fixed it myself! thanks for the encouragement.
Turned out the log on accounts of those student machines on my PDC
allowed them to only log on to that specific machine they would work on
in the lab.
I added the 98 machine's name to that list of allowed machines they can
log on to, and it works!
I am now BETTER off than I was with winxp pro (since it only allowed 10
users in a share folder). I tested it and all 25 computers can get into
the share folder no problem! You must have bad information. Windows 98
has a default of 100... maybe that question wasnt on the test-king
sheet.
Too bad your paper-certs are good for nothing but pretty wall
decoration in your room.
