Workgroup - 98 & 2000

Enable the guest account on the Windows 2000 machine. To enable the guest
account on a Windows 2000 Professional machine go to:

Start/Settings/control panel/Administrative tools/ Computer Management
expand System Tools, expand Local Users and Groups Select Users folder. In
the right pain, right mouse click on the Guest account, go to Properties,
Uncheck the box that says "Account is Disabled" The red X on the guest
account should then go away. All users on the local network will have
access to all shared resources.

This step removes any security restrictions to log on to this computer. If
you have Microsoft Windows 98 network computers and they are trying to
connect to this computer, this is convenient mechanism to allow them to
connect and use shared resources. Each Windows 95 or Windows 98 computer
must also have File and Printer Sharing enabled and create shares for the
Windows
2000 computers to have access to resources on these computers. No passwords
should be set, unless you desire to set security restrictions.

Hope this helps!

Also,
have you checked the netbios-name of the win200 machine?

Make sure the name is conform with required form for .
If the name of the w2000 machine contains free spaces or is too long, win98 or
win95 won't be abel to see it. Same with printers.
That's at least what i experienced.

I tried that and it didn't work. They are in the same VLAN but no logged onto the domain. They are just working in a workgroup environment. The problem occurred after a technician for his home cable modem "fixed" his problem at home. Since then he has "fixed" it so he can't see the shared printer
