Install Standard Server 7.6

The first Horizon Connection Server must be a Standard Server. Subsequent Horizon Connection Servers are Replicas. Once Horizon Connection Server is installed, there is no difference between them.

A production Horizon Connection Server should have 10 GB of RAM and 4 vCPU.

  • In Horizon 7.2 and newer, each Horizon Connection Server can handle 4,000 connections.
  • In Horizon 7.1 and newer, each Horizon Connection Server can handle 2,000 connections.

Horizon 7.6 is the latest release of Horizon.

Horizon 7.5.1, Unified Access Gateway 3.3.1, User Environment Management 9.4, and App Volumes 2.14, are Extended Service Branch (ESB).

  • ESBs will be released once a year.
  • Once released, they will be actively supported for 24 months.
  • During those 24 months, there will be 3 scheduled Service Pack updates, SP1 will be released 6 months after the initial release, SP2 will be released 3 months after SP1, and SP3 will be released 6 months after SP2.
  • Service Packs do not include any new features.

  2. Request a new certificate with a common name that matches the FQDN of the Connection Server, or import a wildcard certificate.
  3. Note: the private key must be exportable. If using the Computer template, click Details, and then click Properties.
  4. On the Private Key tab, click Key options to expand it, and check the box next to Mark private key as exportable.
  5. In the list of certificates, look for the one that is self-signed. The Issuer will be the local computer name instead of a Certificate Authority. Right-click it, and click Properties.
  6. On the General tab, clear the Friendly name field, and click OK.
  7. Right-click your Certificate Authority-signed certificate, and try to export it.
  8. On the Export Private Key page, make sure Yes, export the private key is selectable. If the option to export the private key is grayed out, then this certificate will not work. Click Cancel.
  9. Right-click your Certificate Authority-signed certificate, and click Properties.
  10. On the General tab, in the Friendly name field, enter the text vdm, and click OK. Note: only one certificate can have vdm as the Friendly name.
  11. Then restart the VMware Horizon View Connection Server service. It will take several seconds before you can connect to Horizon View Administrator.

Horizon Portal ‚Äď Client Installation Link

If you point your browser to the Horizon Connection Server (without /admin in the path), the Install VMware Horizon Client link redirects to the VMware.com site for downloading of Horizon Clients. You can change it so that the Horizon Clients can be downloaded directly from the Horizon Connection Server.

  1. On the Horizon Connection Server, go to C:\Program Files\VMware\VMware View\Server\broker\webapps. Create a new folder called downloads.
  2. Copy the downloaded Horizon Client for Windows to the new C:\Program Files\VMware\VMware View\Server\broker\webapps\downloads folder.

  3. Run Notepad as administrator.
  4. Open the file C:\ProgramData\VMware\VDM\portal\portal-links-html-access.properties file with a text editor (as Administrator).
  5. Go back to the downloads folder, and copy the Horizon Client filename.
  6. In Notepad, modify link.win32 and link.win64 by specifying the relative path to the Horizon Client executable under /downloads. Note: In Horizon Client 4.3 and newer, there’s only one Horizon client for both 32-bit and 64-bit. The following example shows a link for the Horizon win64 client.
    Client for Windows:link.win64=/downloads/VMware-Horizon-Client-4.9.0-9539668.exe
  7. Then Save the file.
  8. Restart the VMware Horizon View Web Component service, or restart the entire Connection Server.

It will take a few seconds for the ws_TomcatService process to start so be patient. If you get a 503 error, then the service is not done starting.

Now when you click the link to download the client, it will grab the file directly from the Horizon Connection Server.

65 thoughts on “VMware Horizon 7.6 Connection Server”

  1. Hi Carl,
    at the Moment I am running 7.1.0 build-5170113.

    Is there a need to Upgrade? Do I lack Features/Performance/Security?
    Under the Hood there are Server 2012R2 Machines. I would migrate to a SRV 2016 if I had to reinstall.
    Our Environment runs fairly stable.

    Which Upgrades would you recommend?

    You are doing a great Job here. Via PayPal I would love to buy you a Coffee.

    Best Regards,


    1. See https://kb.vmware.com/s/article/52845 for info on Extended Service Branch.

      The downloads page for each version has a link to Release Notes for that version so you can see new features and bug fixes.

      If you’re doing App Volumes, then you might want to upgrade more frequently to get bug fixes and performance improvements.

