The VMware Horizon is a tool that helps in the simplification of the management of all virtual desktops. In addition to that, it also provides a platform for cloud on-premise applications. In the case of hybrid or multi-cloud configurations, it provides a fantastic work-space environment as well as optimized software data center. 

While using VMware Horizon 7, which is the latest version, you might encounter some problems while working with it, eventually. In such cases, you have to perform some troubleshooting methods to fix and roll back the working environment in the previous condition. 

Various causes behind the Issues 

There must be some causes when the tool faces any type of problem. Without further ado, let’s check out what are the real causes behind the common desktop issues. 

  • Authentication failure
  • Receiving error messages
  • Unexpected session timeout
  • Presence of poor UX 

Resolving these issues might solve any type of problem occurring in the tool. Furthermore, it will also initiate a new session to the virtual desktop machine. 

The Troubleshooting Methods 

According to the analysis of tech experts, they have come up with a bunch of troubleshooting steps or solutions. This will help to resolve all the problems for desktop admins. 

1. Use the Help Desk Tool

This is actually the precaution for you regarding the facing of issues. Always try to use the desk tool to get assistance regarding the working sessions. You can also troubleshoot your desktop admin with the help of this tool as well. 

2. Use the VMware Logon Monitor

The VMware log on the monitor is also an important tool that is very much useful. After installing the application, it will help you in showing logs, performance reports, metrics, and others. In addition to that, it will also help you in troubleshooting the desktop system. 

3. Install VMware Performance Tracker

As the name suggests, the applications will help you in tracking all the remote desktops and monitors connected to it. It will also track and show you the pre-set protocols and system usages too. In addition to that, you can also create a pool and run the application as published. 

4. Fix the authentication of the client

When the LDAP (Lightweight Directory Access Protocol)  synchronization doesn’t perform, then there must be some authentication errors. In some cases, there might be issues in the connection of servers as well. So, first you need to check for any type of sync issues. If there is any, then open the Command Prompt and type “repadmin.exe /showrepl localhost:389 DC=vdi,DC=vmware,DC=int”. 

If this solves the issue, then it is well and good, if not then your system security software might resist the establishment of the connection. So, you need to temporarily disable your antivirus for some time. Moreover, you can also increase the limit of the desktop connection. Set the connection in such a way that desktop clients, with proper licensing, will only be able to connect. 

5. Stop receiving error messages

There are several factors for the occurrence of this error. There might not be a desktop pool present in your host system. In that case, check the system entitlements. If the desktop pool is present and the client stack is full, then it might also show error messages. You can limit the number of desktops in the server. 

On the other hand, when the application is not running somehow, you can also receive error messages. Check whether it is active or not, if not, turn it on. Finally, check the agent status of the virtual desktop connection and make sure that its status is active.

6. Make the availability of desktop remote session 

When the working session is tunnelling, then there is a high probability of being blocked by the firewall. If this happens, then the clients will get a black screen on their monitor. A desktop session might be unable to access the desktop because of the misconfiguration of traffic in the ports. 

All you need to do is to check all the pointer records and make sure whether they are working properly or not. In addition to that, check whether the name of the resolution is also functioning or not. In the case of HTML 5 user clients, open a different browser apart from the default one and it will work just fine.
