Reservations deleted?

Hi,
Does anyone know of a way of seeing if dhcp reservations have been deleted by someone?
I have checked the dhcp logs and cannot see anything obvious.
Seemingly, they just disappeared when some in-house staff were doing work the weekend just gone, I don't think they did just disappear.
Cheers,

+1 I dont recall any default auditing that monitors erasure of DHCP reservations, or the like. You might be SOL on this one, man.

Regarding the question of knowing if DHCP Reservation have been deleted, i am sure, the only available source of DHCP error finding is through DHCP log, so that might be a good idea to look in the DHCP logging.

Thanks for the response. We do have an events manager server on our network, im not sure if that event type be logged though, I will run through it on Monday.
I have already tried the dhcp logs but can't find any info on reservation deletion.
Thanks again,
