Black Screen for Users in RDS 2016

July 24, 2018, 10:59 am
$

0
Windows Server 2016 RDS setup with one DC and 3 session host servers, all running as VMs under Citrix XenServer. This is a session-based deployment for RDP sessions.

Occasionally (that means approx every 7-10 days), new users logging in to RDS get a
black screen. That is, they can successfully log in but then see only a black screen, no task bar, nothing. Users can see moving mouse cursor, and they can bring up the Task Mgr with Ctrl+Alt+End. Sometimes, after 10-15 minutes the user desktop becomes visible, but most of the
time it never does.

Normally, every additional user logging in after this occured also gets the black screen. The only solution is to reboot this session host server.

The servers are updated to PT (July 2018).

Note - I installed an additional session host server recently and noticed that this phenomena does not seem to happen on that one (at least not as frequent). Same update status but was installed from later download media (evaluation edition download from internet, then converted to Standard edition by inputting a license). They do, however, all show the same build number in the settings app: 14393.2248.

So is it recommended to make a new install for all session host servers? Do not really understand why I would have to do that. They have the same update level, just one was installed from a later base media - but it's the same edition. Doesn't a server end up with an identical setup no matter what original media file was used, with all the updates? That should be the point of the updates, or not?

Or is there any other underlying reason for the black screen phenomenon which I should address?

Unable to RDP onto Server 2008

Since yesterday all users have lost the ability to RDP onto our Server 2008 machine, we are getting the error "The login attempt failed" when using the correct domain credentials as before. We have tried using local credentials to RDP and that also did not authenticate.

Other points.

  • Server is listening for Port 3389
  • Connections are allowed from Remote settings
  • Users are added to the remote users group
  • Terminal services are up and running

We're not sure what could of possibly happened to cause RDP to suddenly stop authenticating?

Any insight would be much appreciated.

2016 server / Remote Desktop Services Manger / Powershell

I am looking for the quickest way to shadow a users session in a 2016 RDS / Terminal Server environment. I would BE FABULOUS if i could use some syntax to connect directly to a session based on user name. I can query a server and get all session. I know i can go to my RDS host and get to them but the 2016 /2012 implementation of RDSM is terrible. what methodologies are you all using to do so. Please do not just paste Microsoft KB articles i have google for that. I want real world experience dealing with this. also if i have to query per server anyone ever query all servers at the same time to pull all sessions instead of per server?

Remote Desktop Services server in different domain from License server

March 21, 2019, 9:12 am

Following the best practices guide: best-practices-for-setting-up-remote-desktop-licensing-terminal-server

I've got a remote desktop services server running in a separate domain from the server holding the RDP licenses.  I've created a forest level 2-way trust between these 2 domains and added the license server to the Terminal Server License Servers group  in the trusted domain.

When I try to configure the RD Services server to point to the license server in the other domain I get this:

The license server specified is not valid. Verify the server name and specify a valid server name before saving the settings.


Nonetheless, I can proceed.  When I look at the RD Licensing Diagnoser I see:

The Remote Desktop Session Host server is in Per User licensing mode and No Redirector Mode, but license server rdplicense.domain.local does not have any installed licenses with the following attributes: Product Version: Windows Server 2008 or Windows Server 2008 R2



BUT... selecting the server shows these details:

TS or RDS Per User CAL    Windows Server 2008 or Windows Server 2008 R2

RDS Per User CAL             Windows Server 2012

So clearly there are CALs in place.



1. Both the RD Services Server and the License server are Windows Server 2012 - why is it looking for 2008 CALs??

2. There are 2008 CALs available, why is it complaining?

3. I'm assuming license usage goes up and down as users login and out, but the 2012 CALs don't seem to be getting returned.  Is there a way to force it?

4. Is any of this related to the "license server not valid" error I see when specifying this server in the first place?

5. Users are occasionally seeing the "No Remote Desktop license server is available" popup on the task bar.



I suspect there's a critical step I've missed in all of this.  Can anyone point me in the right direction?

Non-persistent RDS environment

Hello everybody,

I have searched all over the internet for an answer to the question "how do I set up a non-persistent RDS environment?".

But I still haven't found it. I know that you can accomplish this by going the VDI route and setting up a non-persistent VM.

This is not what I want or am trying to set up. 

I do not want the users to have personal desktops/folders stored localy on the RDS host. They have to be removed or reverted to an earlier state.

