Event ID 1065 — DHCP Scope Configuration

  • Article

Applies To: Windows Server 2008

Before Dynamic Host Configuration Protocol (DHCP) clients can use a DHCP server for dynamic Transmission Control Protocol/Internet Protocol (TCP/IP) configuration, you must define and activate scopes for your DHCP clients. A scope is the full, consecutive range of possible Internet Protocol (IP) addresses for a subnet. The IP addresses in a scope defines a single subnet on which DHCP services are offered. DHCP servers use scopes to manage network IP address distribution and the configuration of DHCP options.

Resolve

Reconcile the DHCP scope

In the DHCP snap-in, reconcile the DHCP scope.

To perform these procedures, you must be a member of the Administrators group, or you must have been delegated the appropriate authority.

To reconcile a DHCP scope:

  1. At the DHCP server, click Start, point to Administrative Tools, and then click DHCP.
  2. In the console tree, click the scope you want to configure.
  3. On the Action menu, click Reconcile.
  4. In the Reconcile dialog box, click Verify.
  5. If the verification indicates that the scope is consistent, click OK.
  6. If the scope is not consistent, select the displayed IP addresses that need to be reconciled, and then click Reconcile to repair inconsistencies.
  7. Ensure that there are no discrepancies in the options, classes, or other information configured for each scope.

Verify

To perform these procedures, you must be a member of the Administrators group, or you must have been delegated the appropriate authority.

To verify that DHCP scopes are configured properly and reconciled, confirm that the DHCP snap-in displays the green up arrow icon for Scope:

  1. At the DHCP server, click Start, point to Administrative Tools, and then click DHCP.
  2. In the console tree, click the scope you want to verify. The green up arrow icon should be displayed.
  3. On the Action menu, click Reconcile.
  4. In the Reconcile dialog box, click Verify.
  5. If the verification indicates that the scope is consistent, click OK.
