You are a local admin on the server right to which you are installing exchange right?

Yes.

Is auditing turned on? What have you got in the security log? Also anything more detailed in the setup log?

I check Default domain controller security settings -> Local Policies -> Audit Policy. My security log, dosent log much. I don't know why? Regards Kenneth Dalbjerg

Just for testing. I have changed the logon settings for Microsoft Exchange Transport service to administrators. And now the services will startup just fine. But i know that the service need to be running as network service, so I have changed it back. So it must be a problem with a security somewhere. Do you know what kind of security / permission Network Service must have to start this services?

Are you installing exchange on a domain controller?

Yes, on a Microsoft Windows 2003 R2 x64bit. I know that, that is not recommended. But i have done this on 3 other server, not in this domain or forest, but in a other.
