Hi!

I have 4 windows XP computers (Home/Pro) where user names and
passwords don't match.
One of the computers has a few shares that I want to make
accessible to everyone but don't require them to enter
username/password every time.

What do I need to Enable/Disable in local security policy on the
computer with shares so clients can access shares anonymously

I assume that the computer that is sharing the files is an XP Pro
machine. Try enabling "Simple File Sharing". This should force all
clients to connect using the "Guest" account and not need
authentication.

To enable "Simple File Sharing":
Double-click any folder, then
Tools-Folder Options-View
I believe the last checkbox is the list is for "Simple File Sharing".
Check that box.

To make sure that the Guest account is active:
Start - Run - Cmd
In the window that opens up, enter the command:
net user guest /active:yes
Also make sure the Guest user does not have a password.

HTH,
John
