LAN winth win2K

How does one configure Win2K for a home LAN?

I am setting up a LAN with three computers. Two with win98 and one with Win2k.

1. Chose the “share-level access control”
option and am promted to type in a user
name & p/w any time I access the Win2K
workstation from one of the other two
workstations.
Unfortunately any password I enter is said
to be invalid. Pls. Help

Thanks

Ben.
