Okay - I'm an idiot.
I just installed MSSQL 2012 developer edition on my Windows 8 Pro machine using all the default settings. I login using windows authentication and changed my default database to point to a project database I'm working on.
When I dropped my project database, rather than just pointing me at master when they can't find my default db, SSMS and SQLCMD just gag and kick me out.
I chose windows mode security during installation and have no recollection of every specifying an sa password.
I currently have no way to login to MSSQL.
Any suggestions would be GREATLY appreciated!
