In win2k just type :
devmgmt.msc

if that does not the trick just try this
mmc c:\winnt\system32\devmgmt.msc

if your win2k is in your C drive and your win2k directory
is winnt and so on ....

DEVCON: COMMAND-LINE UTILITY
SIMILAR TO DEVICE MANAGER
--------------------------------------------------
The DevCon utility is a command-line utility that acts as an alternative to
Device Manager. It allows individual devices or groups of devices to be
enabled,
disabled, restarted, updated, removed, and queried. DevCon provides
information
relevant to the developer that is not available in Device Manager.
DevCon has been designed for use on Windows XP and Windows 2000. It will not
work on Windows 95, Windows 98, or Windows Millennium Edition.
DevCon is available as a debugging and development tool. It can be freely
modified for private use. The source code and documentation for DevCon can
be
found in the Windows XP DDK under %DDKroot%\Src\Setup\Devcon. The sample
demonstrates how to use the SetupAPI and CfgMgr32 APIs together effectively
to
enumerate devices and perform device operations.
Note: The DevCon utility may not be redistributed.
Detailed information and a link to the DevCon.exe file are available in
Knowledge Base at:
