When you perform a database validation with the DBConfig tool, you get an error. In SQL Management Studio, you notice a case database that is in Single-User status. The database has to be changed back to Multi-User.
The solution is to execute the following query where you replace Database_Name with the appropriate case database that is in Single User mode. ****Please speak with your database administrator before performing this task.
ALTER DATABASE Database_Name SET MULTI_USER;
