Set the authentication method

  • Article

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

To set the authentication method

  • Using the Windows interface

  • Using a command line

Using the Windows interface

  1. Open POP3 service.

  2. In the console tree, right-click the computer_name node and click Properties.

    Where?

    • POP3 Service/computer_name

  3. In Authentication Method, click the drop-down menu, and then click the authentication method you want to use.

Important

  • You can change the authentication method only if there are no existing domains defined. If there are existing domains, the option to change the authentication method is disabled.

    If you change this parameter, you must stop and restart the POP3 service and the IIS Admin service. For more information on how to change the POP3 service state and start and stop the IIS Admin service, see Related Topics.

Notes

  • To perform this procedure, you must be a member of the Administrators group on the local computer, or you must have been delegated the appropriate authority. If the computer is joined to a domain, members of the Domain Admins group might be able to perform this procedure. As a security best practice, consider using Run as to perform this procedure.

  • To open the POP3 service snap-in, click Start, click Control Panel, double-click Administrative Tools, and then double-click POP3 Service.

  • If the computer on which the POP3 service is running is either a member of an Active Directory domain or a domain controller, the default authentication method is Active Directory integrated authentication. If the computer is not in a domain, the default is local Windows accounts authentication.

  • If the computer on which the POP3 service is running is a domain controller, the available authentication methods are Active Directory integrated authentication and encrypted password file authentication. If the computer on which the POP3 service is running is a member server in an Active Directory domain, all three authentication methods are available. Otherwise, the available authentication methods are local Windows accounts authentication and encrypted password file authentication.

  • If you are using Active Directory integrated authentication, you must log on to the Active Directory domain, not the local computer, to perform this procedure.

Using a command line

  1. Open Command Prompt.

  2. Type:

    winpop set {authentication|auth} {1|2|3}

Value Description

winpop set {authentication|auth}

Sets the type of authentication to be used by the POP3 service. The auth command provides the same functionality as authentication.

{1|2|3}

Specifies the authentication method POP3 uses to verify users who connect to the mail server. The available authentication methods vary, depending on the configuration of your server.

  • If the computer on which the POP3 service is running is an Active Directory domain controller, the values are as follows:

    1 - Active Directory integrated authentication

    2 - Encrypted password file authentication

  • If the computer on which the POP3 service is running is an Active Directory member server, the values are as follows:

    1 - Active Directory integrated authentication

    2 - Local Windows accounts authentication

    3 - Encrypted password file authentication

  • Otherwise, the following values apply:

    1 - Local Windows accounts authentication

    2 - Encrypted password file authentication

Important

  • You can change the authentication method only if there are no existing domains defined. If there are existing domains, the option to change the authentication method is disabled.

    If you change this parameter, you must stop and restart the POP3 service and the IIS Admin service. For more information on how to change the POP3 service state and start and stop the IIS Admin service, see Related Topics.