The "temporal folder" option in the RDS setup does not provide the desired function. And I cannot find any other option to make the user sessions and folder truly temproal.

I would really appreciate the help.

Best regards

Policy to logoff Active but Idle sessions after a set time does not work anymore.

I upgraded several Remote Desktop servers from Windows Server 2008 R2 to Windows Server 2016. One of the problems I have now is that the Group Policy settings that allowed me to logoff Active but Idle Remote Desktop sessions after a period of time online no longer works. Interestingly, if they disconnect, the Group Policy setting that allows disconnected sessions to be logged off does work. Anyone with any suggestions?

Hi we have a mix of new and old HP thin clients. 

I have 2 RDS session Hosts (server 2016) and one of them is the Broker. 

Some of the thin clients do not have a setting for broker address or load balance URL 

should i just use DNS round robin to load balance between the 2 hosts ?

I would like to use User Profile Disks. - Is this supported with DNS round robin?

RDS clients not connecting

windows 2012 r2, hyper-v, clients connect via rds website and then launch a rds session (vdi windows 10 vm). It was working, but then a few users reported being unable to connect. Silly me, I figured "apply latest updates and reboot" and now no one can connect. I updated and reboot the RDS and Hyper-V server (RDS is actually a VM running on the same Hyper-V server).

From the RDS server's RemoteDesktopServices-RDPCoreTS log a connection looks like this:

Event ID 131, the server accepted a new TCP connection from client blah blah blah

Event ID 65, Connection RDP-Tcp#0 created

Event ID 141, PerCounter session started with instance ID 0

Event ID 133 the following network characteristics have been detected for tunnel 8;...

Event ID 132, a channel rdplic has been connected between the server and the client using transport tunnel 0

Event ID 132, a channel rdpcmd has been connected between the server and the client using transport tunnel 0

Event ID 98, a TCP connection has been successfully established

Event ID 100, the server has confirmed that the client's multi-transport capability. (really bad English there BTW)

Event ID 130, the server has initiated a multi-transport request to the client, for tunnel 1

Event ID 130, the server has initiated a multi-transport request to the client, for tunnel 3

Event ID 135, the multi-transport connection finished for tunnel 1, its transport type set to TCP, reason code 3 (no UDP packets received)

Event ID 135, the multi-transport connection finished for tunnel 3, its transport type set to TCP, reason code 3 (no UDP packets received)

Event ID 103, the disconnect reason is 1033

Event ID 102, the server has terminated main RDP connection with the client

I've found articles about RemoteFX and disabling it via GPO and registry values - which I tried to no avail.

HELP!!! please!

RDP Reconnect sending bad password || Windows Event ID 4625: An account failed to log on

Issue: User Logs onto Client Machine remotely, then connects to Corp VPN and does RDP to any Corp machine. In case the VPN disconnects or client machine loses network connectivity momentarily, the RDP session re-establishes the connection.  When it re-establishes a connection, it logs a bad password attempt on the users account.  If this happens too many times, users are experiencing account lockout.

Upon checing the logs, I see that the Terminal Service is sending the bad password.

Can anyone suggest what could be the possible issue?

How to change password in RDP session

In my situation all RDP clients are remote over the internet. their passwords expire every 60 days. How can the user change their password before it expires? CTRL ALT DEL will not work because it takes you to a password change on your local machine. Note the users have no access to a desktop only a single application is forced to run through the user profile.

Privacy on a Terminal Server

March 19, 2019, 9:46 am

Hi,

to prevent users from knowing about other users on a terminal server what can I do?

By default users could:

-browse c:\users\*
-use taskmgr.exe
-tasklist
-qwinsta
-netstat
-? perhaps other commands, applications

to gain information about other users on a Terminal Server like Account Name, processes used, Network Connections.

I could prevent access to the obvoius like eventvwr + other administrative tools, c-drive or adjust permissions on qwinsta.exe but with cmd.exe and taskmgr.exe it already is difficult because it limits users e.g. from ending a hanging process.

Ideally it also would require to whitelist every single allowed application and prevent execution of portable software for users.

Are there any recommendations?

thank you

2012 r2 RDS Hosts logging users off

March 16, 2019, 8:30 pm

I have an issue I have been attempting to diagnose for about a week now. I only posted a few times ever and I am not used to requesting assistance so, please if there is anything I should have obviously mentioned just ask and I will fill you in. 

