1) When I come to install Windows Server 2012 Standard how many users can connect to it at any one time? 2) Say I have the website domain name mydomain . co . uk, (spaces added due to little post count) when I come to install Windows Server 2012 Standard it asks me to enter the root domain name. Am I OK to enter internal.mydomain.co.uk? I don't have this server running as an email server, and it will never run as one either (it's just going to be a file server with Active Directory running), so will this cause problems or is it just for internal use and it won't affect the domain name I have already of www . mydomain. co. uk. Just a bit confused on the root domain bit, as I don’t want the outside world to "connect" to it. 3) I've been experimenting with groups and users to set up folders and read/rights to. However, is it possible to "hide" a folder from a group/user? After some tests I've managed to add a group called "IT" added some users and created a folder called "Plans" then added another group called "Reception" added some users and I don’t want the "Reception" group to see this folder "Plans". At the moment they can see the folder but when they double click on it, it shows you don't have access rights to this folder. Is it possible to not show it at all? If not I'll leave it with the error message showing. 4) I will have 2 HDD's (1 for the Operating System and 1 for the data storage) I have already got a backup system in place but if the Operating System HDD goes down, what files/folders should I backup relating to the Operating System and where are the settings held of all the users/groups/GPO's/Active Directory settings etc so that if I had to rebuild the server I can just install the Operating System and import all of these settings in. Is this possible? Many thanks for the help!!
