Unattended SQL install on a remote machine My product installation does an unattended install of SQL Server (SQL Server Express by default). I use command line arguments rather than a configuration file, so I'm quite familiar with this process.

This unattended install occurs on the same machine that my install media is running on. However I need to look at installing the SQL Server instance on a separate machine to what the install media is running on. The target machine will be on the same network. 

Is it possible to do this unattended? If so, is it simply extra command line arguments or is it a different process (i.e. a PowerShell script)?
To perform unattended install to a remote machine you should consider providing a separate installation option that allows just the database engine to be installed on a machine, and forget about doing it remotely.  Remote installation will be very difficult to troubleshoot and is not transparent for the installing individual.

Having said that you could look at using SysInternals PSexec.exe to remotely spawn the unattended install.
