kb4516065 and Win2008r2 RDS intermittend delays

September 20, 2019, 2:45 am

Hi,

We'd like to report an issue with kb4516065 on RDS-server 2008r2, as we have found no issue-reports online.

Monthly kb4516065 has been installed last Friday night, without any issues. The update was considered high priority because we are mainly working on a 5-server RDS-Farm based on Win2008r2.

Since the update we've had multiple intermittent delays and stalls of traffic hourly. Both between clients and servers and between servers of the domain itself.

Crossing off all affected systems one-bye-one we eventually removed kb4516065 from one of the servers yesterday (Wednesday). To find the delays diminish drastically from a single user reporting 10 times between 9am and 10am to (after update removal) 1 delay from 4 users between 11am and 5pm.

Yesterday evening we removed the affected update from all RDS-servers, to get communications working reliable again.
We found no WinOS- or VMplatform-logs reporting the symptoms. No timeout errors, no communication errors from firewall or switches.
Also, no visible signs of CPU stress/pauzes in the VM-platform - as the update also holds fixes for CPU-issues.

As stated above, this is more to report the find. Raise awareness.

---
I'd also like to add that we found, Removal of the update makes the servers loose domain handshake.
Servers were reacting like main 'domain' and 'domain.local' are two separate networks. Only 'domain.local' was available, but shares were recognized as being from the other 'domain' (and unavailable). Removing the server from domain, running SFC, and reconnecting with domain seems to be the fastest way to get communication working again.

Best regards,
Danny Bertisen

File copy over RDG slow

Hi all, we have the following setup in our hosted environment:

Server 1 - RDG, Gateway and License

Server 2 - Session host

They are server 2019.

If I RDP into server 1 and do a file transfer, (copy and paste) the speed is decent. for ex 2MB/sec..

If I RDP into server 2, the transfer speed goes down the toilet, like 300-400KB / sec

Connectivity between server 1 and 2 is fine, they are in the same network.

Any idea?

Hello All,

I have configured my RDS 2019 environment and was successful getting it to work with Azure MFA. However this only works if I have the authentication app and I allow push notifications. Is there a way to MFA the HTML5 page so I can require pin notification? 

Thanks,

RDS 2016 Remote Desktop Services is currently busy

September 20, 2019, 10:37 am

I am running a Server 2016 with RDS and it's mainly used for remote apps. Our users are getting the "The task you are trying to do can't be completed because RDS is currently busy" and looking at the task manager, there appears to be a stuck login which I cannot disconnect. When I attempt to end all processes for that stuck user, it still does not go away and I need to reboot the VM which kicks everyone off.

I am running the latest patches but I find that I have to restart the VM at least 3-4 times a week to allow our users to use their remote app when they work from home.

What could be causing this issue?

Broker DB setup issues: Could not add the RD Connection Broker server RDS-BROKER-TEST.domain to the cluster and migrate the existing Windows Internal Database to the SQL Server database.

I type:

Set-RDConnectionBrokerHighAvailability -ConnectionBroker "rds-broker-test.domain" -DatabaseConnectionString "DRIVER={SQL Server Native Client 11.0};SERVER=sql2016svc.domain;Trusted_Connection=Yes;APP=Remote Desktop Services Connection Broker;DATABASE=rds-broker-test" -ClientAccessName app-broker-test.domain

I get the error:

Could not add the RD Connection Broker server RDS-BROKER-TEST.domain to the cluster and migrate the existing
Windows Internal Database to the SQL Server database.
    + CategoryInfo          : NotSpecified: (:) [Write-Error], RDManagementException
    + FullyQualifiedErrorId : SetRdmsHighAvailability,Microsoft.PowerShell.Commands.WriteErrorCommand
    + PSComputerName        : localhost

In the Broker event log I get:

Database migration - Failed: Could not add the RD Connection Broker server RDS-BROKER-TEST.domain to the cluster and migrate the existing Windows Internal Database to the SQL Server database - Event ID 32779

The Remote Desktop Connection Broker server could not be configured in high availability mode.

Error: The parameter is incorrect.  - Event ID 1739

SQL Server is 2016 - Always On Cluster - VM that lives in the same data center.

In SQL Profilter I can watch it creating the database, setting up tables, etc etc - when it errors out the last thing I see is:

ALTER DATABASE [rds-broker-test] SET MULTI_USER (just before this it updates the db version) - so the database server is up and working.

We've given the machine account full SA access to troubleshoot this issue - same problem.

the WID database that is setup on initial setup is fine - and the machine can connect to it internally.

Where does file go when created by one user and deleted by another?

I need to recover a file created by "USER1" on "PC-R" which was deleted by "USER2" on "Terminal Server"

"USER1" scans a file to a folder in her profile on "PC-R" (Windows 7)

"USER2" remotes into "PC-B" (Windows 7), connects to "Terminal Server" (Windows Server 2012), navigates to "USER1" folder on "PC-R", views the file, then deletes it.

Where did it go?

Have looked in:

"USER1" Recycle Bin on "PC-R"

"USER2" Recycle Bin on "PC-R"

"USER2" Recycle Bin on "PC-B"

"USER2" Recycle Bin on "Terminal Server"

"USER1" Recycle Bin on "Terminal Server"

Where else should I look?

Thanks for any help

"Because of an error in data encryption, this session will end"

All of a sudden my Windows 7 x64 computer is unable to connect to random Windows 2008 R2 servers via Remote Desktop.

I can connect to the same servers from other Windows 7 machines.

The only fix I've come across so far is this, except that key doesn't exist on either my machine or on the server(s):

To resolve this issue, follow these steps:

  1. Start Registry Editor.
  2. Locate and then click the following registry subkey:
    HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\TermService\Parameters
  3. Under this registry subkey, delete the following values:
    • Certificate
    • X509 Certificate
    • X509 Certificate ID
  4. Quit Registry Editor, and then restart the server.

