I wonder whether its alrite if I created a group in built-in group in active directory user and computer?. This is because I created a policy to redirect files from user to their home directory for backup purposes.

Not sure I understand you, but policies don't work on groups. You need to make an Organizational Unit. Peter (Alert me if you want a reply)

thanks for your advise. Well, I was saying that whether it is ok if I create a new security group in Active Directory Users and Computers. Ok...be more specific, under Active Directory Users and Computers ---- Domain Name (eg. test.com) ---> Builtin Folder. In this Folder, can I create a custom security by me?. Do you think its appropriate to put it here?.

Hi, It would not be my choice - just makes it harder to find later on, bothfor you and someone else, but if you have particular reasons for doing it, I don't see any real harm. Peter (Alert me if you want a reply)
