# Initiating Remote Desktop Sharing

## How to establish Remote Control?

Remote Access Plus lets you remotely control and troubleshoot Windows, Mac, and Linux computers in your local network. In the on-premises version, remote control is also available for Android devices. Following are the steps to establish remote control over a computer in your Domain/Workgroup. Remote Access Plus uses the HTML5 viewer by default.

### Prerequisites:

1. Ensure to **add the domain/workgroup** under Remote Access Plus management. Learn how to add domain/workgroup [here](https://www.manageengine.com/remote-desktop-management/help/adding-domain.html).
2. **Ports to be configured** for Remote Control, Chat, System Manager, and File Transfer.

| TCP ports | Purpose |
|---|---|
| 8443 | secure remote connection |
| 8444 | remote connection |

**Enabling the UDP port 8443** will let your viewer directly control your remote agent. However, an initial handshake will happen via Remote Access Plus server.

### Establishing Remote Control

Once you have ensured that all the above prerequisites are met, you can establish a remote connection in the following ways:

1. From the **home page**, just type the name of the computer and establish the connection.
2. If you have recently established a remote connection with the computer, it will be listed in the "*Recent Sessions*" view, from where you can establish the connection.
