1.3.1 Server Roles

With both PATHWORKS Advanced Server and PATHWORKS LAN Manager, primary and backup domain controllers are similar in concept; however, they interoperate differently in the PATHWORKS Advanced Server environment. For example:

PATHWORKS Advanced Server may be configured as a primary or backup domain controller. Standalone and member server roles are no longer supported.

1.3.2 Trust Relationships

The PATHWORKS Advanced Server introduces the implementation of trusts into the domain, similar to Windows NT Server software. You can set up trust relationships to allow users from other domains to access resources in the local domain, and local domain users may access resources in other domains. To do this, you must establish the trust relationship in both domains using domain trust passwords.

Refer to the Advanced Server for OpenVMS Concepts and Planning Guide for more information about trust relationships.

1.3.3 Users and Groups

Both PATHWORKS Advanced Server and LAN Manager servers support user groups, which are sets of users who share common permissions for one or more resources. Placing users into groups makes it easier and faster to grant multiple users access to a resource, and it simplifies network administration.

The PATHWORKS Advanced Server supports two types of groups: global and local. The following table describes their differences.

Table 1-2 Local and Global Group Differences
Global Groups Local Groups
Can be used to grant permission to objects on the local domain and other domains. Can be used to grant permission to objects in the local domain only.
Can contain only user accounts from its own domain. Can contain user accounts and global groups both from the local domain and from trusted domains.
Provides a way to create sets of users from only inside the local domain, available for use both to local and other domains. Enable you to create convenient sets of users from both inside and outside the domain.

For more information about local and global groups, see the Advanced Server for OpenVMS Concepts and Planning Guide.

1.3.4 Server Administration

PATHWORKS LAN Manager provides a character-cell interface called ADMIN/PATH and the industry standard Net Admin command line interface. PATHWORKS Advanced Server provides a comprehensive DCL-conforming command line interface called ADMINISTER.

The PATHWORKS Advanced Server software package also includes Windows NT server administration tools. New Command Line Interface

The PATHWORKS Advanced Server provides a new command line interface for managing PATHWORKS Advanced Server. The new interface conforms to standard DCL command syntax, and replaces the LAN Manager Net command line interface. For backward compatibility purposes, the new command line interface supports command translation for a subset of the Net commands.

To use the new command line interface, log in as the system administrator, then enter the following command at the OpenVMS prompt:


The //domain/server> prompt shows the current domain name and server name. For online information, enter the HELP command.

Refer to the PATHWORKS for OpenVMS (Advanced Server) Server Administrator's Guide and the Advanced Server for OpenVMS Commands Reference Manual for more information about the ADMINISTER command interface. Windows NT Server Administration Tools

You can remotely manage the PATHWORKS Advanced Server using the Windows NT server administration tools provided with the Windows NT Server. These administration tools are included in the PATHWORKS Advanced Server software kit for you to install on Windows 95, Windows NT, or Windows for Workgroups workstations. You can use these tools to manage the PATHWORKS Advanced Server from any computer within the domain.

The Windows NT server administration tools are generic network administration tools, including:

For more detailed information, see the Windows NT Server product documentation.

1.3.5 Security

The PATHWORKS Advanced Server employs a user-level security model. User-level security provides precise control over access to shared resources, including disk devices, directories, and printers, basing its control on a password assigned to each user account. PATHWORKS Advanced Server security implementation is described as follows:

For more information on PATHWORKS Advanced Server security, refer to the Advanced Server for OpenVMS Concepts and Planning Guide. Resource Permissions

Like PATHWORKS LAN Manager permissions, the PATHWORKS Advanced Server permissions can work in concert with standard OpenVMS file system protections. In addition, PATHWORKS Advanced Server allows you to apply a virtually unlimited number of user:permission or group:permission pairs to any file, directory, or resource.

Refer to the Advanced Server for OpenVMS Concepts and Planning Guide for detailed information on permissions. Share Security

Like Windows NT Servers, the PATHWORKS Advanced Server does not support share-level security and operates in user-level security mode only. Share passwords are not required with the PATHWORKS Advanced Server. User accounts are granted access to resources based on their user account information and group membership.

You can set individual permissions for share access, however it is much easier to administer group permissions.

The recommended steps for granting user access to PATHWORKS Advanced Server shares are:

  1. Modify the share to allow group access.
  2. Assign users to the appropriate group.

For more information about PATHWORKS Advanced Server security, see the Advanced Server for OpenVMS Concepts and Planning Guide.

1.4 LAN Manager Features That Are Not Supported

This section summarizes the PATHWORKS LAN Manager features that are not supported with PATHWORKS Advanced Server:

1.5 Client Impact

The PATHWORKS Advanced Server is compatible with LAN Manager client software. Although LAN Manager servers need to be upgraded to benefit from PATHWORKS Advanced Server functionality, there is no need to change the networking software on each desktop. Users can benefit immediately from the new resources offered by the PATHWORKS Advanced Server without additional training because there is no change in the way users access network resources.

PATHWORKS Advanced Server supports connections from the following types of clients:


After upgrading, clients will have to reconnect to the server.

1.6 LAN Manager Impact

To migrate from PATHWORKS LAN Manager to PATHWORKS Advanced Server without disrupting service, install only the Upgrade utility first. You cannot continue to run the PATHWORKS LAN Manager software once the PATHWORKS Advanced Server server has been installed. Install the PATHWORKS Advanced Server server only after completing the upgrade of server information.

1.7 Server License Requirements

The PATHWORKS Advanced Server requires that clients accessing file and print services be appropriately licensed. To conform to this requirement, one of the following must be true:

In both cases, the license required to access PATHWORKS Advanced Server services is the PATHWORKS Client-Access license: PWLMXXXCA06.00.

Refer to Chapter 6, Completing the Migration, for a description of the procedure.

1.7.1 Options for Upgrading Client-Based Licenses

When you plan the migration from PATHWORKS LAN Manager to PATHWORKS Advanced Server, assess the environment and decide the best procedure to ensure clients who need to access the PATHWORKS Advanced Server are sufficiently licensed. Upgrade options for client-based licenses include:

These options are described in more detail in Configuring Clients, Removing PATHWORKS LAN Manager Licenses, and Configuring Automatic Upgrade in this guide.

1.7.2 Configuring Clients

Individually configuring specific clients to request a PATHWORKS Advanced Server license requires visiting the clients and modifying their configuration for the licenses the client requests. This procedure works best in the following situations:

The actual procedure for configuring clients varies depending on the client networking software. Refer to the Advanced Server for OpenVMS Guide to Managing Advanced Server Licenses for more detailed instructions.

1.7.3 Removing PATHWORKS LAN Manager Licenses

You can remove the PATHWORKS LAN Manager licenses from the license server system when you load the new PATHWORKS Advanced Server license PAKs. You remove licenses using the License Management Facility (LMF). After that, clients requesting server access will receive a PATHWORKS Advanced Server license.

When you remove a license, you revoke any previously assigned licenses. Therefore, when a client requests a license assignment or verification, the client is assigned a PATHWORKS Advanced Server license.

1.7.4 Configuring Automatic Upgrade

Configuring the PATHWORKS license server to upgrade licenses will affect all clients presenting or requesting a PATHWORKS LAN Manager license. If the PATHWORKS license server is configured to upgrade licenses, a PATHWORKS Advanced Server license is granted when either of the following occurs:

The PATHWORKS license server automatically assigns the client a PATHWORKS Advanced Server license (even though the client expects assignment or verification of a PATHWORKS LAN Manager license), and returns an equivalent PATHWORKS Advanced Server license to the client, if available.
