With fresh installation of Windows 2012 and Windows 8, you can’t access old SMB share or CIFS share correct.
The solution is following.
· To enable SMBv1 on the SMB client, run the following commands:
sc.exe config lanmanworkstation depend= bowser/mrxsmb10/mrxsmb20/nsi
sc.exe config mrxsmb10 start= auto
· To enable SMBv2 and SMBv3 on the SMB client, run the following commands:
sc.exe config lanmanworkstation depend= bowser/mrxsmb10/mrxsmb20/nsi
sc.exe config mrxsmb20 start= auto
Run following Powershell command to disable new security negotiate on SMB 3 which some third party doesn’t support.
Be aware once you disable this security negotiate, you need to disable all Windows 8 and Windows 2012 in your environment so they can talk to each other.
Set-SmbClientConfiguration -RequireSecuritySignature $false
Or
Set-ItemProperty -Path “HKLM:\SYSTEM\CurrentControlSet\Services\LanmanWorkstation\Parameters” RequireSecureNegotiate -Value 0 -Force
Powershell command to enable win8/2012 to access EMC VNX cifs server:
Set-SmbClientConfiguration -RequireSecuritySignature $true
Set-ItemProperty -Path "HKLM:\SYSTEM\CurrentControlSet\Services\LanmanWorkstation\Parameters" RequireSecureNegotiate -Value 0 -Force
