Windows 2000 clients hold dhcp address when booting on different network

[Mark Leddy]

We have several users who use a laptops in the office and then connect
them on different networks either home networks, Comcast broadband, at
anther site, etc. that are finding when the Windows 2000 laptops are
booting up (even from a full shutdown) with the old ip address. (from
the other network's DHCP server).

The network connection show as connection on the system tray.

Running ….
ipconfig /release
ipconfig /renew

Corrects the issue however, we want to avoid giving the users admin
rights which mean they cannot perform this.

Thank you,
Mark

The article is for win98, but it might work for win2000 too

Alas,
http://support.microsoft.com/defaul...port/kb/articles/q271/4/55.asp&NoWebContent=1
states that 'No such functionality exists for Windows NT'

An alternative could be to implement a simple DLL along the lines of
http://www.codeproject.com/system/winlogon_notification_package.asp

When the user logs off, have this .dll execute IpReleaseAddress
(http://msdn.microsoft.com/library/default.asp?url=/library/en-us/iphlp/iphlp/ipreleaseaddress.asp).

The function will run as admin (same rights as winlogon.exe). That way you
don't have to give users admin rights
