Description

On our internal MS DHCP servers PXEClient is set to PXEClient (probably pretty common). This makes from what I understand make the pxe boot rom try to contact the dhcp server on port 4011 to obtain the boot file. This fails and the machine will not pxe boot.

I have created a pull request which tries to mitigate this issue by setting option 60 to empty string for the reservation.

Hi Guys,

I opened a ticket for another MS dhcp issue: http://projects.theforeman.org/issues/5995. It seems that this fix broke my ms dhcp configuration. On my MS Dhcp Windows 2008 R2 there is no option 60. Since the option doesn't exist, the smart proxy was failing to create the dhcp entry. Can you maybe change the code so that the option is only set if available?
