Windows 2000 / XP WNTIPCFG

When your Windows NT/2000/XP system is configured to use DHCP or Automatic IP Generation,
you sometimes have to check/verify the IP-address assigned to your system and sometimes you
need manually request your Windows system to request a new IP-address from the DHCP-server
(which can be the case when traveling with a notebook computer from one office to another office and the notebook
"remembers" the IP-address of the previous office, not working in the new office unless it got instructed to "release"
the old IP-address and to request a new IP-address from the DHCP-server in the new office).

This is a simple and easy job on Windows95/98/ME using "winipcfg", while it is a little
more complex on Windows NT4/2000/XP, which does not include "winipcfg" :

It is required to use : "IPCONFIG"
- select from your Start-Menu: "Programs" / "Accessories" / "Command Prompt",
- enter: IPCONFIG
Sample Reply:

Windowss 2000 IP Configuration
Ethernet adapter Local Area Connection:
Connection-specific DNS Suffix . :
Autoconfiguration IP Address . . :
Subnet Mask . . . . . . . . . . . . . . :
Default Gateway . . . . . . . . . . . .:

Note the info, that the IP-address has been generated by the "Autoconfiguration", not via DHCP.
( IPCONFIG can also be used to request a new IP-address: to ReNew the IP-address )

Windows XP allows to check the IP-address
via "Network Connections" by displaying
the "Status" of a connection
( right-click the connection , pop-up menu ) :

tab : Support

You can avoid using the command-line and "ipconfig" by downloading from Microsoft
the equivalent of "winipcfg" for Windows NT/2000/XP : "wntipcfg"
(which is part of the Windows 2000 Resource-kit and available online for download) :
(location of the link on Dec.14,2002, if the link does not work anymore, then please search the Microsoft
website for "wntipcfg"):

Once you have downloaded the installation files and executed them, then "wntipcfg"
is available under "Program Files\Resource Kit":

"wntipcfg" is working exactly as "winipcfg":

You can view your IP-configuration,
release an IP-address and request
to get a new IP-address assigned
to your system ("Renew").

"wntipcfg" works properly on Windows XP.
