I have a clue... the login being referenced is a service account used by the application for connection purposes. The login id in question does not exist in the production database, a different name is used for security purposes. The DB refresh script has been used for a number of years but, recently changed and that's where the fun occurred. The grantdbaccess was commented out for some reason but, the addrolemember was still assigning security rights to the database. Therefore, the login had security rights on the database but, didn't have permission to access the database.
THAT WAS FUN!
Thank you for hanging in there with me - in the end it was still a learning exercise, which is always a good thing. :-)
