Lansweeper data, reports and settings are stored in a database. Your database is hosted in either the Microsoft SQL Compact, Microsoft SQL LocalDB or Microsoft SQL Server database server. If you install Lansweeper under SQL LocalDB or SQL Server, the installer automatically creates a SQL user called If you install Lansweeper under SQL Server, by performing an Advanced Install, the installer automatically.... This user is used by the Lansweeper scanning service and web console to connect to the database.
If lansweeperuser gets corrupted, or has its password changed without an accompanying update of the Lansweeper configuration files, the service and console will no longer be able to connect to the database and you may see errors like the one below. The error below indicates that, even though Lansweeper is able to find the SQL instance hosting the lansweeperdb database, it is unable to access the database with the lansweeperuser account. It's important to note that this does not point to database corruption or an issue with the database itself. It simply indicates that the database cannot be accessed to read or write information. To resolve this issue, lansweeperuser needs to be reset.
To reset lansweeperuser and have the service and console successfully connect to the database again, do the following:
- Stop the Lansweeper Server service in Windows Services
- Stop your web server service in Windows Services. Your web server service is either IIS Express or World Wide Web Publishing Service (IIS).
- Log into SQL Server Management Studio. If SQL Server Management Studio isn't installed on your Lansweeper server, we recommend downloading it online.If your database is hosted in SQL LocalDB, the SQL instance name you need to submit in Management Studio is (localdb)\.\LSInstance and you can log in with the Windows user that initially installed Lansweeper. If your database is hosted in SQL Server, you would have configured your SQL instance name and password when you installed SQL Server.
- If your database server is SQL Server, make sure your SQL instance is configured for mixed (Windows and SQL) authentication. (If your database server is SQL LocalDB, your SQL instance should already be configured for mixed authentication by default.)- Right-click your SQL instance name in SQL Server Management Studio.- Select the Properties menu item.- Select the Security tab in the resulting popup.- Tick SQL Server and Windows Authentication mode- Right-click your SQL instance name and select Restart.
- Execute the script below in SQL Server Management Studio to reset the lansweeperuser SQL user used by the Lansweeper service and web console to connect to the database. Replace what's marked in bold with the password you'd like to use for the lansweeperuser database user, leaving the single quotes in the script./* Makes sure there are no objects in the lansweeperuser schema, so the lansweeperuser SQL user can be reset */
DECLARE c_ALTSCHEMA CURSOR FOR
SELECT 'ALTER SCHEMA dbo TRANSFER lansweeperuser.'+name +';'
WHERE SCHEMA_NAME(SCHEMA_ID) = 'lansweeperuser'
DECLARE @SQLStmt NVARCHAR(200)
FETCH NEXT FROM c_ALTSCHEMA INTO @SQLStmt
WHILE @@FETCH_STATUS = 0
FETCH NEXT FROM c_ALTSCHEMA INTO @SQLStmt
/* Resets the lansweeperuser SQL user */
DROP SCHEMA lansweeperuser
DROP USER lansweeperuser
EXECUTE sp_droplogin lansweeperuser
EXEC sp_addlogin 'lansweeperuser', 'lansweeperuserpassword', 'lansweeperdb', [English]
EXEC sp_grantdbaccess 'lansweeperuser', 'lansweeperuser'
EXEC sp_addrolemember [db_owner], 'lansweeperuser'
/* Optional step to grant lansweeperuser dbcreator rights, which are required for Lansweeper Enterprise */
ALTER SERVER ROLE [dbcreator] ADD MEMBER [lansweeperuser]
- Run the following tool, found on the servers hosting your Lansweeper Server service and web console:Program Files (x86)\Lansweeper\Tools\ConfigEditor.exe
- Click through any warnings the tool may be giving you about your password being incorrect.
- Select the Password field and hit the Edit button.
- Submit the same password you previously used in the database script and hit the Save button.
- If the ConfigEditor tool has multiple tabs due to your server hosting multiple Lansweeper components, select the other tab, click through any warnings and repeat the password changing process.
- Hit Save and restart the Lansweeper and web server services.
