7 Tools for special tasks

Advanced Server for UNIX contains tools for the system administrator, which need only be used in special cases. These tools are described in the sections that follow in relation to particular application scenarios. It is recommended that you first of all read the description of the PC tools and then the description of the tools for NetBIOS, as well as other system administration tools. Finally you should read the information provided in relation to support high availibility configurations.

7.1 PC tools

The following tools are contained in the DOSUTIL resource:

7.1.1Searching for the Master Browser for a domain in a subnetwork (findbrow.exe)

This tool helps you to find the Master Browser in a subnetwork. This is of benefit to the system administrator when searching for errors.

Syntax:
