In part four, we performed the last of the procedures in completing our redundant RDS farm. We installed SQLprepped the connection brokers, went through the high availability wizard, added our second connection broker server and finally, we created our external load balancing virtual server.

Here in part five and the final of this mini series, we can at last test our setup! The moment of truth. If you do see this page, then it is definitely a good sign as it shows you are able to connect to your back-end servers through the Netscaler! Login in with one of your test user accounts that have been assigned permissions to access your session collection. You should now see the resources the user is allowed to connect to.

In this scenario, the user have access to a session desktop that is being load balanced behind the scenes on our two remote desktop servers. Now here comes the true test. Click on the resource to launch it. As this is only our lab, we should be okay to proceed so hit the Connect button and then the Yes button at the second prompt afterwards. If everything has been configured accordingly, you should now be logged in to one of the two session hosts in your lab!

Click on the Connection Info icon on the top status bar and it will let you know. To test the load balancing portion of your session servers, simply login to a different user account from a second computer. Chances are that this second user will be placed on the other server.

This here shows the connection broker load balancing at work by directing users to a session host they should connect to when they want to connect remotely.

To test the session re-connection feature of the connection broker, in your session simply open up a couple of apps and files. A caution prompt will then appear letting you know that your session will still be available the next time you reconnect. Hit OK. Logout of RD Web Access and re-authenticate. We configured exactly that when we configured our Netscaler in the previous articles.

With a RD Gateway, all user traffic will flow through the gateway. With load balancing in the setup, it may be a little difficult to track which gateway a particular user is using.

Remote Desktop Server farms explained (Part 1)

Luckily this is a lab and so we have the benefit of logging on one user into the farm to generate traffic.

We can then look at the ethernet adapter performance on both of our gateway servers to see which one has the higher traffic. Whichever one this is will be the gateway used by our lab user. To test the load balancing aspect, simply login as a second user and if UserA was using the first server as the gateway, then UserB should then being using the second server.

To test the high availability of our RD Gateway and Connection Broker pieces, I simply connect as a user, stream a video and then proceed to shutdown the gateway server the user is currently using. Because both of my servers has both the gateway and connection broker role installed, either one should be able to pick up the slack when either one of them goes out of commission either planned or unplanned.

Once you determine the server being used, simply power it down to simulate an outage.So when we deploy Remote Desktop Gateway, this is a server that sits usually in a DMZ or a perimeter network that acts as a middle-man. The external user connects to the Remote Desktop Gateway. They are authenticated by the Gateway, and the Gateway makes sure that they have permissions to access internal resources.

The Gateway sits in the middle, so historically the idea was that all the traffic going between the Gateway and the client is done using HTTPS SSL, which means we only have to open port in the external firewall. You also have to open up a number of firewall ports. On the external firewall you have to open up:. On your internal firewall you need to open up:. So a lot of ports have to be opened up in those firewalls for the communication to go back and forth. The idea is that very few ports need to be opened up in the external firewall because we want to make as small a hole as possible for the client to come in.

Our first step is to install RD Gateway role. Access your Connection Broker server and be sure to add your gateway server to all servers. In the Remote Desktop Services node you will notice that RD Gateway is not set-up and you can start configuring it by clicking on green icon marked on the picture below. First of all, the certificate names much match the external name of the RD Gateway. We need to make sure that the rd. The client must trust the certificate, and remember, trust means really two things, the CA certificate must be in the Trusted Root Certification Authorities store on the client, and the client must be able to contact the CRL, Certificate Revocation List, to make sure that the certificate is still good.

Now if you want to use the certificate for more than one role, you can also create a certificate that would have a wildcard and be good for anything that ends in nm. I have a wildcard so I will use it for all roles. Now very important to know is that there are two ways to apply certificates to the RD Gateway Service. Click on Select existing cert and configure it. Click on that and you will see users that connected through the RD Gateway.

They specify what users are allowed to connect through the RD Gateway. Double-Click on the CAP policy. I could also force them to use a smart card if I have smart cards in my environment. I can specify particular user groups. Notice by default all Domain Users are allowed in. So RAPs, R is for resources.

Supported configurations for Remote Desktop Services

What are they allowed to connect to? You will notice that we have 2 RAP polices. I can actually select an RD managed Gateway group or create a new one. If you are running earlier versions you will need to add connection broker as well in that group.

