XP Pro cannot access Vista shared folder

I am trying to use a drive on my Vista Ultimate desktop machine for backup
purposes. I want to back up files from an XP Pro SP2 laptop. I have
followed all the instuctions in
http://www.microsoft.com/technet/net.../vista_fp.mspx. Both
machines use Windows Update to be up to date for Windows.

From the XP machine, using Map Network Drive/Browse..., I can see the name
of the Vista machine (in My Network Places/Entire Network/Microsoft Windows
Network/Workgroup), and a plus sign appears to the left of its name.
Clicking on the machine name shows no sharable folders, not even public
folders; the + simply goes away after a short time.

If I type the full pathname (without using Browse), after a long pause, I
get the message from Windows "The network path \\machine\folder could not be
found" (but with the actual machine and network shared folder names).

Examining the control panel on the Vista machine, it says network discovery,
file sharing, public folder sharing and password protected sharing are all
enabled. The workgroup, username, and password are the same for both
machines. I set up sharing for a few specific folders, and explicitly
allowed total access for the username. From the Vista machine's control
panel, if I click "Show me all the shared network folders on this computer",
I see the folders I set up for sharing.

As a last resort I turned off the firewall on both machines.... as expected,
this did not help.

Any help would be appreciated.

When the firewall was On, what was the Network Location Type? Start with the
firewall On, and NLT = Private.

If you enable PPS, you can use a non-Guest account ("the username"), but the
username has to be Activated for network use.

Chuck, thanks for your tips. I will check them out and report on the results.

Meanwhile, some more clues. I have another Vista machine which IS able to
connect to the aforementioned Vista shared drive... while the XP Pro machine
still cannot.

I remember a setting somewhere that has three options, the one in the middle
is a "less secure" option for systems without some kind of remote
authentication algorithm, whose name I forgot, but is only in Vista. I have
chosen that "less secure" middle option.

You're _probably_ discussing NTLM Authentication. This is a relevant setting
with a Windows 9x computer on the network, less relevant (not necessarily
irrelevant) with Windows NT / 2000 / XP.

You also could check SMB Encryption and Signing.

I'd still look at the NLT though, to start. And the NetBT setting.

Have you found a solution to this as of yet? If not (or for anyone else experiencing this problem), try this: START > NETWORK. You may have a yellow bar just below the menu bar that says "File sharing is turned off ... Click to change". If so, clicking this should solve the problem.

If you are planning to enable the Vista Guest account, and allow XP and Vista PCs to access a Vista shared folder without being forced to create same-name user accounts on the Vista PC, then you will need to disable Password Protected Sharing.

1) Right click on your Network icon
2) Click on Password Protected Sharing
3) Turn it off

For this to work, you must have enabled your Vista guest account... and your Vista shared folder(s) must have Security settings to allow "Everyone" to have either Read and Execute | or Full Control.

Thank you for the tip. FYI, for security reason, we don't recommend to
enable guest account.
