERSONAL NetWare does not allow a workgroup to be created if that
workgroup already exists on the network.  This prevents duplicate
workgroups from being inadvertently created.

If two machines have had a communication problem and now have
workgroups created on them that have the same name, and later a
hardware or configuration problem was solved so that the machines
can now see each other, then the following error message will
occur when logging in to one of the workgroups or when a NET
WGLIST is issued:

MESSAGE
     
     Duplicate workgroups were found!
     Available Workgroups
     ---------------------------------
     ---------------------------------
     1.  WGNAME     020f42CB
     2.  WGNAME     7F6723E7

     Type the number corresponding to the
     workgroup to select or type M to get
     the extended workgroup list (Enter to exit):

The solution to this problem is really quite simple.  One of the
workgroups needs to be deleted and the server(s) in that
workgroup needs to be moved into the other workgroup.  There is
no way to delete a workgroup other than to move all servers out
of that workgroup, and then the workgroup will cease to exist.  A
subsequent NET WGLIST will not display the workgroup that the
server(s) was moved from.

It can be confusing to know which workgroup belongs to that
machine.  The easiest way to resolve this problem is to create a
new workgroup with a totally different name, and then move one of
the servers to the new workgroup.  At this point, there would be
two workgroups but the workgroups would have different names and
would be easily associated with a particular machine by typing
NET INFO.

To remove or delete a workgroup, perform the following from the
machine whose workgroup is to be deleted:

1.  Type NET ADMIN
     
2.  Highlight the server that is to be moved (the one that shows
LOCAL, IN WORKGROUP WGNAME in the NOTES column).
     
3.  From the pull-down menu, pull down WORKGROUP and press ENTER
on CREATE.
     
4.  Enter a workgroup name that is distinct from the other
workgroup names and press ENTER on OK.

5.  A note will be displayed that says THE SERVER ON THIS MACHINE
IS NOW IN WORKGROUP [WGNAME].  Press ENTER on OK.

6.  Highlight the local server again and press ENTER.

7.  Highlight SET WORKGROUP and press ENTER.

8.Highlight the workgroup to which the other machine belongs and
press ENTER.  (There should only be one at this point.  If not,
then there are other servers that are still in the workgroup that
you are trying to delete.)

9.  Highlight OK and press ENTER.

10.  The user can then login to that workgroup by entering his
username and password and pressing ENTER on OK.

11.  A message will appear that says that the server is now in
workgroup [wgname].  Press ENTER on OK.

12.  The machines are now in the same workgroup.  If the user
issues NET SLIST, at least two machines will be in the same
workgroup.


MACHINES DON'T COMMUNICATE

It is also possible that two machines are functioning perfectly
but they do not see each other on the network.  One of the
possible causes of this condition is that the user has set up
each machine so that it is in its own workgroup.  If the user
enters NET SLIST, he can only see his own server.  If the user
enters NET WGLIST and sees more than one workgroup when only one
workgroup is desired, then he needs to move one of the machines
so that they are all in the same workgroup.

The solution is similar to the duplicate workgroup solution where
one of the server machines needs to move his server into the
other workgroup.  After the move, then the previous workgroup
will cease to exist assuming there are no more servers in that
workgroup.
