In both Windows NT and OS/2 Warp,
the MacAddress of your computer's network adapter can be found using the
NET CONFIG command.
I will try to explain an NT "batch file" (one command line, actually)
that will do just that on this page.
The complete "source" can be found at the
end of this page.
The OS/2 Warp version will not be
explained. I created it just for fun, to see if it were possible.
However, since I needed a lot of "dirty tricks" to replace NT's FOR
options, I think Rexx would have been more suited for this task.
The Windows 95/98 version uses
NBTSTAT -a to get the MacAddress.
The latest addition is a DOS version
by Robert L. Baer.
It is meant for MS Client 3.0, the MS network client for MS-DOS, used
mainly in network boot diskettes for unattended installs.
In NT, typing NET CONFIG will display a result like this:
The following running services can be controlled:
Server
Workstation
The command completed successfully.
Typing NET CONFIG SERVER will display something like this:
Server Name \\MYSERVER
Server Comment
Software version Windows NT 4.0
Server is active on NetBT_W30NT1 (002000123ABC) NetBT_W30NT1 (002000123ABC) Nbf_W30NT1 (002000123ABC)
Server hidden No
Maximum Logged On Users Unlimited
Maximum open files per session 2048
Idle session time (min) 15
The command completed successfully.
Whereas typing NET CONFIG WORKSTATION will display something like this:
Computer name \\MYSERVER
User name Administrator
Workstation active on NetBT_W30NT1 (002000123ABC) Nbf_W30NT1 (002000123ABC)
Software version Windows NT 4.0
Workstation domain MYDOMAIN
Logon domain MYDOMAIN
COM Open Timeout (sec) 3600
COM Send Count (byte) 16
COM Send Timeout (msec) 250
The command completed successfully.
As you can see, the parameters we used for NET CONFIG were the ones supplied by the NET CONFIG command itself.
We can use this to extract all NET CONFIG information at once for any PC running NT, either server or workstation:
@ECHO OFF
FOR /F %%A IN ('NET CONFIG ˆ| FIND /V ":" ˆ| FIND /V "."') DO (
ECHO ______________
ECHO.
ECHO %%A
ECHO ______________
ECHO.
NET CONFIG %%A
)
Or, if you prefer the command line:
@FOR /F %A IN ('NET CONFIG ˆ| FIND /V ":" ˆ| FIND /V "."') DO @ECHO ______________ & ECHO. & ECHO %A & ECHO ______________ & ECHO. & NET CONFIG %A| Notes: | (1) | By using
FIND /V ":" ˆ| FIND /V "."
the "header" and "footer" lines are removed, in a language independent way.You may want to add FIND " " to remove the empty lines too. |
| (2) | In case your browser doesn't display this the right way: the character preceding the pipe symbol (|) is a caret (^). It is the escape character for the NT command line. |
The output will look like this:
______________
Server
______________
Server Name \\MYSERVER
Server Comment
Software version Windows NT 4.0
Server is active on NetBT_W30NT1 (002000123ABC) NetBT_W30NT1 (002000123ABC) Nbf_W30NT1 (002000123ABC)
Server hidden No
Maximum Logged On Users Unlimited
Maximum open files per session 2048

The command completed successfully.

You may combine this example with one or more FIND
based filters plus FOR /F to extract any network
related information you want.
The network adapter's MacAddress, for example:
@ECHO OFF
FOR /F %%A IN ('NET CONFIG ˆ| FIND /V ":" ˆ| FIND /V "."') DO FOR /F "TOKENS=2,3 DELIMS=()" %%X IN ('NET CONFIG %%A ˆ| FIND " active "') DO SET MacAddress=%%X
ECHO MacAddress=%MacAddress%
