I have installed a windows 2012r2 server to my existing domain and promoted it to DC. Since then a number of win 7 clients are not getting all the correct settings the main one being is that they do not get mapped drives. This is done through a logon scripted on the user in AD. The problem is not there if the clients talked to an existing server 2003 or 2008r2. I know this as when I switch off the 2012r2 server the problem goes away.
I have read through other forums that there is a delay on the GPO applying but nothing is mentioned about this fault. Please could you enlighten me in why this is the case and what I need to do to resolve the fault?
