I have an access database that is on a network drive that multiple users can access. The database corrupted this morning and I am in the process of trying to fix it. The problem I am having is when I attempt to rename the database it says it is currently in use by someone. There is no .ldb file associated with this file so at this point and am dead in the water because I can’t rename it, compact it or anything.

Does anyone have any suggestions?

Thanks

unlock access database

It’s pretty obvious that you have lost or forgotten your MS Access password and looking for some perfect solution to Access password recovery.  But before the recovery it’s important to learn how Access stores its password.

Technically, ms access database password stores in the following regular pattern.

1). Jet 3 –

In this mode, MS Access database password gets saved in the header of the MDB file and format remains as a plain text.

2) Jet 4 –

In this, the password is encrypted with basic XOR pattern algorithm depending on data and times of file production. Further it saves data in MDB file header.

3) Jet 3 & 4 –

Password is further encrypted with a XOR pattern affecting the MDB file.

4) ACCBD Files –

The password is not encrypted as plain text in the header file at all.  Instead new # value is allocated to authenticate the user’s password validation.  Hash produced by the tool is a combination of tow RC4 and SHA-1 algorithms.

In order to encrypt your access database if you have chosen the pattern then it’s quiet difficult to crack. Especially, applies with the ACCDB files but MDB file are still possible to be recovered.
