Source facts

\n

Microsoft’s quickstart separates installing the DHCP role, authorizing it in Active Directory, and configuring an IPv4 scope with client options. The prerequisites include a supported Windows Server release, a static IPv4 address, a planned scope range, and administrative rights. An unauthorized DHCP server installed in an AD domain does not lease addresses properly; Microsoft identifies automatic disabling as a protection against unauthorized configuration. Microsoft documentation.

\n

Applicability

\n

Use this review for a new domain-based DHCP deployment. Identify the server address, approved client range, existing address assignments, and the administrator responsible for authorization. Keep installation success separate from service acceptance.

\n

DSE recommendation

\n

Have the network owner review the proposed scope and options against the address plan. Record the server identity that is to be authorized and verify it before making the directory change. Choose representative clients on the intended network segments and agree on the returned configuration they should receive. Preserve the approved plan with the server installation record.

\n

Verification

\n

Inspect role state, authorization, and the configured scope as separate checks. Test a client lease request and record the responding server, address, and supplied options. Compare these with the plan before adding more clients. Investigate authorization or scope errors individually rather than reinstalling the role as the default response.