  2. Hey Carl I have a question for you, love the View Horizon HowTo. I am install Horizon 7.6 in my home lab. My setup is kind of like yours in the howto’s that I have a .local domain and have a additional mycompany.com forwarder in the DNS server. I do own a wildcard SSL cert for mycompany.com. So I guess the question is do I use the cert on my connection server or stick to using a .local one. And my second question is which isn’t for this particular thread is when I get to installing the security server do I set the URLs up for the mycompany.com plubic address, adding the address to my DNS sever and do I use my single public IP as the PCoIP address or do I use the IP of the Security server? I use a pfSense firewall and HAProxy forward my HTTP/S traffic to my various servers.


    1. It depends on where you want to connect from. If from external, then you want the public IP. If you can modify HOSTS files, then the FQDN and certificate can be anything.

      Note: I would be using UAG instead of Security Server.

  3. Hello Carl!

    I am having this issue where i am creating desktop pools using Windows 7 (32-bits) and it keeps on initializing. Is this a known issue in 7.5.1?

  4. Something changed in 7.6 with HTTPS and Blast. Upgrading a (7.5) connection server to 7.6 and it broke my netscaler load balancing… Not sure what yet…
    I can bypass the LB, seems to work.. But if I try and use the LB, just says the services are down (HTTPS and BLAST)

    1. My issues seems to be on the netscaler, as I am getting a “Time out during SSL handshake stage” NS version 11.1 Build 57.11 nc

      1. Some NetScalers don’t TLS 1.2 ciphers in the default backend cipher group. I sometimes have to enable the Default SSL profile, then edit the ciphers in the backend cipher group. A network trace can show you SSL Handshake issues.

  5. Hi Carl, thanks for all your great articles. It seems like all of my horizon google queries get routed straight to your blog. Do you know if there is a way for horizon clients to authenticate as the vdm_user to windows 10 desktops and leave them at the windows login screen where they can then login? I am trying to create a more user-friendly login page for a kiosk zero client. Thanks!

  6. Good Afternoon Carl, I’ve create a Cert on my Connection Server 1, do i need to create one on my second Connection Server?

    1. You can export the existing cert and import it to the other server. Or you can generate a new cert with new keys on the second server.

    2. Thanks. Also my vCenter Server is a 6.5 VCSA, will it work? The reason I ask is that will not let me enable the storage size and gives me an error about bad username and password when I try to add it.

        1. Thanks for the info. I was able to get all my servers added in the Admin Console. Now I get a error when trying to login to the Horizon Client that the View Connection Server License key is invalid. Do i need a really key? Does it not run for 60 days with an eval key like vSphere?

  7. Hey Carl, thanks for the excellent guides – I’ve referenced them many times!

    Have you ever thought of doing one on VMware vRealize Operations for Horizon? It seems like a separate product that has its own intricacies and does not follow the Horizon or vROPs release cycle. For example, I’m using Horizon 7.4 and vROPs 6.7, but the latest vRealize Operations for Horizon version is 6.51.

    I believe many people have vROPs and would love to be able to get the advanced Horizon display protocol statistics, user session information, dashboards and alerts. A good guide on how to connect the dots would be very useful!

    1. FYI, vROPS 6.7 is not support on any version of Horizon currently. My ticket with vmware said you wont get proper data (if any from the desktops)

    1. So far, I’ve been unsuccessful with installing JMP. I keep getting a uem-migrate error about client certificate or database user.

      1. I keep getting that error. Documentation says you need to install the SQL cert on you JMP server in the local computer store. I did this but still no luck. If you uncheck use SSL for the DB connection it will install. I found that the ODBC it builds is using the SQL Server ODBC 10.0 drivers. I can’t get encryption working with them (SQL Server 2016). If I install 13.0 drivers and build the ODBC it works with encryption but the installer will replace the ODBC with the 10.0 one. I got it installed without encryption but cant get View registered with it. Keeps going between either JMP server is unrecognized or SSO Token error. I have set the time sync up on all the servers.

  8. Hey Carl,

    Great document!

    I need some guidance. I have 2 Horizon View 7.1 sites with about 120 VDI user sessions and 350 RDSH. vCenter Server 6.5 on both sites. Hosts are connected to vSAN 6.5 on a 10gb network.

