Disturbance GPO is applied to OU of servers as well, when not needed
Recently I followed guide to make deployment of office 2010 through start-up scripts, as per guide I applied it to computers so I've two OU's one for laptops and one for desktops. I applied it to both and the result was good, I tested on 3/4 machines as soon as i Joined to our windows domain a copy of office 2010 was installed on them.
But today I found this that due to some maintenance I restarted one of our Win 2008 R2 server which is member of our windows domain and the OU it lies , I did not link the GPO of office 2010 deployment to it, but strange after I restarted this server after few seconds I found office 2010 installed on it as well, this is something I really don't want. When I only linked the GPO to desktop and laptops OU how this is happening.
Please assist for this and see attached screen shot, if more details needed please let me know.
