I just correct the script gived from Gilles, to add the NS server name (to change yours).
Notice: not tested yet this one. Notice also: best to install a data partition, if available, instead a system partition !! :)
You should put, the msi file (from <\\SMPserver\NSCap\bin\Win32\X86\NS Client Installation>) and this script into NETLOGON domain folder, and add a GPO to run it at machine startup.
I would like to test if the system is a server with a data partition, or a workstation a single C drive, to deploy different path according the system type.