Little background. My primary environment is 100% on VMware with 3 hosts using Dell Compellent storage. I have 2 Virtual servers acting as sessions brokers and gateways, one of these servers is a licensing server and I had 12, session hosts. All servers are 2012r2 and were about a month behind on updates when this started around March 6th.  I shut down my VMs on the 10th when adding a storage expansion to the environment. After the system came back up this issue hit hard starting right on the 11th.

I am having an issue with the 2012 R2 Session hosts in my environment logging users out and I am not sure why. I have a primary RDS collection and a single server we use for various IT functions acting as its own license server, Session broker and host. Both the primary RDS collection and this IT server both log out users at what appears to be random. When I look in the logs of the Hosts, they show the logoffs as normal events with the reason being 12. I have confirmed the sessions timeouts are set appropriately both in GPO and in the session settings of the collection. These log outs happen if a user connects through the session broker or directly to the server via a console connection as an administrator. I have removed all nonessential GPOs from the servers. The only GPO settings being sent to the servers are a registry key for a database connection, 2 simple scripts to audit and add log on and logoff times to a notepad, loopback set to replace, and a policy adding websites to the trusted sites and allowed pop-ups. I have confirmed these are the only settings for both the user and computer GPO using gpresult. 

This log off event happens for users and administrators. while testing I will log my account into each server and monitor so I can view logs when I get the long off the event. The logs as far as I can tell look the same as if I were to hit the log off button in the start menu. Sometimes I will get logged off of just one server, or sometimes 2 or 3 at the same time(confirmed by logs down to the second) which tells me something is causing this event. 

Since the issue has started I have removed the expansion cabinet, updated all sessions hosts to current windows updates and added two more hosts for a total of 14. I have removed all nonessential GPOs, double checked and set session timeouts in both the collection session settings and GPO, Attempted to set keep alive in RDS GPO settings to 1. I have around 15-20 users using 1 remote app on these hosts during daytime business hours. 

My hope is to get some assistance with diagnosing a possible issue with the server itself, or helping figure out within logs what may be initiating the log of events.

I have not posted any logs because with everything I have looked through this week, I am not sure what is relevant to a trained eye. I can answer any questions and produce logs to anyone who may be able to assist with this issue.

Dear Support, 

RDS CAL is “concurrent session” model or “per user” model? 

Which will release the license usage after user logoff the terminal server or how can we release the old user RDS CAL? 

Could it release the RDS session when the user log off the Terminal Server?

Thanks!

Best Regards, 

Daniel

Hi,

I'm running Remote Desktop for my users and publishing the full Desktop using Collections with 2 Remote Desktop Session Hosts.

I have 2 users who are external consultants and I don't want to give them full Desktops, but rather a share to a specific folder.

My questions are:

1. Is there a way to publish a network share so that the 2 external consultants can access?If yes, how?
2. If the answer is yes, will publishing the network share unpublish the full Remote Desktop?


Kind Regards

Diagnoser shows Host Server Version Server 2016 When Running 2019

When I originally Activated the server licensing via Licenses Wizard using our schools Enrollment ID I may have used an older Enrollment ID number.

I think maybe that was the issue. All I know is when I when into the RD licensing Diagnoser it showed that the Remote Desktop Version Host Server Version is:  Windows Server 2016.

... AND I AM RUNNING WINDOWS 2019 ...

After trying everything i know DE-activating, then re-activating with a more current Enrollment ID for our high school. Did not change anything.

So, removed ALL the remote desktop services and then reinstalled and reactivated. Still did nothing to change the information in the Diagnoser.

The information still shows in the Diagnoser:  Windows Server 2016

HOW CAN I GET RID OF THIS PROBLEM? 

Thanks,

Dave

Migrating a Session Host to a different RDS deployment

March 7, 2019, 7:20 am

Hi guys,

Currently we have two RDS deployments, which we use for RemoteApp purposes 1 deployment consists of:

- 1 single server with RD web, RDCB and Session Host role. (this was configured long time ago)

Other deployment is:

- HA deployment with 2 web, 2 rdbc, 6 session host and 2 licensing servers. No RD gateways involved.

I want to migrate the single RDS server to our HA deployment. So the connectionbroker and Web Acces roles will become obsolete.

Is there a specific way to do this? Or do I need to delete all roles, and add the server from the other deployment as a session host? (apart from all the firewall rules ofc)

Thanks!
