What Causes Operating System Error 5 in SQL Server?

The major reason for the occurrence of this error is when SQL has inadequate permissions and cannot access files. Other scenarios when this access denied error usually arises are:

• Incorrect backup file path usage during backup restoration.
• Insufficient read/write permissions for the backup file.
• Damaged, corrupted, incompatible, or inaccessible backup files.
• Does not have administrator privileges or permissions for SSMS.

It is necessary to fix this error to keep data intact and operate the SQL server smoothly. If it is left unresolved, then you may have to face performance degradation and data loss issues.

Methods to Fix SQL Server Error 5 Access Denied Error

Like the Microsoft SQL Server Error 18456, this error 5 also stops users from working efficiently. There are a few manual steps that you can follow to resolve this error. Alternatively, there is a professional tool that can handle this error and recover your backup file. Explore the steps below and execute them appropriately to achieve successful results. 

Resolve SQL Server Error Code 5 Manually

As stated above, the error majorly occurs due to the issues with backup files. What you can do is check that the correct backup file is selected. Also, sometimes, only changing the filename or location does the work. If this doesn’t help, then follow the steps given below:

1. First, ensure the backup file and folder path are correct and accessible from the SQL Server.
2. Next, verify and grant security permissions:

• Browse the folder where your backup file is saved, right-click it, and select Properties.
• Further, check that the user trying to fix the backup file has relevant access permissions.
• If not, click on Edit >> Add under the Security permissions.
• Use object names and check names for verification.
• Furthermore, click Advance to search for the name of the user and continue.
• Later, adjust the needed settings and configurations.
• In the end, ensure you grant the Modify permission. Once done, hit OK.

1. Now, SQL Server Error 5 Access Denied may also occur if SSMS is not run with administrator privileges. So, simply go to Windows Search and type SSMS. Right-click it and press Run as Administrator.

• Check and Grant Database Instance Permissions:

The service account for the SQL Server must have the permissions to read, write, attach, and detach the database. If not, this may result in Error 5 in the SQL DB.

• To check for the needed permissions, run the given command:

SELECT nameof service, account_service

FROM sys.dm_server_services;

• Once you get the service name and account details, grant the required permissions.
• Additionally, add the Administrators group to security permissions. (It is needed for data directories saved in SSMS.)

1. Repair your database with the DBCC CHECKDB (REPAIR_ALLOW_DATA_LOSS) command. Also, repair the backup files.

Shortfalls of the Manual Method

Though the above-given free ways may help you to resolve the operating system error 5 to an extent. It has some cons mentioned here:

• Administrator privileges are needed to modify permissions for service accounts and folders.
• It is a time-consuming process and is not suitable for issues with complex permissions.
