I have one desktop PC running windows 7 + powershell.
I have a mixture of windows 2003 and 2008 servers.
I would like to write a script which logs into each one and report back the uptime of each and then export to csv file.
My question is if it is mandatory to have powershell installed on the windows 2003 or windows 2008 servers? What technology will be used by my windows 7 machine to communicate with the servers?
