sharing a database on 2 pc's, one vista / one is xp

Hello all,

This is really a computer sharing / network question, so sorry for posting
here; it's the only newsgroup I post in.

I have a customer with a database file on a vista machine under Users\[user
name]\, who has a 2nd pc with window xp. They're getting all kinds of access
errors relating to the .mdb being read-only, etc., when they try to access
the database from the xp machine.

Using remote control, I turned on sharing for that folder with full rights
on the vista machine, then I connected to the xp machine. Still no luck. As
a test, I opened Notepad, and tried to save a quick .txt file to that
folder, and received "you do not have permission to save in this
directory.."

What's the secret to sharing a folder, with full rights, on vista? Does the
database have to reside in a certain folder? Or do you need to go into the
security tab and somehow add the 2nd user? (the security tab is a mess in
vista, btw)

Thanks!

Andy
