I am running netware 4.2 using the netware client32. and a 2000server. I created a logon.bat using notepad under scripts located in c:\winnt\sysvol\sysvol\domain\script\logon.bat.
the bat file maps the drives an example map line is
net use g:\server2000\sys
under active directory users and computer go to the user under userprofile, logon script and type logon.bat
on client 98/95
tcp properties choose static or dynamic, under client for ms windows add domain and under the identifiaction tab at workgroup add the domain name. if you can't login still after this on client uncheck any tcp binding under ipx/spx and try again. Hope i remebered everything and hope this helps.
logging in from 2000pro is more complicated try 95/98 machines first.
