| DHCP server is not authorized in AD | When configured correctly and authorized for use on a network, Dynamic Host Configuration Protocol (DHCP) servers provide a useful administrative service. However, a misconfigured or unauthorized DHCP server can cause problems. For example, if an unauthorized DHCP server starts, it might begin either leasing incorrect IP addresses to clients or negatively acknowledging DHCP clients that attempt to renew current IP address leases. To resolve these issues, DHCP servers are verified as authorized in Active Directory Domain Services before they can service clients.
