Enabling vCenter Server Appliance (VCSA) to use SMB2

VMware’s KB (https://kb.vmware.com/selfservice/microsites/search.do?language=en_US&cmd=displayKC&externalId=2134063) about joining the appliance to the domain only shows the option of enabling SMB1 on your domain controller. ¬†With VMware Support, we were able to figure how to enable SMB2 communication from the vCSA to the domain controllers.

  1. SSH into the vCSA
  2. enable the bash shell
    1. shell.set --enabled true
  3. enter the bash shell
    1. shell
  4. Set the SMB2Enabled Flag in likewise’s config:
    1. /opt/likewise/bin/lwregshell set_value '[HKEY_THIS_MACHINE\Services\lwio\Parameters\Drivers\rdr]' Smb2Enabled 1
  5. You can verify the values with the following command:
    1. /opt/likewise/bin/lwregshell list_values '[HKEY_THIS_MACHINE\Services\lwio\Parameters\Drivers\rdr]'
  6. Then restart likewise:
    1. /opt/likewise/bin/lwsm restart lwio

Now the vCSA will use SMB2! This can be required if you have security policy requiring the disablement of SMB1.
