Unable to connect to CIFS share from EMC Celerra with Windows 8 RTM

I just loaded Windows 8 Ent RTM and I am unable to browse any of our file shares from our Celerra NS-120. \\<name> returns "An extended error has occurred" dialogue box. Accessing any actual server shares using the same method works just fine. Network discovery is enabled.

Any ideas?

We're having the same issue. We cannot move forward with Win8 testing until a resolution is found...

This did fix my problem as well.   I ran into this during Windows 7 setup.  My question here would be, why did this start happening in Windows 7?  I can't figure out why this all of a sudden became an issue.  For me it started happening once we moved to deployment using ADK and MDT 2012, prior to that it didn't seem like a problem.  This could just be a coincidence, but I wish I had more of a hard reason why this became an issue.

gav46 posted the solution to my issue, but the commands required a couple minor changes.

1. Run PowerShell as Administrator

2. Set-SmbClientConfiguration -RequireSecuritySignature 1

Answer Y when prompted to confirm the modification.

3. Set-ItemProperty -Path "HKLM:\SYSTEM\CurrentControlSet\Services\LanmanWorkstation\Parameters" RequireSecureNegotiate -Value 0 -Force
