For example, some folks believe that the DNS servers or other DCs not be running DHCP should be in it. Make sure that NO user accounts are in that group, either.

(I hope that’s crystal clear – you would be surprised on the number of responses I get asking if the DHCP credentials should be in this group.) You Just to be crystal clear, this means that if the lease is an 8 day lease, than NOREFRESH should be 4 (four) and REFRESH should be 4 (four) so when you add them together, they are not greater than the lease length.

You must delete them manually to allow DHCP to take care of all new records moving forward. DHCP will give that duplicate named client an IP, but it will not register it into DNS.

Also, it will allevaite another issue – If DHCP is on a DC, it will not overwrite the original host record for a machine getting a new lease with an IP previoulsy belonging to another host. Quoted from the following link: “Name squatting occurs when a non-Windows-based computer registers in Domain Name System (DNS) with a name that is already registered to a computer running a Windows® operating system.

This is because the client will not update itself due to the current record in DNS is beyond the lease period.

This happens even though DHCP registered the record.

By default, the ACL gives Create permission to all members of the Authenticated User group, the group of all authenticated computers and users in an Active Directory forest.

Please understand, the main thing that scavenging works on is the timestamp.

This is because DHCP doesn’t own the record, the client does, even though DHCP registered it.
