DHCP and PXEboot question
Wanted to run something past you guys in the hope that you would be able to tell me if itís just how it needs to be or thereís something wrong with our configuration.
If I want to use PXEboot to deploy images out, I have to let our network guys know in advance so they can lower the IP lease time from the normal 2 weeks to about 5 hours. This they say is because when I deploy using PXEboot, the computer ends up with 2 IPs. One given to PXE and the other to the OS once installed. Even if PXE is switched off on the computer after deployment, the PXE apparently still holds onto the IP. Resulting in some of the subnets running out of IPs for the DHCP to distribute.
I would have thought the DHCP would be clever enough to know a computerís MAC addy is already assigned an IP and not give it a second. My network/server guys tell me if I leave PXEboot on in the BIOS the machine ends up being assigned multiple IPs! I just didnít think that sounded correct.
Iíve never heard of anyone else having to do this and wondered what other people do?
