NAME

na_cifs_testdc - test the Filer's connection to Windows NT domain controllers

SYNOPSIS

cifs testdc [ domainname ]

cifs testdc [ WINSsvrIPaddress ] domainname [ filername ]

DESCRIPTION

The cifs testdc command tests the Filer's ability to connect with Windows NT domain controllers. The output of the cifs testdc command is useful in the diagnosis of CIFS-related network problems.

There are two forms of the command:

cifs testdc [ domainname ]

is used when CIFS has been successfully started and is operational.

domainname tells the Filer which NT domain to search for domain controllers. If omitted, the Filer will search for domain controllers in the NT domain in which it is configured.

cifs testdc [ WINSsvrIPaddress ] domainname [ filername ]

is used when the CIFS subsystem is not running.

WINSsvrIPaddress is optionally given to have the Filer use WINS name resolution to locate domainname; otherwise, the Filer will use broadcast name resolution to attempt to find domain controllers. WINSsvrIPaddress is the IP address of a WINS server in the domain.

filername is the name of the Filer in the domain. If the name of the Filer is not given, then the Filer will manufacture a name to use for the search.

EXAMPLE

The following example was executed while the CIFS subsystem was started.
