# Getmac.exe: GetMAC

GetMAC provides a quick method for obtaining the MAC (Ethernet) layer address and binding order for a computer running Windows 2000, locally or across a network. This can be useful when you want to enter the address into a sniffer, or if you need to know what protocols are currently in use on a computer.

## Getmac.exe Examples

When you type:

`C:\>getmac \\host`

you get the following information returned:

`Information for machine \\host` `Transport Address Transport Name` `----------------- --------------` `00-00-1B-16-78-76 \Device\NetBT_NE32007` `00-00-1B-16-78-76 \Device\NwlnkNb` `00-00-00-00-00-00 \Device\NetBT_NdisWan5` `52-41-53-48-00-01 \Device\Nbf_NdisWan4` `52-41-53-48-00-04 \Device\Nbf_NdisWan8` `00-00-1B-16-78-76 \Device\Nbf_NE32007`

In this example 00-00-1b-16-78-76 is the address of an NE3200 Ethernet card, and 00-00-00-00-00-00, 52-41-53-48-00-01, and 52-41-53-48-00-04 are RAS addresses.

When attempting a connection to a remote computer over the network, the workstation service will use the following order:

NetBT (TCP/IP) over the NE3200

NwlinkNb (IPX) over the NE3200

NetBT over one of the RAS links

Nbf (NetBIOS) over two other remote access server links

Nbf over the NE3200

To change the order in which Windows 2000 attempts connections for the workstation service

1. In Control Panel, double-click Network.
2. Click Bindings.
3. In "Show Bindings For," select "Workstation."
4. Adjust the binding order by using the arrows on the right.
