Script DHCP Lease period

I need a script to change the lease period for a DHCP scope on a windows 2003
server.

I have scripts to install DHCP and configure the scope and Options using
NETSH but there does not seem to be an option for changing the lease period
 
The lease period is controlled by the DHCP server, and that's where you
should be setting it.

Thanks Richard, I am aware of that but how do I set it using a script. I have
170 servers in remote offices and I need to change the lease period on all of
the by script

What about GPO's? Is there anyway a GPO can configure a DHCP Server? Are
these Server domain members?

The lease time is actually an option (it is just wrapped by the Scope
Properties in the snap-in).

You can change the lease time by changing the value of option 51. It is a
DWORD representing the length of the lease time in seconds.

If you make the change on your DHCP Server, then all the "script" you'll
need for the servers will be:

ipconfig /release
ipconfig /renew

This will query the DHCP server for an address and any optional settings you
have defined within the address range. If your current lease period is
short you won't need any script at all, since within half the time of the
current lease renewal all the servers should be updated.

Spot on thank you very much

You're welcome, and thanks to Doug Sherman, too, who actually posted this
info before I did, I just didn't notice his post. :-)
