RDS CAL licensing for middleware system written as a dispatcher to RDS

February 14, 2020, 8:50 am

Hi,

I am software developer and I'm working on web-based distributed system written from scratch in C++, which can work with RDS. In a nutshell, it is a wrapper or rather dispatcher giving accelerated access to virtual desktops.
My system is a middleware and stands between system users and RDS.
In fact, users DOES NOT have direct access to sessions in Remote Desktop, but only through the pool of available "channels" made by my middleware system.

Users are not using any standard Remote Desktop Connection applications nor these HTTP5 based Web Client, but just have access only through my own protocol.
Users might be authenticated by other than AD or AAD systems.

For example, my system provides access for 1000 users, but I know that at the same time, only max. 10 users will need to work simultaneously on the system.

So, is that enough for my middleware system to have 10 RDS CAL devices only, or despite everything, do I still need to purchase 1000 RDS CAL users?

Best regards,
Robert

Hello,

I am trying to install the RD License manager on a member of computer in AD. The AD Schema is Windows Server 2016 and this member computer is Windows Server 2019.

I have successfully installed the role and activated the server, added the member computer in the BUILTIN "Terminal Services License Server" group but in the configuration page I get the message "the system cannot determine if the license server is member of tsls group".

All the required ports are also open as specified by : https://support.microsoft.com/en-us/help/832017/service-overview-and-network-port-requirements-for-windows#method53

Does anyone have a similar issue or know how to solve this? I dont want to install any CaLs if the service has any errors.

Regards,

Tony

Connection Broker SQL setup.

Hi All,

So I understand that you cannot use SQL Express for HA connection broker back end because Express does not have any HA features native to the express version...but..

Can you use SQL Express as instead of WID as an RDS Connection Broker back endwithout any HA setup?

I'm trying to figure out how to create an RDS farm that is TLS 1.2 capable so that it meets our strict security auditing requirements so as I understand I need an SQL connection broker database to achieve this but I don't need HA, I just want to run a SQL Express database locally on my  RDSCB server capable of allowing TLS1.2 level encryption in the RDS farm.

Anyone know if this is possible?

Thanks in advance...

RDweb used to work but now says The user name or password is incorrect...

Hello,

Serer 2012 R2 used to allow remote connections through RDweb via internet. I am still able to login to the server on the internal network via RDP. I have been through and checked all the deployment options and SSL certs within server manager. I can access the web page fine, but its not letting me login with this error

The user name or password is incorrect. Verify that CAPS LOCK is off, and then retype your user name and password. If you continue to experience problems, contact the person who manages your server.

I have tried both logging in using both credential formats domain\user user@domain.xx.xx.

I have been through the event logs and cant see anything related. 

I have no gateway server. 

I have checked the firewall rules so RDP is allowed. 

Has anyone got any suggestions on how I can track down the issue?

Thanks

Hi,

Somebody's can help us what is causing of this error in Remote Desktop Connection. ? We Still have Window 7 pooled collection and everything is fine and working. And now we are provisioning the Windows 10 Virtual Desktop in the VDI infrastructure. After installation of windows 10  pooled collection in RDCB and have it created/Add  a 30 virtual Desktop we got this error during the connecting of our Wyse Thin client Device. 

Is there any steps need to check on this. ? 

Current Infra:

2 RDCB

2 RD Virtualization Host

1 RD gateway server (w/ DMZ switch )

1 RD web Page server (w/ DMZ switch )

1 RD Licensing Server Role

1 File Server

2 SQL Database Server Node

Checked and Verified the following : 

1. Windows 10 Master Image have been sysprep properly in the Session Host.

2. Created a Windows 10 Virtual Desktop properly.

3. Path to the correct cluster storage volume, parent disk and user profile disk. 

4. Ensure that Windows 7 profile disk, CSV and parent disk folder is separate to windows 10 pooled collection. 

5. Windows Server 2016 Version.

6. 2 times to recreate all VM's and collection in the RDCB.

Multiple RDS sessions just for management?!

February 17, 2020, 11:03 am

Hello.

