Vista File & Printer Sharing with W98 & WME

My VISTA desktop does not communicate well with my older Windows computers.

FILE SHARING: My desktops with W98 will share files to the VISTA desktop;
but only if the files are not password protected. When I attempt to logon to
the W98 files from the VISTA, I usually get a "Logon Unsuccessful" message.
This is sporadic, and I have been able to logon sometimes. I am able to "map
the network drive" and logon to the mapped drive with the VISTA using a user
name and password. This too is sporadic; however, and doesn't always work.

PRINTER SHARING: My WME laptop has the printer attached. The VISTA desktop
network displays the printer, runs the printer software, and says it is
printing. Unfortunately, the print goes to another planet in another galaxy,
never to be seen again.

VISTA SHARING: When I try to logon to the VISTA from WME or W98, the
Network Neighborhood shows the VISTA and its Shares. When I click a VISTA
share, the hourglass goes round and round for a long time. Eventually, the
Network Neighborhood browser shows VISTA folders with a single letter name
likd "D" that are not listed within the shared folder on the VISTA browser.
Clicking on the "D" returns a "You do not have permission" message. I have
set all the VISTA security and permissions settings to minimums; but have
never been able to logon to the VISTA box from W98 or WME boxes.

VISTA looks good and runs good. Just have problems with FILE AND PRINT
SHARING.
