How to check which SMB Version is enabled on Windows Server 2008 R2

I want to find which version of SMB is enabled on Windows Server 2008 R2.

I used the following command in PowerShell to know the smb versions installed: 

sc.exe qc lanmanworkstation

In its output, the DEPENDENCIES shows two versions of SMB:

Now the confusion is out of 2 versions installed, which SMB version is enabled on my server? As Server 2008 R2 does not support Get-SMBConnection I am unable to determine the specific version.

I have also check the registry path, and there is no entry about SMB version.

HKEY_LOCAL_MACHINE\\SYSTEM\CurrentControlSet\Services\LanmanServer\Parameters

Can anyone please tell me how to determine which SMB version is enabled on server if SMB versions are more than one?

To answer your question. Since you found out that the Get-SMBConnection is not supported at win2008R2 the best way is to find out which drivers are running:

I have used our win2008R2 to check (see below example). If you find out that the STATE is 4 RUNNING than the version of smb is active and "running"

PS U:\> sc.exe query mrxsmb10

SERVICE_NAME: mrxsmb10
        TYPE               : 2  FILE_SYSTEM_DRIVER
        STATE              : 4  RUNNING
                                (STOPPABLE, NOT_PAUSABLE, IGNORES_SHUTDOWN)
        WIN32_EXIT_CODE    : 0  (0x0)
        SERVICE_EXIT_CODE  : 0  (0x0)
        CHECKPOINT         : 0x0
        WAIT_HINT          : 0x0

PS U:\> sc.exe query mrxsmb20

SERVICE_NAME: mrxsmb20
        TYPE               : 2  FILE_SYSTEM_DRIVER
        STATE              : 4  RUNNING
                                (STOPPABLE, NOT_PAUSABLE, IGNORES_SHUTDOWN)
        WIN32_EXIT_CODE    : 0  (0x0)
        SERVICE_EXIT_CODE  : 0  (0x0)
        CHECKPOINT         : 0x0
        WAIT_HINT          : 0x0

That means that both SMB versions are active and running.
