So... I have for test purposes setup a VM on oracle virtualbox for Windows Server 2008, added the role for AD DS, with a domain 'wigston.leicester'. I have then installed Windows 7 Enterprise on a separate VM within the same network and tried to connect to the domain but am getting the attached error. any ideas? I am new to all this server setting up business from scratch, I am fine working with servers when they are running by adding new users and domain the account administration, but this is all new to me... I have an interview tomorrow and think I may be tested on a lot of this so could be handy to get my head around as much as possible today and tonight.
