Check installation
The IQ4docs installer makes many settings automatically. If the installer makes settings to Windows components, it can happen that these cannot be set, e.g. due to legal restrictions or similar. In this case, the installer continues without being able to set these settings which are important for IQ4docs.
Check the following areas and make the necessary settings by hand if necessary.

The webserver IIS (server role) is automatically installed and configured. The following settings are made:
- Webserver (IIS) > Webserver > Security > Windows Authentication
- Webserver (IIS) > Webserver > Application Development > .NET Extensibility 4.6
- Webserver (IIS) > Webserver > Application Development > Application Initialization
- Webserver (IIS) > Webserver > Application Development > ASP.NET 4.6
- Webserver (IIS) > Webserver > Application Development > ISAPI Extensions
- Webserver (IIS) > Webserver > Application Development > ISAPI Filters
- Webserver (IIS) > Webserver > Application Development > WebSocket Protocol
For FTP transfer, the FTP server is also installed:
- Webserver (IIS) > FTP Server > FTP service

The .NET framework must already have been installed before the installation. The installer automatically makes the following settings:
- .NET Framework 4.6 Features > WCF Services > HTTP Activation

The system user, for example, who runs the application pools, is either created or an existing one is used, depending on the selection in the installer. Check whether the user was created and all settings have been made. You can find out which settings have been set or need to be checked under Change System User.

Check whether the required Windows services have been created and started. The corresponding destinations are as follows:
- IQ4docs Mongo DB
- IQ4docsRabbitMQ
You can also check if the RabbitMQ is running by going to http://127.0.0.1:15672 on the computer running the service. The login of RabbitMQ must then appear.

Check if all application pools of the installed IQ4docs microservices are running (in IIS Manager). In addition, you can check the configuration of the services, which is very important especially in large installations (clusters, data distribution, client system), see Checking the system configuration.

To enable access to components of the IQ4docs system, required ports are enabled in the Windows firewall. The rules created automatically for this purpose are marked with IQ4docs in the name. You can find out which ports must be enabled under Network Ports.

A Windows task is automatically created for the backup of the database. Check the task as described under Database Backup.
