Hi Subbu There are a number of options depending on what client OS and what NBU version. For Windows, and any NBU version, run the standard windows installer from a cenral server and choose client installation - at one point you can choose to perform a remote installation and if you progress you are given the option to add in multiple servers (you will need to provide remote admin credentials for the install). This will work for upgrades and new installs.
For Unix/Linux etc. and NBU version 8.1.2 or better - you can use VXupdate to run a push install from one of your existing NBU servers (the caveat is that the client must already be running NBU already). this will not work for new installs to any *nix platform.

Please tell us more about your environment - Which NBU version are you currently on? You have tagged W2008 as OS - is that the OS on your master server? Which OS's on the clients that you want to install? Are all of them new installs or upgrades?
