PerformancePoint 2007, Planning server configuration error

I'm trying to configure the planning server for performancepoint 2007. I have the database setup on a separate machine on the same network. Everything seems to validate correctly but on the last step of the configu开发者_运维知识库ration screen, when I click "configure", I get this error:

Configuration failed.

Error 1:  Windows NT user or group 'DEV-WEB\Administrator' not found. Check the name again.

Does anyone know what this error is?

Found documentation online saying that the 2 servers need to be on the same domain or you have to use a trusted domain so the sql server can access the admin console on the other server.
