How to verify smb1 protocol is enabled on Microsoft AD 2012 for CPPM auth to work
Requirement:

How to verify Microsoft AD 2012 server has SMB1 protocol Enabled, if not how to enable it?

 



Solution:

We would need to run the below command on the powershell of the AD:

Get-WindowsFeature -Name FS-SMB1

To check if the SMB1 is enabled, we would see the output as below:

 

PS C:\Windows\system32> Get-WindowsFeature -Name FS-SMB1

Display Name                                            Name                       Install State
------------                                            ----                       -------------
[ ] SMB 1.0/CIFS File Sharing Support                   FS-SMB1                        Available


PS C:\Windows\system32>

 

In the above output, we could see the install state is Available, which means it is Available but not installed, the install state should be showing has "Installed" if its enabled.



Configuration:

We could run the below command to enable the SMB1 protocol on the AD 2012 and restart the AD.

Note: We would need to execute this action during the down time as we would need to restart the AD server for this command to take affect.

 

# Add-WindowsFeature -Name FS-SMB1

Following with the server restart the AD should now have SMB1 protocol enabled.



Verification

Post execution of the command and a restart, now we should see the SMB1 as installed as shown below:

 

PS C:\Windows\system32> Get-WindowsFeature -Name FS-SMB1

Display Name                                            Name                       Install State
------------                                            ----                       -------------
[ ] SMB 1.0/CIFS File Sharing Support                   FS-SMB1                        Installed


PS C:\Windows\system32>
