Last week I installed sql server express 2008 by mistake instead of the Standard version. I went into the control panel of the server and uninstalled everything that was there. This week I've installed sql server 2008 R2 and when I launch the Management Studio it has 2 instances of SQLEXPRESS and still remembers one of the user accounts that logged in to that prior instance. No matter which one I pick it won't allow me to log in and the error states:
'Cannot connect to server\SQLEXPRESS A network-related or instance-specific error occurred while establishing...'
If I go to add/remove to remove the instance, it's not there. The only one that's there is MSSQLSERVER which should be in the list? Is this correct for Standard?
Is there anyway to fix this mess up?
