$computers="computer1","computer2" $path="\\server1\sharefolder\TestInstall.msi" $computers | where{test-connection $_ -quiet -count 1} | ForEach-Object{ copy-item $path "\\$_\c$\temp" } Invoke-Command { dir c:\temp\TestInstall.
A sample project will be set up in Visual Studio for writing psake script,
