How to do ipconfig release/renew remotely, with an admin credentials?

Hi

Is there any way/script to release and renew ip address of multiple
machines remotely?
Details: We have around 40 machines in a LAN. Every day, at a
particular time, these machines are used by different user, for
different kind of work so we have to switch these machines' vlan
(because these users have totally different set of requirements) and
need to release their currnet ip and get a new ip (from new vlan) by
renewing it. Both the vlans have DHCP configured. I am able to release
all the machines' ip addresses (using psexec utility) but as the ip has
released, I am loosing the connection to all these machines and am not
able to renew it.
Server: Windows Server 2003
Machines: Windows XP Professional

Another problem is, these users have limited authority so I can not run
any script on these machines without passing administrative
credentials. RunAs command only takes username but not the password so
its not useful in this case.

Please someone suggest me a way to do this job remotely and avoid
manual work.

Thanks in advance.

Of course you're going to lose connection when the computer's IP is released.
It sounds like you really need to find another solution, such as using a
hardware profile for each VLAN.

Another option would be to use a simple batch file (launched remotely) that both
releases and renews the IP.
