The win 2k machine can communicate with all four win 98 machines. Two machines do not require passwords to access the win 2k or any of the other win 98. Two can communicate with all win 98 machines but require a password to talk to win 2k (no passwords had been set up previously since this is a home system).
Attempting to set up users with passwords on the win 2k does not fix the problem. One of the Win 98 (actually a laptop with win 95) is not even shown as a user but can communicate with win 2k. The network settings on all Win 98 machines appear to be the same.
How do I change the two win 98 machines to be able to talk with the win 2k?
