I have an existing 2003 AD running on a Win 2003 PDC, which also acts as the data server, and several BDCs.
There is now the requirement for a dedicated PDC, running Win 2008 Std, to be installed immediately, but retaining the AD in 2003 format at the moment.
Please could you advise the best method to join a 2008 DC to the domain and how it should be set up to act as the PDC, with the existing 2003 servers as BDCs. The current PDC's hardware is unreliable, crashing regularly and need replacing.
Your help would be appreciated quite urgently.