I heard that phrase before "There is no stupid questions, only stupid answers". I am going to challenge it.

Here is a stupid question that I came up with and I do not remember seeing it asked or answered!

Our techops need to have simultaneous access to administer certain application servers. Until now, they used direct RD connections that limited them to 2 simultaneous sessions. I have deployed server 2016 RDS infrastructure, installed RD Session host roles on those applications servers, that they managed, placed them in one collection, installed User CALs and voila. The techops add RDS gateway in the RD properties and happily connect to the servers.

Have I achieved the requested goal?

What did I just give them - an environment which they can now use as remote users (aka VDI) or the way to have more than 2 simultaneous connections or the combination of the 2 ?  Which option for a session type would be better: pooled desktop session or personal desktop session?

Thank you.

Network Stability and Remote Desktop Blamed For Intermittent Database Error

February 12, 2020, 10:31 am
$

0

My company is using a software package which is installed on RDS. All users access this program via Remote Desktop. The program is a business application which directly executes CRUD operations on a Pervasive database (no middle tier!). Our RDS server and database server reside in the same room (actually on the same vm host). Some of our users are remote over a VPN tunnel. These were the main reasons I wanted to install on RDS, because software updates and stability would be a nightmare if the application was installed on individual PCs, most notably with some running remotely. This setup would promote more stable execution because the servers are local to each other.

On occasion, the software produces database errors.

Certain errors are reoccurring, and the software company blames the issue on dropped packets. They claim desktops using a wireless connection can cause issues. They claim that this corrupts cache files and causes the database corruption.

I'm under the impression that RDP should generally negate any network issues because the application is executing on the server, not the PC. If a connection is interrupted, the application should continue to gracefully execute in the background until the session is reestablished.

On a setup like this, is it at all possible (or even heard of) to introduce database errors via RDP? Any thoughts?

Thank You.

Server 2019 RDS administrative session shadowing works, but shows a black shadow window

February 12, 2020, 12:38 pm

Hi there !

On a Server 2019 properly set up as a domain member with activated RDP services ("quick access" method), the "collection" is displayed correctly in the server manager; including the registered non-administrators or the normal remote desktop users.

The server is currently in the evaluation phase and only runs for 7 days. Neither CAL's nor product keys are entered, but that shouldn't matter at the moment, right?

Click right Mouse click on a user provides the option "shadow". When triggered, the correct small dialog comes and the window also opens. But it is white and when you enlarge the window you see a black picture with a white square in the middle. => the shadwing works, but shows nothing reasonable.

There is an RDS tool from Lizard, which delivers the desired monitoring result perfectly on another server 2019, which is single, i.e. not a domain member. Of course, I also installed this on the domain member server and expected success. But this tool also led to the absolutely identical result as the session monitoring via collection: black screen with white square in the middle.

The domain has the 2008R2 level.

The additional test carried out on both servers with the installed RDS Manager 2008 (tsadmin, that's fine!) Led to the result that everything works perfectly except for the session seal: there it also works perfectly up to the short dialog window and then it says " Access denied! ".

Can someone - best of all from Microsoft perhaps? - tell me what's going on?

It makes no sense to start up a new terminal server whose sessions the administrator cannot monitor.

With regards
Chris

Good day,

I need assistance with my Server 2019 STD. I would like User to connect from any Computer to my Server 2019 using RDS, logging in from the computer and using programs, and I need to know what rolls I need to install and all the services I need to make this work. I do not want to use Per user Device Cal's.

I was reading if I use per device cals then it is locked to that Hardware device and the User can only use that device to log into the server.

Can someone please share some knowledge in how I am going to do this?

RDS Host third party app listening port redirection

February 12, 2020, 7:33 am

This is the scenario:

I have a 3rd party application that brings up a listening TCP port for communications purposes. 

This applications has a preconfigured listening port, lets say 49000, but the fact is the port is not available. 

