After installing and joining a new SBS 2003 server to my current Win2K domain, I am unable to continue the setup to install Exchange etc.. When I click on the icon and get the "Setup requirements" window saying: "You must be a member of the Domain Admins, Schema Admins, and Enterprise Admins groups."
The problem is that I am using the main administrator account and it IS a member of all those groups. I have rebooted the main server and everything appears to be set up correctly.
What am I missing?
