Connecting to a Network Attached Storage device

I have a Buffalo Terastation on my network. My older XP computer, all the
Macs and Linux machines connect to it using standard Windows networking
protocols (SMB). In Vista RTM, the device shows up in the network display
and the shares on it also appear. However if I try to connect to a share to
read or write, I am prompted with a login box that wants to either use the
form username@domain (no domain here - workgroup only) or \domain\username.
In XP I would simply enter the username on the NAS and the password, no
autocompletion or inclusion of domain/workgroup name would happen and the
connection would be immediate.

The Vista RTM machine is configured to be part of the same workgroup as
every other computer on the network. Topology is all computers and devices
connect to a gigabit hub/switch, no VLANs or other complexities.

The computer I am using for Vista RTM is a Thinkpad T43P in a dock. I know
it connects because I have multiple drives for it. Native XP, SUSE Linux
drives when installed connect properly so I know the issue is not hardware.

I would appreciate some guidance in how to connect to the network share so I
can try moving some files onto the Vista machine to complete some testing.

Cheers
 
Hello,

Please try this:

- Click Start
- Click Control Panel
- Click System and Maintenance
- Click Administrative Tools
- Double-Click Local Security Policy
- In the left pane, click the triangle next to Local Policy
- In the left pane, click Security Options
- In the right pane near the bottom, double-click "Network security: LAN
manager authentication level"
- Click the drop-down box, and click "Send LM & NTLM - use NTLMv2 session
security if negotiated"
- Click OK
 
Thank you very much Jimmy. I have not had time to go through the security
docs for Vista and as you may have gathered am not an AD guy. I would not
have found this and that would have reduced my assessment of Vista. Great
work and thanks again.

I am having this same problem. When I follow your instructions the drop down
list is not active. Is there another setting I have to activate to enable
this?
 
I'm having the same issue and have tried the fix below with no success. I
have double checked all settings on the Storage Drive, as well as my domain
credentials. I am able to access it with no issues on my XP machine but when
attempting to access with the Vista machine just get a User name and password
login box, have tried all combinations of login/passwords with no luck, it
does not even seem to be trrying to authenticate because there are no
security violations showing up. Any other ideas?
 
When the login box appears enter your workgroup name and username in the
username box in this format 'WORKGRROUP\username' and the password as
normal.

Obviously enter your real workgroup and password name in place of the
examples but keep the Workgroup name in capitals.

Why Vista requires this when XP/Linux don't I have no idea but I need to do
this to acces my NAS and it's a PITA. Also I've found that even if you map a
drive and choose to use different credentials (in order to add the workgroup
name) whenever I want to access files on the mapped drive it often prompts
me to re-enter the credential (the first time only) even though I chose to
remember them.

Strange (and a pain) but it works for me.
 
Ian,

Thanks for the response, but that does not seem to be working either. I
have tried all plausible configurations of the **\** my PC name the domain
name, administrator rights etc. I am curreclty connected to a domain and I
can access all my servers without issue it only appears to be this NAS that I
cannot access. I have talked with networking support and they also did not
have any clues to this, they are going to try to upgrade the firmware on the
drive iteself but all security settings seem to be set to the correct
levels/security for this to work. There is NO user name and password set on
the drive, we tried to set one up and test but that also did not work. This
functionality works perfectly fine with XP

Thanks
 
I am having the same problem. I have followed the steps you said, but I have
a problem.

When I click Start, Control Panel, System and Maintenance, Administrative
Tools, this is as far as I can go. I am not able to find the Local Security
Policy. Here is what I have.

Computer Management
Data Sources
Event Viewer
iSCSI Initiator
Memory Diagnostics Tool
Reliability and Performance Monitor
Services
System Configuration
Task Scheduler
Windows Firewall with Advanced Security

Please advise how to continue since the Local Security Policy isn't showing
up.

Thanks.
 
The better solution is to upgrade your NAS device -- this happens on
Samba-based NAS boxes running a version of Samba earlier than 3.0.22.
First, contact the manufacturer for an update to a later version of Samba.

If they don't have an update available, then the above post is a good
workaround. Since you don't have secpol.msc (Home versions don't), run
regedit.exe and go to
HKEY_LOCAL_MACHINE\System\CurrentControlSet\Control\Lsa\LMCompatibilityLevel.
By default, this is 0x3; change it to 0x1.
 
I was trying to use this solution, but my local security policy Network
Security: Lan Manager Authentication is grayed out. I tried using the local
administrator account and my domain administrator account. I am doing R&D on
Vista Enterprise for our company. Any ideas?
