    Sounds like your connection string is not correct or the listener configuration is wrong.

    It could be the case that the DB is down & needs to be started.
    You can lead some folks to knowledge, but you can not make them think.
    The average person thinks he's above average!
    For most folks, they don't know, what they don't know.
    Good judgement comes from experience. Experience comes from bad judgement.
