I am replacing a Windows 2000 Small business server with a Windows 2003 Small business server and I am having trouble creating a trust relationship between the two so I can migrate AD and Exchange to the new SBS 2003 server, the new 2003 server has a different domain name. I get an error message that I cannot create the trust relationship on Small Business Server, does anyone have any idea why this is happening? Why would the option be there is it cannot do trust relationships. Is there any other way I can migrate the Active Directory and Exhange to the new server without creating the trust relationships if they are not possible? How would you replace the old server with the new server? Any help is greatly appreciated.
