This article explains solutions to fix SQL server restore database failed access denied. Due to this problem, a normal error can occur in MS SQL Server. So, we’ll discuss different techniques to solve this problem.

When users try to restore the SQL Server database from the backup, it is very regular to receive an error message that reads as follows:

Restored failed for Server ‘xxx’ (Microsoft.SqlServer.SmoExtended)
Additional Information: System.Data.SqlClient.SqlError: Exclusive access could not be obtained because the database is in use.
Reason for SQL Server Restore Database Failed Access Denied

The main reasons that could interfere with restoring the process of the SQL Server are:

Opening multiple windows ‌while using the SQL Server Management Studio can obstruct the SQL Server database restoring process.
Sometimes, network connectivity errors can prevent a successful SQL Server database restoration process.
Using the same SQL database you are trying to restore can also be the reason for a failed process.
A damaged or corrupted SQL Server file can lead to restore failure.
Multiple users have connected to the main SQL Server database.
While reconnecting to the process, the user database file is synchronized.

Manually Fix SQL Database Restore Failed

When attempting to restore a SQL Server database, ensure there are no active connections. If someone is accessing the database, the restore operation will fail. To remedy the issue, you must disconnect the active users. You can do so using any of the following methods:

Method 1 Close all the existing connections to the SQL Server Database

To disconnect the existing connection to the MS SQL database, use these steps:

First, open SQL Server Management Studio (SSMS) and connect to the SQL database.
After that, the Object Explorer window will show on the left side of the SSMS.
In Object Explorer, right-click the database, then choose Restore database.
In the Restore Database option, do the following
Choose one of the SQL databases to restore
In the left panel, click Options
On the Options page, tick the checkbox written as, “close existing connections to destination database”.
Once the SQL connection is closed, start the restored operation.

Method 2 Change the SQL database from multiple-user mode to single-user mode

Changing the multiple-user mode to a single-user mode can disconnect all the connected users. However, this method can only be used when you want to disconnect all the SQL users without notifying them.

Open SQL Server Management Studio (SSMS), and connect database.
In the Object Explorer window, choose the new Query and run the T-SQL command.

USE master;
GO
ALTER DATABASE DB_NAME
SET SINGLE_USER
WITH ROLLBACK IMMEDIATE;
GO
Run above code will change the SQL database to single mode.

Method 3 Restart the MS SQL Services

Search the SQL Server Configuration Manager as follows:

SQL Server 2019 C:\Windows\SysWOW64\SQLServerManager15.msc

SQL Server 2017 C:\Windows\SysWOW64\SQLServerManager14.msc

SQL Server 2016 C:\Windows\SysWOW64\SQLServerManager13.msc

SQL Server 2014 C:\Windows\SysWOW64\SQLServerManager12.msc

SQL Server 2012 C:\Windows\SysWOW64\SQLServerManager11.msc

On the left side of the MS SQL Server Configuration Manager option, click SQL Server Services. Now, on the right side click on SQL Services, and stop and start it.
Tab the OK button to return to the SQL Server Configuration Manager.

Cons of Manual Method

The process takes a lot of time to complete and does not give results in a fast way.
Loss of information is very high in manual methods.
Technical expertise in SQL queries is essential to complete the process.
