When I run the pre deployment analyzer it tells me my domain functional level is not Windows 2003. Yet when I go into Active directory Domains and Trusts and right click on the domain, hit the raise domain functional level option it tells me my domain is at it's highest level "Windows 2003". Has anyone had a similar problem? Thanks

Are you sure that the error doesn't report on the forest functional level? Do you have more than one domain in your forest?Ed Crowley MVP "There are seldom good technological solutions to behavioral problems."
