The last time I fixed this problem I simply uninstalled the
client on the General page of the network connection
properties. It now looks as if the latest version can be
removed by using the Add/Remove applet in Control Panel.
Quoting from the article:
--
Windows 2000/XP (Novell Client versions prior to 4.9): From the
Control Panel open the "Network and Dial-Up Connections"
applet. Highlight any "Local Area Connection" or "Dial-Up
Connection" entry where the Novell Client for NT/2000 is being
used, and use File | Properties to bring up the properties
dialog for that connection. Highlight the "Novell Client for
Windows 2000" entry in the connection properties and then press
the "Uninstall" button. Windows will confirm that you want to
remove the Novell Client for NT/2000 from all connections and
not just the current connection. Confirm "Yes" to this prompt
and the Novell Client for NT/2000/XP and dependent Windows
network services will be removed.
The Novell Client for Windows NT/2000/XP version 4.9 allows the
client to be removed from the Control Panel, Add/Remove
Programs interface. It is listed as "Novell Client for
Windows." This procedure accomplishes the same thing as the
procedure described in the preceeding paragraph.

After you remove the client you'll need to go to Control
Panel -> User Accounts and click on "Change the way users log
on or off" in order to restore Fast User Switching.
Good luck