Testing this issue with iperf has brougth some info to light: Windows somehow redirects the listening port to a random TCP port, starting at 20000 and assigning it "randomly". Here are some pictures:

iperf acting as server (netstat shows the port 42500 is not listening):

Client failing to connect:

processexplorer to check the listening port:

Succesful connection with the redirected port:

Nestat with redirected port:

This behaviour seems reasonable, otherwise only the first user to turn on the applicacion would be able to actually use it but I haven't been able to find some information that explains how this process work and why does it do.

I can't find any information about it and I would like to know if I am right or there is another cause for this beaviour as well as know if there is a workaround for this app to run.

RDS 2019. 120 licenses available, users being disconnected every 60 minutes.

Hi,

We have a Windows 2019 RDS farm with 2 session hosts. Our license server has 120 CALs available. A GPO directs the session hosts to the license server.

After a month of deploying it, our users started receiving the error:

 “There is a problem with your remote desktop license and your session will be disconnected in 60 minutes. Contact your Administrator to fix this problem.”

Running RD Licensing Diagnoser on the session host showed that 50+ "Per User" licenses were available. Unable to find a solution I ended up rebuilding the whole farm from scratch. Today (a month later) the problem returned.

Deja vu, running RD Licensing Diagnoser on the faulty session hosts tells me that the license server is up, 55 out of our 120 licenses are available, and that the licensing mode is “Per User”.

The problem first affects one of the session hosts, then later the other. I see no errors or warnings in Event Viewer concerning the licensing services on either the session host or licensing server.

We have another RDS farm still running 2016 on this domain, and it has not displayed any of these problems.

Any help would be appreciated. I’d rather not rebuild this farm with 2016 (which is the only path I see to fixing this).

Second broker not functionning

Hello,

I need your help.

I have a RDS FARM with 

8 host session (named RDS01, RDS02...)

2 Brokers (BRK01 and BRK03)

1 Management (MGM01) where we deployed the farm and see the collection, and with the SQL server for broker HA

DC is on another server

Everything is in 2016 version, windows server 2016, SQL server 2016

My connection chain : Driver={ODBC Driver 13 for SQL Server};Server=MYENTERPRISE-MGM01,1433;UID=sa;Pwd={password_replaced};Database=RDFarm

DNS name for the mstsc connection : RDS.MYENTERPRISE.LOCAL

collection name : RDS-MYENTERPRISE

name of the DB : RDFarm

Round robin on the dns between the 8 host (RDS01,...)

Problem : The second broker for the HA is not working. 

We had BRK02 but with many problems, so we created a new server : BRK03. 

But BRK03 is not working too

When a RDS Host is going through BRK01, everything is ok, we see users in the connection of the collection on the MGM.

But when RDS Host is going through BRK03, we don't see the users in the collection, and users got temp session when disconnect/connect.

In the events on BRK03 :

Windows Server 2012 RDP - An internal error has occured - intermittent

Hi there,

In my environment we run 4 virtual windows server 2012 R2 plus a host on the same. Occasionally on the Main domain controller I will receive and RDP error from one of our sensors on our monitoring software (PRTG), when trying to remote in it will pop up saying, unable to connect and internal error has occured. It is very random, some days it wont happen sometimes it may happen once, it could happen 3 or 4 times at random intervals in a 20 minute period, the sensor also monitors the response time for RDP and it just seems to timeout. We have a sonicwall firewall in between the server and the outside world. I have tried changing the connection properties on windows firewall as well and other suggestions don seem to apply to my environment. Would anyone have any suggestions.

Kind Regards

RemoteApp : Caps Lock / Num Lock become inverted in RemoteApp sessions. Server 2012r2 and 2016

June 5, 2019, 9:46 am
$

0

This issue has been a thorn in my side for the past several months. While investigating I've read every post/article I could find on the topic and wanted to share my findings, as well as include instructions how to recreate the issue which I haven't seen elsewhere. 

Symptom:

In Server 2012r2 and Server 2016 RDS environments, while in published RemoteApp applications, the Caps lock/Numlock keys become inverted from the local computer. For example, the keyboard indicator shows Caps Lock is off, but capitalizes all characters in the RemoteApp application.

