Q:
Unable to access EMC Celerra file system from Vista
Windows Vista, Windows XP, EMC Celerra
I have file systems exported from EMC Celerra to Windows XP and vista machines. I can access these fine from XP clients, but not from Vista clients. Any settings either on Vista or Celerra that I should be worried about?

NO Clariion is a SAN array. Celerra is a NAS. The problem is Vista insists on a higher level of security that MS added after the version of CIFS the Celerra is using. To fix:

Under “Local Policies” and “Security Options” open the “Network Security: LAN Manager authentication level Properties” entry. Change the value to “Send LM and NTLM – Use NTLM-v2 session security if negotiated”.

Additionally...

Any recent version of Celerra code will also support Kerberos based authentication if you want to restrict it or your clients to that.

You probably also want to enable SMB2 on the Celerra since your Vista and I think XP SP3 clients will try to use that if they can. It may be that your Vista clients have been configured to require SMB2.

You can enable SMB2 on the Celerra with the following Control Station CLI command:

$ server_cifs server_x -add security=NT,dialect=SMB2

Other answer
A Celerra is a SAN so the files should be shared through a server. If the vista machine is not able to see the file shares, you should check permissions and see if the machine is on the same domain.

That was awesome. I havent tried the solution yet. But, I assume you know it works. I mean who would ever think of digging in that deep to that particular parameter.

Am I glad I asked this question on here. Awesome!! Thanks!

It wasnt the NTLM part that resolved it.
I had to enable SMB2 on the data movers, and that allowed Vista machines to communicate properly.

Thanks!
