You installed N-Linx Server on a computer in the network.

2. In the N-Linx Agent Setup window, select **MediaRecorder control** in the Drivers and Tools field and click **Next**.
3. Accept the terms in the End-User License Agreement and click **Install**.

2. In the N-Linx Server Address field, enter the Computer name of the computer with N-Linx Server. See [To find the computer name](https://bookstack.noldus.com/To%20find%20the%20computer%20name).  
    You can also enter the IP address, but then the IP address of the computer with N-Linx Server must be fixed. Ask your system administrator for assistance.  
    If MediaRecorder runs on the same computer as N-Linx Server, leave the entry localhost in the N-Linx address field. N-Linx Agent then automatically connects with N-Linx Server.

### To change the port

N-Linx Agent by default uses port 5672 to communicate with N-Linx Server. If this port is in use, type the new port after a colon in the **N-Linx Server Address** field. For example:

**<span class="FM_All_caps">IMPORTANT</span>** Select the same port in all components that communicate with N-Linx Server. Also, disable Windows FireWall for this port.
