Allow a computer to be trusted for delegation

Applies To: Windows Server 2003, Windows Server 2003 R2, Windows Server 2003 with SP1, Windows Server 2003 with SP2

To allow a computer to be trusted for delegation

  1. Open Active Directory Users and Computers.

  2. In the console tree, click Computers.


    • DomainName/Computers
  3. In the details pane, right-click the computer you want to be trusted for delegation, and click Properties.

  4. Do one of the following.

    • If in a Windows Server 2003 domain, on the Delegation tab, click Trust this computer for delegation to any service (Kerberos only), and then click OK.

    • If in a Windows 2000 native domain, click the General tab, click Trust this computer for delegation, and then click OK.


  • To perform this procedure, you must be a member of the Domain Admins group or the Enterprise Admins group in Active Directory, or you must have been delegated the appropriate authority. As a security best practice, consider using Run as to perform this procedure. For more information, see Default local groups, Default groups, and Using Run as.

  • To open Active Directory Users and Computers, click Start, click Control Panel, double-click Administrative Tools, and then double-click Active Directory Users and Computers.

  • If you cannot see the Delegation tab, do one or both of the following:

    • Register a Service Principal Name (SPN) for the computer account using the Setspn utility in the support tools that are on your CD. Delegation is only intended to be used by service accounts, which should have registered SPNs, as opposed to a regular user account, which typically does not have SPNs.

    • Raise the functional level of your domain to Windows Server 2003 . For more information, see Related Topics.

  • For security reasons, do not allow servers on the enterprise network to perform delegation at will on behalf of any network connection.

Information about functional differences

  • Your server might function differently based on the version and edition of the operating system that is installed, your account permissions, and your menu settings. For more information, see Viewing Help on the Web.
