When we attempt to make a change to the structure of our gINT SQL database we get this message:
"The database is in use by [user] on computer [computer_name]. Changes are not allowed. You must have exclusive access to the database in order to change the schema."
The user named in the message does not even have gINT open.
Open the SQL database in Microsoft SQL Server Management Studio. Open the WH_Lock table to view the data. There will be a row with this user's name. Delete this row.
