nblookup /?

Verifies NETBIOS name registrations on specified WINS server

Command line mode usage:  nblookup [-options] NetBIOS_Name_to_Query
Interactive mode usage:   nblookup [-options]
Query List mode usage:    nblookup -ql input_file [-qr report_file]

Command line mode options explained:

       – maximum 15 alphanumeric characters
       – no dots or extraneous characters

    /s used to specify the WINS server to query
       – can be an IP address or name
       – default value is local system’s WINS server

    /x used to specify NetBIOS suffix to query
       – must be a valid NETBIOS suffix
       – must be in hexadecimal format
       – examples:  00, 20, 1B, 1C
       – default value is 20 (File Server Service)

    /suffix_help displays list of common NetBIOS suffixes
       – cannot be used with any other option

    /t used to specify timeout period for query
       – valid range: 1 – 20 seconds
       – example: /t 5

    /r used to specify number of queries/retries

       – by default queries use recursion

    /i used to specify NetBIOS Scope ID
       – ID is appended to NetBIOS Name for query
       – ID is case sensitive
       – useful only on networks that use scope IDs
       – example: /i MyScopeId

    Press Ctrl-c to terminate prematurely


    This example queries WINS server for
    the File Server Service registered by computer1

       nblookup /s computer1

    This example queries the WINS server called WINS1 for the
    domain controllers registered in the domain called DOMAIN1

       nblookup /s WINS1 /x 1C DOMAIN1

For help with Interactive mode options:
    – run nblookup.exe
    – then type ‘help’ <enter>

Query List mode options explained:

    /ql used to run in ‘Query list’ mode
       – sends WINS queries specified in a text input file
       – must specify the path and name of the input file
       – create a sample input file by running:
         nblookup.exe /ql autocreate
       – cannot be used Command line mode options

    /qr used only with /ql option
       – specifies name of report file to create when /ql used
       – must specify the path and name of the report file
       – .htm extension automatically appended to specified name
       – default report file: nblookup.htm
       – cannot be used Command line mode options

    /ql autocreate
       – used to create a sample input file called in-nblookup.txt

    /y used to overwrite existing report file without prompting
       – cannot be used Command line mode options
       – useful in scripts


    This example builds a sample input file called in-nblookup.txt

       nblookup /ql autocreate

    This example runs queries specified in the input file called
    in-nblookup.txt and creates a report called myreport.htm

       nblookup /ql in-nblookup.txt /qr myreport
