Instead of logging in as George Lawshe, log in as Administrator.
Another option would be to create another user account on each of the
Win 2000 machines with George Lawshe as the user name. Passwords are not
required. The Windows 2000 machine will not allow any other computer to
access shared files or anything if that remote computers login name and
password don't match a local account.

In other words here is what is happening now. Your Windows 98 machine is
sending a request to view files on the Windows 2000 machine. The Windows
2000 machine asks for a user name and password (behind the scenes in the
networking protocols). The Windows 98 machine responds with George
Lawshe - no password. Since the Windows 2000 machine does not have an
account named George Lawshe the request is rejected.

The key is to make sure that every machine has the same users and
passwords (or lack thereof) set up on them. Windows 2000 and newer
requires this to beef up the security on networks. Older Windows
versions had terrible security but it did make file sharing really easy.
Now that the Internet is connected with most networks, security is a
real concern.

Hope that helps.

Tim has hit the nail on the head - use a username (and password, if one is
used) that you use to log onto the Windows 2000 computers.
