Code is below and any help for this novice is greatly appreciated.
Is there perhaps a recordset that gets opened on startup and is still open? Try opening the db while holding down the Shift key and then trying to split.
Is there perhaps a recordset that gets opened on startup and is still open? Try opening the db while holding down the Shift key and then trying to split. It's a fairly basic function; it deletes all rows, and then resets the auto-increment index by changing the data-type of the ID column to However, I'm running in to a problem; on occasion, when a user presses a button that calls the function, I'm halted by an error - The database engine could not lock table 'Active Directory' because it is already in use by another person or process. This error does not occur every time, but once it appears, I have to close Access to make it go away. The error occurs on this line -

Contents While working on tables in MS Access database, you may experience the error 3211, with the message “The database engine could not lock table”. It can occur if the database is in use by another user. Sometimes, the error occurs if you have opened the table of the database in the design view. In addition, there could be many other causes for the runtime error 3211. What causes the error 3211 in Access?Following are some possible reasons for the runtime error 3211 in MS Access:
Methods to Fix the Runtime Error 3211 in MS AccessYou can get the runtime error 3211 in MS Access if multiple objects of the database are opened. So, check and close all the objects before working on the tables. If this is not the case, then try the below methods to fix the error: Method 1: Delete Microsoft Access Lock Information FilesMS Access uses LDB (lock information) file to manage the record locking when multiple users use the same database at a time. This file is created when a user access or open a database and gets automatically deleted when the user closes the database. Sometimes, it fails to get deleted automatically, resulting in errors, such as the error 3211. In this case, you can delete the lock (LDB) file manually using the below steps:
Once you deleted the file, try to open the database and check if the issue is fixed or not. Method 2: Remove Missing ReferencesThe runtime error 3211 can occur if the query you are using to lock the table in the code is a reference to a missing object library. It usually occurs when you use Recordset2.LockEdits property (DAO) or TableDef.lockEdits property. To fix the issue, you can check and remove the missing references from the code. Here are the steps:
Method 3: Check the Primary KeyYou can also get the error 3211 in MS Access if the relationship between the tables is not correctly defined. To fix this, you can check and set the primary key. Follow these steps:
Method 4: Check and Change the Database PermissionsYou may encounter the runtime error 3211 if you do not have the permission to lock the tables in the database. You can check and change the permissions of the database. Here are the steps:
Method 5: Repair your DatabaseCorruption is also one of the reasons for the error 3211 – The database engine could not lock table. To repair the corrupted database, you can use the Compact and Repair tool in MS Access. To use the tool, follow these steps:
