Query MAC Address

This feature allows you to query a remote computer’s MAC address

There are three ways to query a computer’s MAC address with the VNC Manager:

  • Use the Query MAC Address form.
  • A computer’s MAC address can be displayed as a column in the Registered Computers list.
  • You can also click on the Query MAC Address button in the Registered Computer’s properties dialog.

"Query MAC Address" Form

To open the Query MAC Address form, right click on a Registered Computer’s listing and select Computer Management Tasks -> Query MAC Address command. Alternatively you can use Ctrl+Shift+W as a shortcut to open the form.

The numbered items apply to the numbers shown in the picture at right:

  1. Target computers list.
  2. Allows you to specify a method to query a computer’s MAC addressby either using ARP or the WMI method. Both methods have their pros and cons.
    Method Name Pros Cons
    ARP query
    • Extremely fast.
    • Doesn't require logon credentials in order to establish a connection with a remote computer.
    • Only works on the network segment you are using ARP on.
    • Works with IPv4 addresses only.
    WMI query
    • Works with remote computers located on any network segment.
    • If the remote computer has more than one network adapter installed, the WMI method allows you to select which network adapter’s MAC address you want to get.
    • Works with IPv4 and IPv6 addresses.
    • Slower than the ARP method.
    • In order to establish a WMI connection you might be prompted to provide logon credentials.

The VNC Manager can query a computer’s MAC address using the Check VNC/RDP/SSH Server Status (Ctrl+U) command. The VNC Manager will attempt to retrieve a computer’s MAC address only if the following setting is enabled: Tools -> Options -> Server Status Check -> Resolve MAC address.
