Using netdiag from the Windows 2000 support tools, I have scripted NICSpeed.bat to answer the subject question.
NICSpeed has no arguments and returns two string environment variables:
NIC - is a text string that identifies the installed network adapter. Example: Intel 8255x-based PCI Ethernet Adapter (10/100) NICSpeed - is is a text string that identifies the Media Speed. Example: 100MbpsNOTE: I have made no attempt to handle multi-homed computers.
You can use workstation.bat to run a batch file that calls NICSpeed on all your workstations.
for /f "Tokens=*" %%i in ('netdiag /v') do @set string=%%i&call :parse
endlocal&set NIC=%NIC%&set NICSpeed=%NICSpeed%
if "%fnd%" EQU "y" goto nicinfo
if NOT "%string:~0,31%" EQU "Information of Netcard drivers:" goto :EOF
if "%string:~0,12%" EQU "Description:" set NIC=%string:~13,99%
if NOT "%string:~0,12%" EQU "Media Speed:" goto :EOF
set work=%work: =%
