I have a 2008 server that I have set to use a dhcp reserved ip address. The dns record keeps getting deleted, i keep having to re-create it. Has anyone seen this before and what did you guys do to fix it? Thanks

    Check the scavenging time on the DNS Zone.  Verify that it isn't set to something small that's less then the lease time of the DHCP assigned IP Address.

    If the above is not the cause then please use ADSIEdit.msc to see if you have a duplicate zone (caused by manually populating DNS on a DC instead of allowing the replication process to auto-populate). This blog explains exactly what to look for and the section you are looking for is

    Why not use a static address without the reservation?

    Look through that servers event logs for the following

    There should be some type of event stating that it couldn't auto-update. Also if you've enabled secure updates only then this is only going to work on a domain member
