For more information about changing configuration settings, see Section 3.6, How to Change Server Configuration Settings.

For more information about each server configuration setting, refer to the Compaq Advanced Server for OpenVMS Server Administrator's Guide.

3.3.4 What Do You Want the Administrator Account Password to Be?

If you are configuring a PDC, the configuration procedure prompts you to specify the password to be set for the domain Administrator account. If you are configuring a member server, the configuration procedure prompts you for the member server's local Administrator account password to be set. The member server's local Administrator account password gives access to the member server's local security account database. As with Windows NT, there may be situtations where you would like to allow certain people to manage a member server's local database without giving them the ability to manage the entire domain.

Passwords are case sensitive and can contain up to 14 characters. Valid characters are alphanumeric characters and any of the following special characters:

! # $ % & () - . ^ _ ` { } ~

3.3.5 Are You Going to Supply Account/Password Information?

If you are configuring your server to join an existing domain (as a BDC or member server), you can either:

• Have the computer added to the domain manually by the domain administrator
• Have the computer added by supplying an administrator account user name and password during execution of the configuration procedure

The former option is useful if the domain administrator does not wish to give out the user name and password of the Administrator account in the domain to the person configuring this server to join the domain. The domain administrator can use the ADMINISTER ADD COMPUTER command or the Windows NT Server Manager to add the computer to the domain. If this is the case, answer NO to this prompt, and you will not be prompted for account/password information.

With the latter option, the configuration procedure requests the domain's PDC to add the computer to the domain. You will be prompted for a domain administrator account user name and password, as explained in Section 3.3.6, What Is the Domain Administrator Password?.

3.3.6 What Is the Domain Administrator Password?

When you choose to have the computer added automatically by the configuration procedure, you are prompted for a domain administrator account user name and password. As noted in Section 3.3.5, Are You Going to Supply Account/Password Information?, the PDC is requested to add the computer to the domain. The PDC validates the account user name and password on behalf of the configuration procedure. Enter the password, observing the rules specified in Section 3.3.4, What Do You Want the Administrator Account Password to Be?.

3.3.7 Do You Want to Enter a New Administrator Account Password?

In certain cases, you are prompted whether you want to enter a new Administrator password. This gives you the opportunity to change the password.

3.3.8 Do You Want to Start the Server?

The configuration procedure asks you if you want to start the Advanced Server. If you do not want to start the Advanced Server at this time, you can do so later from the command line after the configuration procedure completes.

Before you start the server on any OpenVMS Cluster member, Compaq recommends that you configure the Advanced Server on each cluster member that you want to use as a server. You can then use the SYSMAN utility to start the server on all cluster members. If you choose to start the server individually on each cluster member, make sure that you do so from the SYSTEM account (or a similar account) on each server node. For more information, see Section 5.4.3, How to Start the Advanced Server in an OpenVMS Cluster.

3.4 How to Start the Advanced Server Configuration Procedure

After the installation procedure completes, the OpenVMS system prompt ($) is displayed.

1. Ensure that you are logged in to the SYSTEM account.
2. Start the configuration procedure by entering:

Depending on the domain type, the Advanced Server can participate in a domain as either the PDC, a BDC, or a member server.

There are three kinds of domains that the Advanced Server may participate in:

• Windows NT domains, in which Advanced Servers can participate as a PDC, BDCs, and member servers
• Windows 2000 mixed-mode domains, which are domains that include both Windows 2000 domain controllers and Windows NT or Compaq Advanced Server domain controllers; Advanced Servers can participate as BDCs and as member servers
• Windows 2000 native-mode domains (also referred to as a pure Windows 2000 domains), which are domains in which all domain controllers are Windows 2000 systems; Advanced Servers can participate as member servers only

Table 3-3, Server Roles in Each Type of Domain, lists for each type of domain the roles the server can take:

Table 3-3 Server Roles in Each Type of Domain

For Domain Type:	The Advanced Server Can Take These Roles:
	PDC	BDC	Member Server
Windows NT	X	X	X
Windows 2000 Mixed-Mode		X	X
Windows 2000 Native-Mode			X

Each Windows NT domain must have one PDC. The PDC stores the domain's master copy of the security accounts database.

When you install the Advanced Server to create a new Windows NT domain, the new server becomes the PDC by default. When you install server software and specify an existing domain name, the server can join the existing domain only as a BDC or member server.

A domain does not have to have BDCs, but one or more are recommended. A BDC keeps a copy of the domain's master security accounts database. The copy of the security accounts database stored on BDCs is synchronized with the PDC's master database. PDCs and BDCs can validate logon requests in the domain.

A member server does not store a copy of the domain's security accounts database and does not validate logon requests. Member servers rely on domain controllers to validate credentials of users requesting access to member server shares. The advantages of configuring the Advanced Server as a member server are listed in Section 3.7.1, Configuring the Advanced Server As a Member Server.

In an OpenVMS Cluster, all nodes on the cluster must have the same role. If you change the role of one node, the other nodes are automatically changed to the same role.

When you configure the Advanced Server for the first time, you select the role your server will perform in the domain. There may be times when you need to change the role of your server. The method you use to change the server depends on the current role of the server and the role you want to change it to. To change the role of the server from a BDC to a PDC, or vice versa, use the ADMINISTER SET COMPUTER/ROLE command. To change a server BDC to a member server, you must use PWRK$CONFIG, as explained in Section 3.7.1, Configuring the Advanced Server As a Member Server. To change a PDC to a member server, you must first promote another BDC to a PDC; then the original PDC is demoted automatically to a BDC, after which you can use PWRK$CONFIG to change it to a member server. Use PWRK$CONFIG also to change a member server to a BDC. (This restriction is similar (but less restrictive) to that of Windows NT, which requires the operating system to be reinstalled to change a domain controller to a member server, or vice versa.) For more information on changing the role of the server from a BDC to a PDC, or vice versa, refer to the Compaq Advanced Server for OpenVMS Server Administrator's Guide. Table 3-4, Methods for Changing Server Roles, summarizes which role changes are allowed and disallowed by PWRK$CONFIG.

Table 3-4 Methods for Changing Server Roles

From:	To:	Method
BDC	PDC	Use ADMINISTER SET COMPUTER/ROLE command to promote the BDC to a PDC
BDC	Member	Use PWRK$CONFIG
Member	PDC	Use PWRK$CONFIG to change this server to a BDC, and then use the ADMINISTER SET COMPUTER/ROLE command to promote the BDC to a PDC
Member	BDC	Use PWRK$CONFIG
PDC	BDC	Use ADMINISTER SET COMPUTER/ROLE to promote a BDC in the domain to PDC; this promotion demotes the original PDC to a BDC
PDC	Member	Use ADMINISTER SET COMPUTER/ROLE to promote an existing BDC to a PDC; this promotion demotes the PDC to a BDC so that you can change it to a member server, using PWRK$CONFIG
