Hi Guys, The Hub Transport and Client Access Roles install Fine. But when i get to the Mailbox Role it stuck on 50% and the following information is logged every 2 secounds in the Application Event Log and the Topology Version increments by 1 with each event logged. Event Type:InformationEvent Source:MSExchangeADAccessEvent Category:Topology Event ID:2150Date:02/08/2006Time:11:39:52User:N/AComputer:KINGS3Description:Process exsetupui.exe (PID=4108). The following Active Directory servers are going to be used in connection pools of this process: Domain Controllers: kings3.kingsbus.localGlobal Catalogs: kings.kingsbus.localConfiguration Domain Controller: kings3.kingsbus.local. Topology Version 3409, Topology provider: DirectoryServicesTopologyProvider. For more information, click http://www.microsoft.com/contentredirect.asp. Any Ideas? Thanks in advance.

I had to stop one of the services, I think it was the transport service, but it could be another :)
