Unable to map drive in Vista - Solution finally found

This mapping issue in Vista via Easy Search 3.50 is an issue with the version of samba used on the DNS-323:

Run secpol.msc

Go to: Local Policies > Security Options

Find "Network Security: LAN Manager authentication level"

Change Setting from "Send NTLMv2 response only"
to
"Send LM & NTLM - use NTLMv2 session security if negotiated"

Vista defaults to only send the more secure NTLMv2 protocol, which these NAS devices / Samba do not support.


Hope this helps someone out here.

Re: Unable to map drive in Vista - Solution finally found

Some flavors of Vista don't have secpol.msc, so if you using Vista Home.  You'll need to modify the registry directly to make it work.  The following key needs to change.

HKEY_LOCAL_MACHINE\System\CurrentControlSet\Control\Lsa\LMCompatibilityLevel

Its default value is 3, which is for NTLMv2 only.  Change it to 1 for "Send LM&NTLM - use NTLMv2
session security if negotiated"

Or  you can try the following.

Changing the security settings.
1. Click "Start" -> "All Programs" -> "Accessories" -> "Run".
2. Type "secpol.msc" and click "OK".
3. Allow Windows to open the Security Policies window by clicking "Continue".
4. Click "Local Policies" and choose "Security options".
5. Right click on "Network security: LAN Manager authentication level" and select
"Properties".
6. Change the value "Sent NTLMv2 response only" to "Send LM&NTLM - use NTLMv2
session security if negotiated".
7. Click "Apply" and "OK" and close the Security Policies screen.
8. Reboot your computer.
You can now map a network drive to your computer with the steps below:
1. Right click on "Computer" and select "Map network drive...".
2. Select the drive letter you want to use (for example "Z:").
3. Type the folder which you want to map (for example "\\DNS-323\Volume_1").
4. Click "Different user name" and type the username "Guest" (or another username)
and the password which is configured for the DNS-323 share.
5. Click "OK" and Click "Finish".
Your DNS-323share is now mapped to a driveletter on your computer.

Re: Unable to map drive in Vista - Solution finally found

The tip for modifying the registry in Vista solved the login problem.  However, if I have three drives mapped (all with auto connect), I only get one drive connected during a cold/warm boot. The two drive mappings work if I manually login.  Is this a work around to this problem?

I had the same issue, so I just mad a bat file that starts up automatically with windows (just put it in the startup folder)
put:

net use y: \\192.168.0.32\volume_1/persistent:yes /user:"user"  "pass"   (fill in user and password without "")

goodluck

You shouldn't need to run that as an automatic batch file - entering it once from a CLI should be sufficient - that's what the "persistent:yes" option is supposed to do.

I have been running this as a startup batch as well, both of my XP systems on reboot will not connect to the DNS-323 without re-entering the credentials. Even with the /persistent.
