Yes, you can use nsradmin for this purpose. In general there are 2 steps to fulfill:

  -  create an appropriate infut text file

  -  'load' the file and create the resources  (nsradmin -i )

Use a standard editor to prepare the infput file. The input file should at leaste contain the required parameters:

  create type: nsr client; name: " "; comment: " "; ...

  - Verify/compare other parameters from any existing client

  - at the end of the line, do not add a semi-colon (;)

  - beware of Windows specifica like the double-backslash ("\\")

Example:

E:\>more infile.txt

create type: nsr client; name: "2008r2-nwserver.eval.local"; save set: "E:\\"

E:\>

E:\>nsradmin -i infile.txt

created resource id 37.0.8.7.0.0.0.0.191.239.189.87.195.214.70.35(1)

E:\>

BTW - you must not use the wizard:

  -  You can go add a new client via clients > new command

  -  You may also copy and existing client.

     Just do not forget to make the necessary changes before you hit OK. At least for ...

        -  the client name & comment

        -  save set

        -  delete the Client ID

        -  delete the Alias list
