I have an external trust created from my 2000 domain to a separate and unrelated 2003 domain. I can successfully grant 2003 users access to resources on my 2000 domain.
I cannot grant 2000 domain users access to resources on the 2003 domain. When I try to add a 2000 domain user to the permissions list of a folder on the 2003 server, I can select the 200 domain but it will never find the user I specify either just username or firstname.lastname@example.org (UPN) format?
Looking for some verification of my tust settings on the 2003 server.