    What are the design requirements to configure and install vROPS for Horizon 6.5.1 on Horizon View 7.1 or 7.3?

  9. Hi,

    I have installed horizon 6: the composer is on the same vCenter server and all is working fine. Now the task is to install the horizon 7, so I installed the View, Composer, Replica each one in a server. The vCenter is the same for both (Horizon 6 and Horizon 7). When I want to run a new machine on Horizon 7, I receive a message: clone error.

    ¬ŅDo you know what could be the issue in this topology?

  10. When trying to download the client “Horizon Portal ‚Äď Client Installation Link” going trhough the UAG I get a Error 404
    “No webpage was found for the web address:”
    HTTP ERROR 404

    If I go straight to the connection server it downloads the client file no problem.

    1. I am seeing the same thing. Internally the download works fine but when accessing from the Internet the browser says the file does not exit at the location specified. I am guessing the client installer needs to be copied to the UAG?

  11. Carl, Great info. Sorry it this is off topic but are you familiar with App Volumes, specifically which anti-virus software is compatible. We have a client that has all the appstacks working just fine, except when they have managed McAfee running on VDIs. Thanks.

    1. smadaras,
      It is not a good idea to layer antivirus software. Just put it on your master machine and it will be fine. We are using Mcafee MOVE configured like that and no problem here.

  12. Thanks for you docs and may i ask a question?I am on going a PoC in customer environment ,The customer wants to using Touch ID login to Horizon Desktop so I replicated default certification of Security and Connection Server by a certificate issue by internal CA, and the Security server has public to the Internet (Internal domain name is diffre the external domain name), I was installed internal CA root certificate in my iPhone 8 , But I can login to Horizon and the error is “Untrusted Horizon connection, VMware Horizon can’t validate your connection,Please contact your administrator”
    My Question is Can I using internal CA certificate to login the Horizon except the Horizon client option ” Didn’t validate server certificate”

  13. Hi Carl,

    First of all thank you for the really helpful blog.

    Could you please advise for one topic.

    I’m planing to upgrade Connection server which is on Server 2012 to Server 2016.
    Is it fine to create second Connection server as a replica which will be on server 2016 and after its been configured to disable the first (Standard) Connection Server which is on server 2012?
    Or should I export configuration from 2012 and import it to 2016?

    Thank’s in advance.

  14. Hi Carl,
    The HelpDesk Tool with the timing profiler shows 10 seconds to login, while the logon monitor logs shows 7.8 seconds, from what i checked with a stopwatch the timing profiler is much more accurate,
    how come? did you notice it too?

  15. Carl,
    I’m trying to do in place upgrade to 7.3 from 7.1. In the past was straight forward upgrade by executing the connection server exe. like you said in your notes Now for some reason installation it stuck on License agreement windows and it won’t go any further by clicking Next. There is no error message anywhere. I checked in the vminst.log I see this – “Found CEIP enabled flag HAS NOT been set.” End Logging.
    I don’t recall doing anything with CEIP during the install.
    Composer has been upgraded successfully without any issue.We have 3 connection servers and upgrade process is stopping on the same spot on all of them.
    Do you have any idea why installation is not continue?

    1. i had the same problem. the only solution was to deinstall the connection server and then reinstall the new one. it keeps all the settings…

      1. Thanks. I did that already and it was successfull, but then I had issue with provisioning machines from Composer. What option did you choose when installing the new one? I did Replica, but I didn’t remove my ADAM database. I couldn’t find any specific explanation if the database is upgraded during the install.

          1. Had similar Issues. Could get past the CEIP with support but other Problems let the installation roll back. Horizon 7.3 Downloads have been removed by VMware. Info from Support: Wait for 7.3.1 :-/

      1. I was able to upgrade by Christoff’s solution. Removing and installing the new version, but like I said in my comments you may have some other issues after that. Andreas also mention that he worked with the Vmware support and they suggested to him to wait for 7.3.1 version. I did check Vmware download site and currently there is no downloads available under 7.3.

    2. It is worth mentioning that VMware has pulled the 7.3 update from the site and is advising customers who downloaded it to NOT install at this time. There are some major production stopping issues if you proceed with the upgrade. They are thinking of releasing an updated release next week, according to what I was told on the phone.

  16. Hi. How do i configure same URL for external and internal traffic, if it is possible. With the current configuration trying to get the same URL, I am getting ssl validation error for internal traffic. Using wildcard cert in the setup.

