Agent unreachable vmware view kb


Many organizations are making use of VMware Horizon as the solution to enable a successful, effective, and efficient remote work environment. With that being said, issues may arise from time to time where your end-users may not be able to connect to the target machine in their desktop pool, whether virtual or physical. In order to troubleshoot Horizon effectively, you need to know your architecture in the Horizon environment. How does traffic flow from the outside to your Horizon desktop?

Also, what is the state of the agent on the endpoint machine.

VMware Horizon Client Error Couldn’t Connect to Server

Also, just basic troubleshooting methodologies here, but was the target machine working and then stopped? What has changed, anything? Note the architecture of the below diagrams. This connection should be successful. Using that trick can help to shortcut troubleshooting to narrow in on where the connectivity issue exists. If you can connect using one and not the other, this narrows in on a potential issue with a particular Connection Server.

If you have already ruled out the obvious reasons for connectivity issues, such as changing a firewall rule and other clients are connected just fine, you most likely do not have a global issue with the environment. Note what the status is for the Desktop machine configured for the desktop pool. If the agent is unreachable, the client will never be able to connect. Is the agent service running? Is the machine down? If the machine exists on a separate network, do you have network level connectivity to the machine in question?

Is NAT in play? With physical machines, I have had to implement a registry key in some environments for connecting successfully to remote physical workstations. This has been tested with Horizon 7 only and may not be needed with Horizon 8. However, it is worth trying if you are having weird issues not being able to connect to physical workstations with the Horizon agent installed.

Physical machines also do not like to have a user logged into the console and then a connection attempt from Horizon. It will either error or give a message that there are no sessions available.

However, what if your connection server does not have a route to that internal network represented by the local IP address? The Horizon Agent reports the discovered IP address of the machine on which it is running to the Connection Server instance. In secure configurations where the Connection Server instance cannot trust the value that Horizon Agent reports, you can override the value provided by Horizon Agent and specify the IP address that the managed machine should be using.

If the address of a machine that Horizon Agent reports does not match the defined address, you cannot use Horizon Client to access the machine. In this case, the vdmadmin command can be a lifesaver. You can use the vdmadmin command with the -A option to override the IP address reported by Horizon Agent.

Note the examples given by VMware :. Override the IP address for the machine machine2 in the desktop pool dtpool2. Display the IP addresses that are defined for the machine machine2 in the desktop pool dtpool2.

Remove the IP addresses that is defined for the machine machine2 in the desktop pool dtpool2. Remove the IP addresses that are defined for the desktops in the desktop pool dtpool3. There is a special registry key for this case. Note the VMware KB here:. On the virtual machine on which Horizon Agent is installed, open a command prompt, type regedit.I encountered an interesting failure message while performing an upgrade from VMware View 5. In this case, some desktops in an automated pool running the 5.

The 5. It specifically calls out this issue with a 5. When the View Agent is reinstalled or upgraded, it may change the keypair used to identify the View Agent with the Connection Server.

This issue occurs if the process of changing the key in the Connection Server configuration fails and, therefore, causes the communication between the View Agent and Connection Server to break. In my case, the 5. The suggested resolution in the KB for automated pools worked like a charm. The desktops running the older 5. This gives you some more breathing room to get your agents updated to 5.

It is probably best to change this back to Enabled once the older agents updated to 5. VMware explains the cause as being an agent upgrade or reinstall: When the View Agent is reinstalled or upgraded, it may change the keypair used to identify the View Agent with the Connection Server.

The current list of supported distributions are at the moment:. Make sure you have installed your Connection Server according to the best practices and that you can ping it and can resolve it in DNS.

For the installation I used Ubuntu The installation of Ubuntu is pretty straight forward. Of course the configuration itself needs some tweaking here and there for your organization. Remember though that you are creating a manual pool with multiple VMs in it, so every VM has te be created by hand. Make sure you use Gnome as your desktop manager. Check KB for more information on the distributions. Log into the virtual machine 3. Change to the directory with cd vmware-tools-distrib 8.

Before a Linux machine can be managed by Horizon 7, the machine must be able to communicate with Connection Server. You must configure networking on the Linux machine so that the Linux machine can ping the Connection Server instance using its FQDN fully qualified domain name.

For a complete list check out the Horizon 7 — prepare a Linux machine for Remote Desktop Deployment documentation There are also a couple of dependencies that you need to install. Which ones depend on the distribution. Check the complete list in the documentation. For my Ubuntu desktop I installed the update for indicator-session.

The -k is for the domain controller where the user account resides Kerberos. If you have trouble registering the agent, check your DNS settings.

Next to the password having characters that you need to escape not being able to connect to the connection manager by name is often the issue.
