Or you can do it simply as follows.
- Run command prompt as administrator
- Execute this command
C:\AosService\PackagesLocalDirectory\Bin\Microsoft.Dynamics.AX.Deployment.Setup.exe --metadatadir C:\AosService\PackagesLocalDirectory --bindir C:\AosService\PackagesLocalDirectory\Bin --sqlserver . --sqldatabase axdb --sqluser AOSUser --sqlpwd AOSWebSite@123 --setupmode maintenancemode --isinmaintenancemode true
- Restart AOS service in IIS
- Go to and change those configuration keys
After finished, execute again above command with last parameter change to false. This is to disable the maintenance mode back to default.
The command prompt screen should show similar to this one.
