Having recently upgraded from an "inherited" W2K3 server enviroment to a W2K8 R2 system (forest and domain are both at this level), I'm reviewing the ADUC accounts and had some basic questions.
Properties>Account>User Logon Name
Some users are listed: user1, user2
While others are listed: user3@domain.local,user4@domain.local
My question is what are the pitfalls of having users not listed with the @domain.local in AD?
I plan to go in and select @domain.local from the drop down on the one's that don't have it selected, but wondering too will that have any adverse effect on existing settings/permissions for that user?
