In this section, we will discuss Microsoft Access Database Engine cannot open or write to the File error rendered in two situations. So check that out.

Error 1# Run-time error ‘3051’: The Microsoft Jet database engine cannot open the file. It is already opened exclusively by another user, or you need permission to view its data

Problem:

When you start FRx or generate a report, you will catch into the following error message:

Run-time error ‘3051’: The Microsoft Jet database engine cannot open the file ‘\\server\share\FRx\Sysdata\FRxQue32.mdb’. It is already opened exclusively by another user, or you need permission to view its data.

Causes Of  Access Run-time Error ‘3051’:

Here are some well-known reasons that impart to the generation of such error codes:

• If the file is open on the machine or if it is on the network then someone still has it open.
• If the file is on the network the error can also be caused because of the security settings. So to fix it, you need to move the file locally on the server.
• If the file is local then chances are also that there are some permission issues.
• Chances are also that file that is showing the error message has the read-only attribute selected or maybe that user has insufficient permissions for the directory having the file.

Resolution To Fix “Microsoft Jet Database Engine Cannot Open The File It Is Already Opened Exclusively By Another”

Here are the fixes that you must try to resolve “The Microsoft Jet Database Engine Cannot Open The File It Is Already Opened Exclusively By Another” error:

Solution #1:

Before starting with the fixes make sure that file is not open anywhere else and you have copied it locally to the server. After then only try the following procedures:

Check out the file is saved locally on the server and is in the folder instead of being in the root folder.

If the file is in a folder, then go to the privilege section of that folder and make sure that users have complete access to read and write: “network service” and “asp”.

After allowing user access permission onto the folder if you still getting the same error. Then grant the user “Everyone” and test if this resolves the error.

Solution#2:

Use the window explorer, and browse for the error showing director. Make a right-click to the files listed in the error message and then its Properties option.

Make a check whether the Read-Only checkbox is selected in the Attribute section or not. If it is checked then, uncheck it and click Ok.

Move one level up to the parent of the current directory.

For instance: if you browsed to \\server\share\FRx\Sysdata\, moving up one level should display the \\server\share\FRx\directory.

Make right-click on directory having the listed file and then tap to the properties.

Make a hit on the Security tab and ensure that all FRx users have Read, Read & Execute, Write, and Modify permissions for the directory. If any user doesn’t have such permissions then add this permission and then tap to the OK option.  Repeat the action that caused the error as this prevents error to persist longer.

Error #2. Error 80004005 “The Microsoft Jet Database Engine cannot open the file ‘(unknown)’”

Symptoms of  Access Database Error 80004005:

The following error encounters when you use ActiveX Data Objects (ADO) or ODBC just to establish a connection to the Microsoft Access database.

Error message:

Microsoft OLE DB Provider for ODBC Drivers error ‘80004005’
[Microsoft][ODBC Microsoft Access 97 Driver] The Microsoft Jet database engine cannot open the file ‘(unknown)’. It is already opened exclusively by another user, or you need permission to view its data.

Screenshot:

Cause Of ODBC Drivers error ‘80004005’

Well, there can be several reasons regarding this specific error code:

• Chances are also that the account which Microsoft Internet Information Server (IIS) is using i.e IUSR does not have the correct Windows NT permissions for the folder that contains the file or a file-based database.
• File and data source name is either marked as Exclusive.
• Any other process or user has the access database opened.
• Sometimes the issue can also be occurred because of the delegation issue. so for this, you need to check the authentication method (Basic versus NTLM) if it is.

If the connection string uses the Universal Naming Convention (UNC), then try to use the Basic authentication or an absolute path such as C:\Mydata\Data.mdb. The problem also occurs when UNC points to a resource that is local to IIS computer.

• Another very common reason for such error is when you access a local Microsoft Access database which is linked to a table where the table is in an Access database on a network server.

Resolution To Fix “The Microsoft Jet Database Engine cannot open the file ‘(unknown)’” error

Try the following resolution steps to resolve Error 80004005 “The Microsoft Jet Database Engine cannot open the file ‘(unknown)’”.

Ensure the permission on the file and folder.  Make sure you have the ability to make /delete any temporary files. As, temporary files are been created in the same folder as the database, but files may be created in other folders like WINNT folder. 

If you choose the network path to the database (UNC or mapped drive), just check out the permission on the share, the file, and the folder.

Ensure that file and DSN (data source name) are not marked as Exclusive.

Other users are maybe of Microsoft Visual InterDev. So, close if all Visual InterDev projects having a data connection to the database.

Just use the System DSN which uses local drive letters. If important move the database to the local drive for testing.

Summary

A user reported an IIS error message when trying to access an Excel file in CODESOFT. “The Microsoft Access database engine cannot open or write to the file. It is already opened exclusively by another user, or you need permission to view and write its data.” This article explains the problem and provides a solution to resolve the issue.

Explanation

The likely reason for this error message is that the Windows database connection driver (Microsoft Access driver) is unable to access data from the destination file. In this case, CODESOFT (as part of TEKLYNX CENTRAL) tried to use the driver to access an Excel source file.

One or two situations may be triggering the error message:

1. The Excel file is stored under a different Windows user profile and the current user lacks permissions.
2. Another app in TEKLYNX CENTRAL is currently accessing the same file.