    1. Internally, when you ping the DNS name, what IP does it resolve to? Is it a load balancer? If so, do you have a valid certificate on it?

      Are you internally connecting from thin clients? If so, did you push the root certificate to the thin clients?

      Do you have separate Connection Servers for internal? If so, did you disable the Secure Gateways?

      1. The DNS entry internally is one of the Connection Server (Standard one in my case) address. I manually change the DNS entry in case of a CS failure.

        I have 3 CS in the setup. All 3 has the Secure Gateway and Secure Tunnel are disabled in it. No separate CS for internal.

        When having the Secure Gateway and Secure Tunnel disabled, my external connection works fine.

        Internal connection get SSL validation error for blast connections thru HTML.

        1. Ok. That means the certificate installed on each Horizon Agent is not trusted. One option is to proxy the Blast connections through a Connection Server by enabling the Blast Secure Gateway. Another option is to use UAG internally. Another option is to replace the certificates on every Horizon Agent.

          1. I am using the same wildcard cert in the Horizon Agent as well. Just that I am not using the “”vdm” friendly name. Is that necessary? Tried it with friendly name as well. If this is wrong one for the Horizon Agent. Which one needs to be used? Tried to click cert which throws the error before it reloads, I could see the wildcard which I have installed.

  17. Hey Carl, thanks again for the great documentation! Just an FYI, first time i tried to log on to the helpdesk portal I received the following error: ‚ÄúAuthentication failed, invalid domain, username or password. Please try again‚ÄĚ.

    I followed Pascal van de Bor’s blog: https://pascalswereld.nl/2017/07/02/horizon-7-2-with-a-little-helpdesk-from-my-friends/ (Thanks Pascal!) to solved the issue.

    See for reference: https://kb.vmware.com/selfservice/microsites/search.do?language=en_US&cmd=displayKC&externalId=2144768

  18. It seems as if once we updated to 7.0.3, we are seeing a crazy amount of warnings. We are seeing a ton of “Unable to Launch pool…is not ready to accept connections” as well as The pending session for user…has expired” These are occurring on our internal pools as well as the pools our external users connect to. The parent VM has the latest client. I am at a loss as what this could be and i’m sure there are plenty of things it could be.

    We haven’t heard any screams about users being disconnected or anything along those lines, but those calls may not be getting through the helpdesk to us.

    Any ideas/suggestions? Anything would be appreciated at this point.


    1. It’s the securegateway.exe on the connection servers. I have had a total nightmare with this sofar and not resolved yet. My advise is to not upgrade to 7 if you are using secure gateways services for PCoIP connections.

  19. Just an addition to Horizon Toolbox and upgrading to a newer Horizon Connection server version.

    If you have Toolbox installed, make sure to uninstall this first before you do an in place upgrade on the connection server. The Tomcat service and Web component service freak out and Horizon View administrator won’t work after in place upgrade.

  20. Hi Carl, you’re blog is awesome! If you’re ever in Charleston SC I would love to buy you dinner. ūüôā Question: Do you know if Remote Assistance can be initiated in both directions? For example, can an administrator request to view a users desktop? Would need for the user to accept or deny the request…

  21. Carl thank you for this Post. it was really good. I’m impressed. I did run into an issue with the new version of Horizon Toolbox. I installed the new version 2.1.2. If I were to set a pfx file like you did and specified the new attribute keystoreType=‚ÄĚPKCS12″, Tomcat would not restart. Instead, I removed this extra setting, and then everything worked and the site was signed.

    Thank you again.

    1. It works for me in 2.1.2 with the keystoreType. I noticed that one of your quotes is a curly quote instead of a straight quote.

  22. Hello Carl! Tank you for this post. I have a problem, after the installation, I don’t see all of the Vmware services when i open the services.msc. I only have 2 services running: the blast secure gateway and the Security Gateway Component services.
    Do you know what can cause this issue?

  23. hey i like your blog. Just setting up Horizon 7 in my dev environment. I am looking at the replica connection server. I guess it functions exactly like a front end webserver that is load balanced behind an F5?

    1. Kind of. It also has an LDAP directory that replicates with other Connection Servers.

      The Connection Server is just a broker. It selects a Horizon Agent for the user and tells the user to connect directly to the Agent.