We could specify particular ports or we could allow connections to any port. If you are concerned with server performance, we can set a hard limit of allowed simultaneous connections. We can also disable new connections if we are performing scheduled maintenance on our server.

All active sessions will be disconnected, and then the RD Gateway Service will be restarted. So custom ports require RDP Client 8. Any of those clients can automatically adjust for the new port. When you have a farm it kind of works like this: Each member of the farm has its own individual name and IP address. We point the clients to the name and IP address of the farm, and then whatever the client sends out is given to all of the members of the farm, and they actually run an algorithm and they know which member of the farm is going to service the client.Once you have installed the Gateway role you would then need to export the policies from the first server and import them into the newly created.

Under the server Farm Tab add all the Gateway servers including the Farm name. In this example we use:. Ryan, specifically what does the RG Gateway farm do? Hi, Ryan!

Options For A Highly Available Load Balanced RD Gateway Server Farm on Hyper-V

For internal look like rdgwfarm. For external look like rds. Is that right way to do that? Now we trobleshooting an idle about 38 sec when we launch RemoteApp and on a client we used Sysinternals Process Explorer and saw, that clients mstsc connecting to both GW nodes simultaneously.

Is that normal? I thought, that client should connect to one of two nodes. Just a comment regarding the RD Gateway Farm. It is only there for backwards compatibility to guarantee affinity. Microsoft does not recommend this configuration due to the scale overhead on the RD Gateways.

You can avoid the issue by simply sticking to a hardware load balancer i. Of course this is only a how to guide, but for readers take note and have a look at my RDS Load Balancer posts. Hi Ryan. Is the farm name the name of the connection broker DNS farm name? It all depends on the server roles. I would recommend that you stick with using NLB or a Hardware load balancer. Microsoft does not recommend this feature for scalability. Appreciate your immediate response. I already have connection broker and session host high availability setup and stuck with gateway server role.

I cannot use hardware load balance or NLB. Please suggest high availability for gateway server role in Azure cloud. But i have the web access and getway server roles installed in same VMs. Please confirm. You would use 2 kemp load balancers in a active standby configuration. Both aspects are covered, load balancing of sessions across the gateways and in case of a gateway failure, you would have continued access to the service.Click Next.

When you click Deploy progress window will show up. After system restart check that all services configures successful and click Close.

Collections separate out RD Sessions Hosts into separate farms and allow admins to organize resources. I will replace that certificate with Trusted one a little bit later. Hit Next and Add. Wait until the role service is deployed and click on the Configure Certificate to review Certificate Options. Notice that the certificate level currently has a status of Not Configured.

The RD Gateway certificate is used for Client to gateway communication and needs to be trusted by the clients. Either install the self-signed certificate on all clients, or use a certificate for which the complete certificate chain is already trusted by all clients. As it said in the wizard, the external FQDN should be on the certificate. On Welcome to the New Zone Wizard page click next.

On Zone Type page accept the defaults and click next. It needs to be in. In my case I will use my private CA. If you are not familiar or if you do not have private CA, please take a look on my Mastering Windows Server series to learn how to install Certificate Authority. This opens up the certificate template snap-in. What we need to do is to pick one of these templates and copy it so that we can customize it for our purposes.

With remote Desktops most certificates that we need are for SSL. New Template Window will pop-up. There is a number of things we can do but the most important thing is permission. In real life you may want to lock that certificate down to particular people but in this case it is not important. I will also going to add in domain computers and give them permission to read, enroll and autoenroll. Click OK when it is done.

Now we need to take that template and Publish it to the CA. The last step is to enroll certificate. With an SSL we have to provide other information. Next we need to export the certificate with private key and configure gateway, rdwa, rdcb to use it. Welcome Export Wizard will pop-up.

What is Virtual Desktop Infrastructure (VDI)?

Select Yes, Export the private key and click next. If everything is good, we will not receive certificate error message.Use the following steps to deploy the Remote Desktop servers in your environment. You can install the server roles on physical machines or virtual machines, depending on whether you are creating an on-premises, cloud-based, or hybrid environment.

If you are using virtual machines for any of the Remote Desktop Services servers, make sure you have prepared those virtual machines. If you are providing and installing certificates from a trusted certificate authority, perform the procedures from step h to step k for each role. You will need to have the. Export self-signed public certificates and copy them to a client computer.