Solution

First, move the the source Excel file to a location that allows access by multiple users. An example folder is C:\Users\Public\Documents.

Next, you should make sure that the file is accessible. To do this, disconnect other users and applications. Or, make the file “read only”.

Visit this article for instructions on making an Excel file “read only” to avoid lockouts: ARTICLE

Issue found in Windows Server 2016

80004005 is a Jet Database Engine error that frequently arises in MS Access. This error substantially restricts the user from accessing the data file. Notably, the error doesn’t stem from a corrupted database; instead, it emerges as a result of several inconsistency issues. Predominantly, the most common trigger for the ‘80004005’ error is attempting to utilize a shared folder of VirtualBox. Therefore, as a recurrent issue, this error significantly disrupts the smooth progression of a database file. Now, let’s look into what the Microsoft Jet Database Engine 0x80004005 Error truly entails:

 Looks like:

•  You may receive a message like “Provider error ‘80004005’”

            OR

• “Unspecified error”

            OR

• “Database Connection (OLEDB) Exception. Unspecified error”

Causes Of Microsoft JET Database Engine 0x80004005 Error :

• MIIS (Microsoft Internet Information Server) account, comprises incorrect Windows NT permission.  In fact, this malfunction prevents the user from accessing the database file/folder.
• The name and file of data sources are noticeably Exclusive.
• In addition, MS Access database files are being accessed by multiple users and programs.
• The error ‘80004005’ sometimes occurs due to delegation defaults. So always, you must examine the authentication method before accessing the MS Access database. Moreover, the naming convention field is used to fix a permanent path with the help of a connection string.
• Sometimes, the error occurs due to the local database accessing the database linked to the global server.

How to fix Microsoft Jet Database Engine 0x80004005 Error?

Have a look over the multiple run-time error 80004005 messages, a user can receive while working on the database file.  Let’s take a look at what a particular message means and how to resolve them.

Message 1: The search key was not found in any record, Microsoft JET Database Engine 0x80004005 Error.

If users notice an unusual error, there must be an error regarding the Access database which has been corrupted. Hence, to solve this error, one might need to fix the database file. Follow the below-mentioned steps to repair the database file, if the database lies on the outlying server. 

• First, launch the Microsoft Access application on your program.
• After that, open the corrupted database and go to the Tools menu. Next, choose the Database Utilities option.
• Moving ahead, hit the Compact and Repair Database.
• Thereafter, fix the server via file transfer protocol.
• In the end, reload the database to the server.

Message 2: General error unable to open registry key, “Temporary (volatile) Jet DSN for process 0x6cc Thread 0x78c DBC 0x144cfc4 Jet”. Microsoft OLE DB Provider for ODBC Drivers.

• However, there is no such reason for the occurrence of the above error.  But, it can sometimes occur due to incorrect path details. 
• Finally, to repair the error, examine whether the given path details are correct or not.

Message3: [Microsoft][ODBC Microsoft Access 97 Driver]. The Jet database engine cannot open the file. You need permission to view this data or it is already opened by another user. Microsoft OLE DB provider for ODBC Drivers error “80004005”

• Due to accessing the local Access database table which is linked to an Access database table on the internet server. 
• Both file and data sources are distinguished as Exclusive.
• However, delegation issues can be the reason for this occurring message.  As a result, always choose a certified method (if available). Moreover, users can also try using the casual validated method, if a naming convention is used for a path like- C:\Mydata\ Data.mdb.it.

Message 4: Object or Database is Read-only. Microsoft OLE DB Provider for ODBC Drivers error “80004005”.

• The error typically occurs when someone initiates an update in the database.  Meanwhile, they are currently progressing with file insertion. Thus, it indicates that the user doesn’t have the authorization to edit the MS Access database.

• Reassure that you have uploaded the database ID to the Database folder at the same directory level as WWW.

Message 5: It may not be a database that your application recognizes, Microsoft JET Database Engine error “8000405”. The file may be corrupt or cannot Open Database.

This error message usually occurs in a basic server situation. However, it often occurs due to many clients using the network server at once. Let’s take a look at the solution to solve the error.

• Convert your database file to a SQL database file.
• Update your database to Acess 2000 version and then re-upload your database file. 

Message 6: Microsoft JET Database Engine error “80004005”, Table “tblTable” is exclusively locked by users on Machine “My Machine”.

• This error enables the user to view the database table or the table is already open in the Design view in your MS Access. 
• Exit the Access database and reopen it.

If the portable approach does not yield the desired results, opting for a third-party utility becomes the relevant option. In this case, consider the MS Access Database Recovery. This utility notably claims to restore BLOB data and offers dual modes of recovery. Furthermore, it seamlessly aligns with all versions of the Windows OS. Importantly, it notably extends strong support to MS Access versions 2013, 2016, and 2019, as well as earlier iterations. Additionally, this utility diligently ensures the efficient repair of diverse database contents, encompassing tables, reports, queries, indexes, and forms.

Conclusion

We conclude that resolving Error 80004005 is a challenging task overall. However, just because something appears difficult doesn’t mean it’s impossible. The above-mentioned solutions are sufficiently appropriate to address the recurring Microsoft Jet Database Engine 0x80004005 Error.
