MS Access forms grants an easy way to modify and insert records into your databases and a subform is a form within a form which is generally used when you want to show data from multiple tables i.e. in one to many relationships of the tables. But sometimes when you open a form in the database which has a control on it that references a subform control and when try to open a second instance of the database you may receive the following error message:

The database has been placed in a state by user ‘username’ on machine ‘machinename’ that prevents it from being opened or locked.

The reason for the same could be:

A form contains a subform and the control on the main form references one of the controls in the subform and the database is opened in a single instance of the database.
The database is corrupted.

To workaround the problem Microsoft has suggested to obtain Microsoft Office 2000 Service Release 1/1a (SR-1/SR-1a). This service pack can solve the problem of the user unless and until the database is corrupted. However if this does not solve the mentioned error then there is none other way to have some Access repair software.
