When they try to log on, they receive following error message: The computer you are signing into is protected by an authentication firewall. The specified account is not allowed to authenticate to the computer. Corp.contoso.com users can log on successfully to client computers in the contoso.com domain by using their corp.contoso.com user account credentials.
