W2K Pro & XP Pro boxes can't access shared drive C on Win 7 Pro 64bit

On this wired homebiz LAN (Netgear router), boxes A through F belong to one workgroup. A runs Ubuntu, B runs W2KPro with IIS 5, C and D run XP Pro with Apache server 2.2, E runs XP Home with no web server, and new box F runs Win 7 Pro with IIS 7.5.

-- all can ping one another

-- all can run web apps on A, B, C, D and F

-- B, C, D and E can access hard shared hard drives on one other

-- F can access shared drives on B, C, D and E.

-- But the W2K & XP boxes (B,C,D,E) cannot access the shared drive C on the Win 7 Pro box (F).

All those boxes report drive C in F is "not accessible".

Under "Ädvanced sharing " in F under Win 7 Pro, that drive is marked Shared, given a Share name, and given appropriate permissions.

And in the network and sharing center in Win 7 Pro,
-- Network discovery is on,
-- File & printer sharing is on,
-- Public folder sharing is on,
-- Media streaming is on,
-- File sharing using 40|56 bit encryption is permitted,
-- Password protection is off,
-- Allow Windows to manage homegroup connecitons is on.

I also tried ...

-- flipping public file sharing
-- the EnableLinkedConnections fix Programs may be unable to access some network locations after you turn on User Account Control in Windows Vista or in Windows 7

Neither made the slightest difference.

Those are all the suggestions I've found on the web.

It's a dealbreaker. If we can't access that drive from the LAN, Win 7 has to go.

If anyone has succeeded in accessing a shared drive C in Win 7 Pro from XP Pro or W2K Pro boxes on a LAN, please would you describe how you did it?

Have you tried making adjustments on the Security tab of the Windows 7 drive that you can't access?

If you go to the Security tab on the problem drive try using the "Edit" button and putting check marks for full permissions to access the drive for everyone.

Thank you for the suggestion. The solution was to add user "Everyone" to that list, and grant "Everyone" all privs. Thank you, problem solved.

Yes sometimes the security tabs needs to have full permissions for everyone depending on the machines you need to access the drive with.

I'm glad that worked for you.