If you are using certificates from a trusted certificate authority, you can skip this step. Create a session collection. These steps create a basic collection. Check out Create a Remote Desktop Services collection for desktops and apps to run for more information about collections. You've now created a basic Remote Desktop Services infrastructure. If you need to create a highly-available deployment, you can add a connection broker cluster or a second RD Session Host server.

You may also leave feedback directly on GitHub. Skip to main content. Exit focus mode. Click Find Now. Select Restart the destination server automatically if requiredand then click Deploy. Select the virtual machine where the RD license server will be installed for example, Contoso-Cb1. Click Nextand then click Add. Accept the default values in the Activate Server Wizard. Continue accepting default values until you reach the Company information page. Then, enter your company information.

Accept the defaults for the remaining pages until the final page. This step might not work if you are using Azure AD Domain Services, but you can ignore any warnings or errors.

In Azure, this is the DNS name label and uses the format servicename. For example, contoso. Note If you are providing and installing certificates from a trusted certificate authority, perform the procedures from step h to step k for each role. Is this page helpful? Yes No.When you need to make the RD Gateway service highly available you have some options. When in comes to the actual load balancing of the connections there are some changes in respect load balancing from Windows Server R2 that you need to de aware of!

With Windows R2 you could do:. I prefer the first but all 3 will do the basic job of load balancing the end-user connections based on the traffic. The reason is that it uses two HTTP channels one for input and one for output and DNS round robin cannot guarantee that both these connections will be routed trough the same RD Gateways server which is a requirement for it to work.

TCP HTTP is can be used without it at the cost of a lesser experience and is also used to maintain the sessions and actions. These support a bunch of persistence options like IP affinity, cookie-based affinity, … just look at the screenshot below KEMP Loadmaster. But they also support layer 7 functionality for better health checking and failover.

Remember, removing single points of failure are like bottle necks. The moment you take one away you just hit the next one. This is actually used by their RDS template you can download form their support site. Hi Didier, cool article thank you. We often re-encrypt for example on the loadblancer. This site uses Akismet to reduce spam.

Learn how your comment data is processed. Buy me a coffee. These support layer 4, layer 7, geo load balancing etc. Software load balancing. With this they mean Windows NLB.

DNS Round Robin load balancing.

That sort of works but has the usual drawbacks for problem detection and failover. These support a bunch of persistence options like IP affinity, cookie-based affinity, … just look at the screenshot below KEMP Loadmaster But they also support layer 7 functionality for better health checking and failover.

Cancel reply.Why would you need a RDS Farm? What are the options? What are the scenarios? These are some of the questions we will answer in this article.

So why do we need a RDS farm? I highly doubt this but in case you are not convinced, read this paragraph:. There are several reasons for needing an RDS farm.

rd gateway farm 2016

Despite the fact that available hardware grows extremely fast especially with Server Virtualization, there is a point where it simply no longer performs to certain standards on a single RD Session Host. Another big reason of course is High Availability. Especially if you host a complete desktop on your RD Session Host for your users, downtime means those users can no longer perform their daily tasks.

Of course virtualizing your RD Session Host server on a server virtualization cluster like for example a Hyper-V cluster creates high availability of the hardware but that does not cover software issues on RD Session Host Server.

A third reason is maintenance. If you would be running one server, that could mean downtime for your end-users. If you are running a farm with multiple servers however, you could very fluently drain the server allowing existing connections to run, but deny additional new sessions in question until it is free of sessions without creating downtime to the delivered service.

Ok, so we know that our environment will have multiple RD Session Host servers, how does the workload get evenly spread over those servers in order to optimally use the available resources? This is where the term load balancing, a technique to spread workload based on several conditions, steps in. Now that we have multiple RD Session Host servers, can it be assured that in case of a network failure between the client and the server, I will return to the session I left open?

Yes, it can. Now that we know what a farm is, we are convinced that we need one and we know what functional challenges to face let us look at some possible scenarios and implementations, and discuss the pros and cons. Remember that the main reasons to implement load balancing are spreading the workload as optimal as possible, creating High Availability and being able to drain sessions.

Deploy your Remote Desktop environment

How does the load balancing work? Hardware load balancing basically has the same PROS as NLB but on top of that can, based on the type of hardware or software spreads users over RD Session Host based on better conditions than just the amount of sessions. For example, the available CPU or memory can be added as a measurement.
