Syslinux - Mar 2007 - pxelinux: Doing DHCP-Release?

Hi,

i am currently working on a project to install our windows-workstations
using PXE-Boot und unattended (http://unattended.sourceforge.net/).

All workstations load pxelinux and display a menu: Continue the bootchain
(= start Windows) or reinstall the Workstation.

The windows-workstations have static IPs (this can not be changes that
easy, we are talking about more then 5000 Workstations....)

There is also a very limited DHCP-Range, which could not be extended.
(because of the subnet / IP-concept), for mobile Divices (Laptops, PDAs,
...)

Now here is my problem:

When using PXE, every Workstation would use a DHCP-Lease to boot and a
static IP when Windows is running.

This will overfill the DHCP-Range and distroy the hole IP-Concept.

So here is my question:

Is there any way to get pxelinux doing a DHCP-Release?

Great Thanks

static IPs assigned via the DHCP server?

have the DHCP server issue the static IP to the Workstation.

if you give the Workstation it's static IP address via DHCP, you don't
need PXE to do that :)
