Hello, you have to prepare your forest and domain for the add of the 2008 server. All steps are mentioned in this Microsoft guide: http://technet.microsoft.com/en-us/library/cc731188(WS.10).aspx One done, run dcpromo and promote the additional DC. Note that it is recommended to have at least two DC/DNS/GC servers per domain. This posting is provided "AS IS" with no warranties or guarantees , and confers no rights.