Cause:

The Caps Lock/Num Lock keys are inverted when the application opens a new window, a text field is selected, and the “Caps Lock” or "Num Lock" keys are the first input. It appears that when new Windows are generated from the published application they don't get keyboard sync information until text is input. For instance, if you launch a published instance of File Explorer, click the search bar, and hit the "Caps Lock" key, the issue doesn't happen. However, if you right click a folder, select"open in new window", click the search bar in the new window, then hit the caps lock key, it will. Again, only if the Caps Lock/Numlock keys are the first input.

You can recreate the problem easily by doing the following:

  1. Publish "Notepad" in your RemoteApp environment
  2. Launch "Notepad
  3. Go to File -> Open
  4. Select the "File name:" field
  5. Press the "Caps Lock" or "Num Lock" key before pressing anything else
  6. The caps lock/num lock key will now be out of sync

I have tested this in several applications including: Adobe, WordPad, Word, Excel, PowerPoint. This also works in clean installations on both Server 2012r2 and 2016.

Solution:

Currently none. We placed a paid ticket with Microsoft Support where we explained the issue and provided instructions on how to recreate. The ticket was escalated, and we were eventually informed that this is a known issue that hasn't been documented. We were then provided a refund and informed that they would let us know when a fix is in place.

Workaround: 

Clicking anywhere outside of the RemoteApp applications will correct the inversion. We typically recommend clicking the task bar. Another option is minimizing and maximizing the application manually or by pressing Win+D twice. Many of our users use the caps lock key in place of the shift key. I'm not sure how effective it has been but we are instructing users to use the shift key, especially when entering credentials. 

Even though there isn't currently a solution I hope that this is at least informative and someone finds it helpful.

Users fail mostly connecting to load-balancing farm, but only when going through a VPN

February 6, 2020, 8:50 am
$

Hello everybody,

A customer runs Windows Server 2019 terminal server farms. From the local network, everything is fine. Users get perfectly connected and load-balanced to the RD servers. However, if the log on to the domain through a VPN (TMG 2010) which does not block any traffic, they can only only sometimes connect to the farm. When they fail, their Windows 10 RDP client just yields an "internal error" without being more specific.

We checked already:

* TMG does not block anything coming from the VPN to the inner servers or vice-versa. We also tried temporary firewall rules allowing any traffic in both directions.

* DNS resolution and contact to the domain controllers is fine from the LAN and through the VPN. There are DNS A records for each RD server, and for each RD server there is a DNS A record with the farm name, pointing to each of the RD servers, for DNS round-robin.

* The RD broker (a separate server) load-balances the users just fine.

* The clients get a DHCP address for their VPN connection from VPN, also just fine.

* The clients CAN connect every time to the old 2008 R2 server farm which did not load balance. When they try to connect to a 2019 farm (with each farm consisting of 4 RD servers and its own broker and licensing server), the only connect sometimes, the other time failing with the "internal error".

* The clients connect (locally and through VPN) using the same .rdp file pointing to the farm name. The do not use RDWeb currently, nor a RD gateway.

We have the suspicion (although not proved 100% yet) that the users can connect when a RD redirection is not needed/requested by the RD server that they initially contact via DNS round-robin.

Is such a symptom known? Does anyone have a clue what is happening here?

Best Regards, Stefan Falk

-2 RD Web Access (HA configured)

-2 RD Connection Broker (HA Configured)

-1 RD Gateway e Licensing

-2 RD Session Host

OS: Windows Server 2016 64Bit

I have already performed these steps:

-GPO "Allow audio and video playback redirection" (enabled)

-GPO "Do not allow supported Plug an Play device redirection" (Disabled)

-GPO "Allow RDP redirection of supported RemoteFX USB devices from this computer" (enabled)

-GPO "Enable RemoteFX encoding for RemoteFX client designed for WIndows Server 2008 R2 SP1" (enabled)

-In the Broker Server i have run in powershell --> Set-RDSessionCollectionConfiguration -CollectionName "CollectionNAME" –CustomRdpProperty “usbdevicestoredirect:s:*”

If i connect by RDP the webcam works fine but not in RD Web Access.

Thanks for your help!
