I have 200 remote Windows XP Pro machines that are not on a domain, workgroup only. I want to lock down the ability to change the windows time. I want to allow the local administrator account the ability to change the windows time, all 200 machines have the same local admin password. I know you can lock down the system time from the local security settings>user rights assignment. My question is, can you create a batch file that will do this? If so, give me an example on creating such a batch file.
