Hi, Form your picture, ADUC on Windows server 2003 displays correctly. However, Windows server 2008 seems to be abnormal. I built the similar environment according to your description. The result is expected. To further assist on this, could you please inform me if you use RTM version of Windows Server 2008? If so, which version are you using? Please locate: [HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\ComponentBased Servicing\Version] registry key. There is a subkey which contains the Windows build information. What is the registry value? Is it 6.0.6001.18000? In addition, if you choose 'connect' on Windows server 2008 side to connect Windows server 2003 DC, can you successfully connect it?

Hi.Thankyou for your reply.Yes that registry value is correct.Yes i can connect to 2003 from 2008, and the other way around./Michael

Okay i just got off the phone with MS, apparently that is no problem. kinda strange since both servers in my test domain shows as being online, but i have transfered fsmo roles, and everything seems to be working fine. thank you for your time./Michael
