Service 'MSExchangeTransport' failed to start
Hi, I have windows 2003 SP1 with DNS and AD configured. When I try to install Exchange 2007 Beta 2, I get the following error when installing HUB transport role. Service 'MSExchangeTransport' failed to start. Check eventlogs for possible reasons for the service start failure. [When I had first tried to install, it had successfully passed this stage but failed in installing Client Role. So I uninstalled Exchange, but it did not clean up AD. So I reinstalled DNS and AD. Now it continually fails at installing HUB transport role] Looking at the event logs have the following: 1. Process ExSetupUI.exe (PID=2896). An RPC request to the Microsoft Exchange Active Directory Topology Service failed with error 1753 (Error 6d9 from HrGetServersForRole). Please make sure the service is running. 2. Unable to register the service principal name SmtpSvc: The logon attempt failed For more information, see Help and Support Center at http://go.microsoft.com/fwlink/events.asp. 3. Failed to obtain an initial instance of transport server configuration during initialization. The service will be stopped.

I am getting all exact same errors for the second time. Last time I rebuilt AD , not doing that again. Just modifying this post.........I changed the username of the service to domain admin a/c and it started.

That service is supposed to run under the NetworkService account, and not under a user account, let alone a domain administrator account. See http://www.microsoft.com/technet/prodtechnol/exchange/e2k7help/5edce346-7f12-4262-a128-03d7a7b04c63.mspxfor more information.

thanks Scott, I know that but it was the only work around rather than rebuilding AD, just for testing anyways ! Hopefully GA code won't have the issue :o)

This may be of use:If you are using an existing mail system (non-Microsoft) make sure you disable these first or the Transport service will fail. For example, if you use Matrix Control Panel with Matrix Mail, stop in the panel then stop the service. Transport will now start!

I had installed Exchange 2007 Beta on Windows 2003 SP 1 before but on Windows 2003 SP 2 R2 I am having that Hub Transport Role with MSExchange Transport service failed to load problem. Has anyone resolved that?

I was expeiencing same issue and it got resolved by putting network service account as Log On tab for the Microsoft Exchange Transport Service. regards, Invincible
