Hi,<br />
<br />
Just wanted to check if the Windows 2003 Environment is running in Mixed mode or Native mode. IF 2003 domain is running in mixed mode you can raise the forest functional level to Native mode as long as you do not have any DC's with Windows 2000 OS.<br />
<br />
The following article gives you a clear picture of Domain/Forest Functional levels and the impact of introducing the Windows 2008 Server in Windows 2003 environment.<br />
<br />

Hi and thanks again - your answers explain everything clearly as usual. I have no NT4 &nbsp;DCs - only 2003 DCs and I will progress this change with a better understanding.

HI<br />
<br />
I am trying to add a new 2008 server as a dc on a 2003 network and have successfully run adprep/forestprep. Now I need to run domain prep but it is telling me to switch the domain to native mode.<br />
<br />
Firstly, why? and secondly will there be any risks/adverse effects anything to look out for etc etc?<br />
<br />
I also have an exchange 2003 server and a sql 2000 member server - there are currently 2 other DC's on the network which are primary and secondary dns machines.<br />
<br />
thanks

promoting a 2008 machine to a DC on an XP/2003 server network - switch to native mode to run domain prep

Windows Server 2003 was based on Windows XP and was released in four editions: Web, Standard, Enterprise and Datacenter. It also had derivative versions for clusters, storage and Microsoft’s Small Business Server. Important upgrades included integrating Internet Information Services (IIS), improvements to Active Directory (AD) and Group Policy (GP), and the migration to Automated System Recovery (ASR).
