Vince, yes it's possible :o)
You can do the updates and reboots too, all over the LAN/WAN/or internet if you desire. Since theres alot of assumptions here, to better answer your question and to assist you, I recommend learning Cscript or WSH (Wscript) - the Windows server operating system has many system and local environment variables to utilize look at
http://www.microsoft.com/technet/scriptcenter/default.mspx to begin. Also, when you've gotten your feet wet,
http://www.microsoft.com/technet/scriptcenter/createit.mspx. Both are good resources for script administration. Another helpful item(s) you'll need to be familiar with to be a good Windows Administrator is to click Start/Help and Support Center, and search for "Command-line reference A-Z" - without the quotes. Many of the enviroment variables can be manipulated with the commands that will appear. Best of luck. A
