NOTE: We expect this environment to be relatively rare, as Active Directory was introduced with Windows 2000 Server.

In order to join a NetBIOS-based domain, the NAS must locate a "master browser" on the local subnet, and then locate the Domain Controller by way of the master browser. The master browser will normally be a Windows server on the same subnet as the NAS. In most environments, a properly configured WINS server can compensate for the lack of a master browser on the network segment.

Log messages will help with the troubleshooting process. "No master browser found for DOMAIN" indicates that no browser server was found. "locate failed" indicates that a domain controller was not found.

In order to see what NetBIOS devices were found on the network, check the NetBIOS cache (in the NAS diagnostics, described below) for the <1D> or <1B> tag with an IP matching your subnet. Double check the domain name used against the one in the NetBIOS tag of the master browser. It might be necessary to move the StorageTek[TM] 5320 NAS to the same subnet and segment as a master browser. All Windows server operating systems provide master browser services by default. Installing StorageTek 5320 NAS on the same subnet as a domain controller is the best practice when possible. Again, a WINS server that has a record of the Domain Controllers will resolve most browsing issues.

To check the NetBIOS Cache:

1. Connect to the Sun StorageTek 5320 NAS through Telnet or a serial console.
2. Press Enter at the [menu] prompt and type the administrator password.
3. Press the spacebar until Diagnostics displays under Extensions at the lower right.
4. Select the letter corresponding to Diagnostics. Wait a few seconds while the StorageTek 5320 NAS builds the diagnostic.
5. When the diagnostic is ready, you can page through it using the spacebar [space] and [b] keys, or you can email it or save it to a file.
6. In either case, search through the file for the heading "NETBIOS Cache". Note each of the NetBIOS tags. Each NetBIOS tag displays in the form Hostname<##> or Domain<##> with one or more IP addresses associated with each tag. <##> is a number expressing a particular NetBIOS service being advertised.

The NetBIOS tags important to Domain operations are as follows:

Hostname<00>: Local workstation service for the host name.
Hostname<20>: Local server service for the host name.
Domain<00>: Indicates inclusion in the domain or workgroup for the included IP address, but does not necessarily indicate domain membership.
Domain<1D>: Segment master browsers for the listed domain. This server provides browsing services for this domain only on this IP subnet.
Domain<1C>: Domain controller for listed domain. Either a primary (PDC) or backup domain controller (BDC).
Domain<1B>: Primary domain controller for listed domain. By definition, the browse master for its own subnet and the collector of all data from other browse servers.
