1) is there a single SQL query for 2008 MSSQL to list the guest account status in all databases on a SQL Instance
2) is guest an actual account, i.e. a login, or is it more of a concept? If its an account, can you disable it so regardless of whether guest has access to a DB it wouldnt be able to be used to access the data?
3) does GUEST allow any user in your domain to access the database, or do you require a level of access on the instance to be able to access the databases via guest..
