Remote Desktop Services is Currently Busy Server 2016: Step-by-Step Guide

/ Knowledgebase, Remote Desktop Protocol (RDP)

Remote Desktop Services (RDS) is a powerful feature in Windows Server 2016, allowing users to remotely access applications and desktops hosted on a server. However, you might encounter an error message stating, “Remote Desktop Services is currently busy server 2016.” This error can be frustrating and disruptive, particularly in environments that rely heavily on remote access. This article will explore the common causes of this issue and provide step-by-step solutions to resolve and prevent it.

Compassionate the “Remote Desktop Protocol (RDP) Services is Currently Busy” Error

When users attempt to connect to a server running Windows Server 2016, they might see this error message for several reasons:

  1. Server Resource Overload: The server might be overloaded with too many active sessions or running processes, exhausting CPU, memory, or disk resources.
  2. Misconfiguration: Incorrect RDS configuration or group policies can limit the number of concurrent connections.
  3. Network Issues: Network bandwidth limitations or connectivity issues can cause delays and connection failures.
  4. Licensing Problems: Issues with Remote Desktop licensing can prevent new sessions from being established.
  5. Stale Sessions: Disconnected or orphaned sessions that haven’t been properly terminated can clog up resources.

Steps to Resolve the Remote Desktop Services is Currently Busy Server 2016

Step-1: Check Server Resources

    1. Monitor Performance:
      • Open Task Manager or Performance Monitor on the server.
      • Check CPU, memory, and disk usage. If any of these resources are maxed out, it could be causing the issue.
    2. Free Up Resources:
      • End unnecessary processes or services consuming excessive resources.
      • Reboot the server if necessary to clear all active sessions and reset resource usage.

Step-2: Manage Active Sessions

    1. View Active Sessions:
      • Open Remote Desktop Services Manager or use the Task Manager.
      • Go to the Users tab to see all active and disconnected sessions.
    2. Disconnect or Log Off Idle Sessions:
      • Right-click on idle or inactive sessions and select Disconnect or Log Off.
      • Ensure that users save their work before you terminate their sessions.
    3. Set Session Limits:
      • Open Group Policy Management.
      • Navigate to PC Configuration > Administrative Templates > Windows Components > Remote Desktop Protocol Services > Remote Desktop Session Host > Session Time Limits.
      • Configure settings for Set time limit for active but idle Remote Desktop Services sessions and Set time limit for disconnected sessions.

Step-3: Review RDS Configuration

    1. Check Connection Limits:
      • Open Server Manager.
      • Go to Remote Desktop Services > Collections.
      • Click on your collection name and ensure that the Limit number of connections setting is appropriately configured.
    2. Adjust Connection Settings:
      • Open Group Policy Management.
      • Navigate to PC Configuration > Administrative Templates > Windows Components > Remote Desktop Services > Remote Desktop Session Host > Connections.
      • Ensure that Limit number of connections is set to an appropriate number, considering your server’s capacity.

Step-4: Verify Licensing

    1. Check License Server:
      • Open Server Manager.
      • Go to Remote Desktop Services > Overview.
      • Ensure that the RD Licensing role is installed and configured correctly.
    2. Review Licensing Settings:
      • Open Group Policy Management.
      • Navigate to PC Configuration > Administrative Templates > Windows Components >
      • Remote Desktop Services > Remote Desktop Session Host > Licensing.
      • Verify that the Use the specified Remote Desktop license servers setting correctly configured with your license server’s name.
    3. Check License Availability:
      • Open RD Licensing Manager.
      • Ensure that there are enough licenses available for all users trying to connect.

Step-5: Network and Connectivity

  1. Check Network Bandwidth:
    • Ensure that your network infrastructure can handle the number of concurrent RDS connections.
    • Consider upgrading network hardware or increasing bandwidth if necessary.
  2. Reduce Network Latency:
    • Usage Quality of Service (QoS) policies to prioritize RDS traffic.
    • Minimize the use of applications or services that consume large amounts of bandwidth.
  3. Address Network Issues:
    • Troubleshoot and resolve any network connectivity issues.
    • Ensure that firewalls and network security configurations are not blocking RDS traffic.

Step-6: Update and Patch Server

    1. Install Updates:
      • Open Windows Update.
      • Check for and install any available updates for Windows Server 2016.
    2. Apply Patches:
      • Ensure that all RDS-related updates and patches applied to fix known issues and improve stability.
