Troubleshooting VMware Horizon Client vdpConnect_Failure Issue

  Introduction VMware Horizon Client is a widely used solution for virtual desktop infrastructure (VDI). However, users may encounter various connection issues, one of which is the vdpConnect_Failure error. This error often results in a black screen followed by a disconnection, preventing users from accessing their virtual desktop. In this article, we will explore the possible causes of this issue and provide step-by-step solutions to resolve it. Common Causes of vdpConnect_Failure 1. RPC Server Unavailable One of the most common reasons for vdpConnect_Failure is the unavailability of the Remote Procedure Call (RPC) server . This can occur due to: The RPC service being stopped or disabled Network issues preventing communication with the server Firewall blocking required ports 2. Display Protocol Issues (Blast/PCoIP/RDP) Horizon Client uses different display protocols such as Blast, PCoIP, or RDP . If there are misconfigurations or compatibility issues with the selected protocol, ...

Is the PCoIP Protocol Vulnerable to Tampering? And Are There Any Security Incident Cases?

  Is the PCoIP Protocol Vulnerable to Tampering? And Are There Any Security Incident Cases? The PCoIP (PC over IP) protocol is a remote desktop protocol that transmits screen images in pixel units, providing high performance and security. However, like other protocols, PCoIP cannot be completely free from tampering and security threats. Potential Vulnerabilities of the PCoIP Protocol: Software Vulnerabilities: If vulnerabilities are found in the PCoIP client or server software, attackers can exploit them to infiltrate the system or tamper with data. Network Attacks: Attacks that intercept or tamper with network traffic (e.g., man-in-the-middle attacks) can disrupt PCoIP communication or leak data. Authentication and Access Control: Inadequate authentication or access control settings can allow unauthorized access and expose the system to risk. Security Incident Cases: Recently, HP discovered several security vulnerabilities in Teradici PCoIP software. The most serious vulne...

VMware Horizon Agent “Protocol Error” — Fixed by Windows Firewall Configuration

  🖥️ VMware Horizon Agent “Protocol Error” — Fixed by Windows Firewall Configuration Overview Recently, I encountered an issue where several Horizon Agent–based virtual desktops in our environment showed the status “Starting other services” or “Protocol Error” in the Horizon Administrator console. Even after reinstalling the Agent (version 2206 ), the problem persisted. Symptoms Horizon Agent status: “Starting other services” → “Protocol error” Horizon main services appeared to be running normally Event Viewer showed Event ID 7000 for services such as: PASVC – failed to start LUFAV – not installed Reinstalling the Agent (even using Repair mode ) did not solve the issue Root Cause After deeper inspection, we discovered that on the affected VMs: Windows Defender Firewall (Domain Profile) → “Block all incoming connections, including those in the list of allowed apps” was checked (enabled). This setting silently blocks all inbound traffic , ev...

vSphere HA Agent on a Host Cannot Reach Management Network Addresses of Other Hosts in vCenter

Troubleshooting: vSphere HA Agent on a Host Cannot Reach Management Network Addresses of Other Hosts in vCenter If you're encountering an issue where the vSphere High Availability (HA) agent on a specific host in your vCenter cluster cannot connect to the management network addresses of other hosts, it can prevent vSphere HA from functioning correctly. This means virtual machines (VMs) might not restart automatically in the event of a host failure. Here's a breakdown of troubleshooting steps you can take to resolve this: 1. Verify Network Connectivity:  * Ping Tests: From the problematic host, initiate ping tests to the management network IP addresses of your vCenter Server and other ESXi hosts within the cluster. This will help determine basic network reachability.  * vMotion Network: Ensure the network configuration used for vMotion is correct. If vMotion traffic is isolated on a dedicated VLAN, verify the VLAN settings, including switch configurations, are accurate.  *...
