I need some help trying to add another instance to SQL server express so we can run a new application. I have no clue what I am doing. There is already an instance GRFP2\SQLEXPRESS. Can I add the new database to that or do I need to add another? When I run the setup for the app, it asks for the sql server info. I put in the instance above, but it will not take the admin login and password. I have tried everything including DOMAIN\Administrator. It keeps giving me the error saying that the connection cannot be established. I'm have a service ticket open with the vendor and I am waiting for them to call but this is driving me crazy. I don't think they'll be much help since it's a password issue. Any help? Sorry for the rant, I'll try and explain better if you need me to.
