I have a NAS drive on my home network. Under XP I could map different drive
letters to different folders on the drive. Under Vista I was initially able
to set up the storage the same way, but now something has changed and I
cannot log on to the private folders, even though I provide the correct user
name and password.

This is not a NAS or Network problem as i still have the XP machine
available and can access the private folders with no problem.

Any thoughts?

It actually may be a NAS problem in that most NAS's use some form of
embedded Linux and will probably need updating to work with Vista since
authentication is different on Vista (see below). If you have the
ability to configure the Samba running on the NAS, you may make changes
there yourself although it is unlikely that you will have access to the
smb.conf file. You can try the fix for Vista below, but probably the
best solution is to contact the NAS mftr.'s tech support to see what
they say.

From Michael Bishop (MS) - Basically, the issue with Samba and Vista is
that Vista no longer permits LM or NTLM authentication by default; only
NTLMv2. Samba versions 1.x and 2.x only support LM and NTLM, so there's
an issue there.

Recommended solution: upgrade to Samba 3.x and enable NTLMv2 by adding
"client ntlmv2 auth = yes" to your smb.conf file. Because of another
issues with previous versions, I strongly recommend upgrading to 3.0.22
or later regardless of your choice for this particular instance.

Alternate solution: change Vista's security settings to permit
lower-security authentications. (as below)

To enable Windows Vista to connect to Mac OS X with Windows File Sharing
enabled, you will need to change the following policy in Windows Vista:

StartRunsecpol.msc [enter]

Click on "Local Policies" -- "Security Options"

Navigate to the policy "Network Security: LAN Manager authentication
level" and double-click it to get its Properties. By default Windows
Vista sets the policy to "NTVLM2 responses only". Use the drop-down
arrow to change this to "LM and NTLM – use NTLMV2 session security if
negotiated".

In Vista Home Premium, you won't have this tool so per Steve Winograd, do:

1. Run the registry editor and open this key:

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Contro l\Lsa

1. If it doesn't already exist, create a DWORD value named
LmCompatibilityLevel

3. Set the value to 1

4. Reboot

Thanks for the hint. I went to the Seagate website (since this is a Maxstor
NAS which is now part of Seagate) and they said the same thing. I did the
registry edit this AM before leaving for work. Now I have a different error
message that says "Multiple connections to a server or shared resource by the
same user, using more than one user name, are not allowed."

I was not able to try disconnecting the public drive on the share but does
this mean that I can only map ONCE to the share?

I wouldn't think so. I've got a Maxtor NAS at a client's - lots of XP
machines, no Vista ones - with many shares but I don't map any drives.
Check with the Maxtor's tech support. Or maybe someone else reading this
newsgroup knows.
