Hi Guys, I am attempting to Remove Exchange 2003 as we are Upgrading and Moving to Exchange 2007. We have a Exchange 2003 Server installed on a Windows 2003 R2 Enterprise Server. We also have a Windows Server 2008 R2 Enterpise DC which is jour Main DC in the Network. When I attempt to set the remove action i get the following error. Error is below: The compoent "Microsoft Exchange Messaging and Collaboration Services" cannot be assigned the action "Remove" because - Setup encountered an error while trying to contact the Windows Active Directory. The Error was: - Failed to contact the Schema Master Server for the Active Directory Forest. - You must be logged on to a Windows Domain instead of the Local Machine. The only option is OK.

Are you logged on as a domain member? Does the computer have a valid domain computer account?Ed Crowley MVP "There are seldom good technological solutions to behavioral problems."

Hi, From the error report, “ Failed to contact the Schema Master Server”. I suggest you runing this command. Dcdiag /test:knowsofroleholders /v If the Schema Master record has lost, you need to seizes the role.
