When SQL Server is installed
by default, the guest user is disabled for security reasons.
There are many ways to get
guest user status:
Using SQL Server Management
Studio
You can expand the database
node >> Security >> Users. If you see the RED arrow pointing
downward, it means that the guest user is disabled.
Using sys.sysusers
If you notice
column dbaccess as
1, it means that the guest user is enabled and has access to the
database.
SELECT name, hasdbaccess
FROM sys.sysusers
WHERE name = 'guest'
Using sys.database_principals and
sys.server_permissions
SELECT name, permission_name, state_desc
FROM sys.database_principals dp
INNER JOIN sys.server_permissions
sp
ON dp.principal_id = sp.grantee_principal_id
WHERE name = 'guest' AND
permission_name = 'CONNECT'
Using sp_helprotect
the following stored procedure will give you all
the permissions associated with the user.
sp_helprotect @username = 'guest'
Disable Guest
Account
REVOKE CONNECT FROM guest