Does anyone have any suggestions please as I'm at a total loss what is happening here.

Thanks.

Need a solution for allowing Remote Desktop access for a limited number of users.

September 20, 2019, 9:48 pm

I've been searching and searching but I'm not getting all the pieces together.  Here is what I need to accomplish:

  1. A VM running a modern Windows OS to run a specific application suite.
  2. That VM needs to be able to handle up to 5 concurrent Remote Desktop connection actively using the application mentioned above. (The application suite is designed to be able to handle this.)
  3. Users will be connecting with tablets, laptops and desktops from the local network and from external connections as well.

The application suite runs a database and is normally installed on multiple desktops with one of them being the "master" running the DB.  Maintaining the multiple desktops is less practical compared to one VM that everyone connects to.  I've seen "hack" ways to run multiple remote connections to Windows 10 and such but I'm looking to do this right.  This application suite is going to be used for the foreseeable future and I don't want to hack it together waiting for an update to break the hack.

What I am asking for is help with what I need for this use case.  I'm ok with building multiple servers (in ESXi/VMware) if needed, though I would prefer only one.  I also would really rather use a per user license since the users are regularly changing out the devices they are connecting with.  

I have downloaded and build basic VMs with the eval versions of Server 2019 Essentials and Standard.

USB Drive redirection except local drives

hello every one 

i have a issue with RDP redirection

the problem is i can't redirect just usb drives but not the local drives

i think of some script to run when the rdp session is created on the server and map the usb on the user's computers

but i don't know where to start

i also tried redirection policies in group policy but when you Disable drive redirection it's also assume the usb drive as a drive so i can't use the group policy or other things except some script that map detect the PnP devices on user's computers and map it and prohibit the local drives redirection.

thank you in advance

Hi all,

After the Collection Security settings on Windows Servers 2016 RDS, has been configured to -

Security Layer: RDP Security Layer,

Encryption Level: Client Compatible,

no check on "allow connections only from computer running..."

that changed was made in order to enable users to change their password when expired.

now users have to enter their password twice in order to login,

the GPO is configured with 'Always prompt for password upon connection‘ to disabled.

any ideas ?

thanks a lot!

Disconnecting RDP Session Causing Excel C++ Macro to Pause

August 27, 2019, 8:34 pm

Hi,

I'm kicking off an extensive Excel macro on a network machine via Remote Desktop Connection that takes roughly 50 hours to complete. The macro VB calls a DLL file to execute a chunk of code in C++ (I did not build it and am not well versed).  Running the macro in an active session works fine, but if I disconnect and return a good time later, I can tell the macro has made zero progress since when I disconnected from the session--I can tell from status bar communication in Excel.  Once I reconnect my session, the macro continues running like I'd never left and no error messages or code execution breaks messages to be found.

It gets weirder--I have 4 options of VMs to choose from, all of which have identical specs (Windows 10, 64-bit Office, 64-bit OS).  The macro will continue to run when I'm disconnected on only ONE machine. The only difference I can see on the one machine that's successfully running the macro, is that it's the least recent to have been rebooted (and therefore updated) of the lot.

I do not have local admin rights on any of the machines. Any incite would be greatly appreciated. 

I'll caveat that I'm kind of a layman in tech speak; I apologize if I chose the wrong categories to post on.

dears,

I need your assistance with the below, i was deploying rds server. 

Configured rds hosts and rds brokers and rds licenses servers. I issued from the license server licenses per cal and per devices.

In the collection, i added a group that contains the users who are able to connect to the host.

After testing, more than one user were able to connect to the rds host therefore the testing was successful.

however when i went to test the per device cal, i did the following i added the server from where i want to access the rds host to the collection group created earlier. then i logged in to this device using anonymous user and tried to rdp the rds host from that server, however it returned an error : the connection was denied because the user account is not authorized for remote login which is true, the anonymous user is not added to any rds group but the server from where he tries to access the host is added to the group.

I need to understand the per device scenario, can anyone help me with how it its tested?

best regards

Hello team,

I have a windows 2016 server and I want to add more other RDP sessions.

I know by default, the system has 2 simultaneous sessions and I'm looking to increase the number of sessions by the user and want to purchase another three licenses.



Does it mean I will have 05 simultaneous RDP sessions or the TSE server will not include the default 2 sessions?



Thanks for your support

Enhanced Video Renderer - render failure in RDP session

September 20, 2019, 12:42 pm

Enhanced Video Renderer is used in my application.  It displays fine on Windows 7 thick client.  When this application runs on a Citrix server (Server 2016), EVR will not render at all, if the render window is on monitor 2 (right monitor).

Because Citrix runs on top of Terminal Services, we tried to check over RDP.  See the same symptom over an RDP connection.  Testing EVR capabilities using GraphEdit: EVR will render fine on Monitor 1 but not Monitor 2 (black window appears).  Without RDP, connecting over UltraVNC, there is no problem with EVR rendering on Monitor 2.  Another curious thing, is that if the graph is stopped, and the render window is dragged from one screen to the other, the window will render fine after the graph is restarted, so long as the window is at least 50% on the left monitor.  Seems like a rendering problem as the source filter is definitely not the issue.

Is there some reason for this to fail?  Is there any RDP configuration (or omission) that contributes to this problem.  Many thanks in advance for any knowledge on this.

Replaced SSL cert, now getting certificate error when launching remote apps

Set up:

Server2016 Hyper V Guest 
Remote Desktop Gateway
Remote Desktop Licensing
RD Web Access
RD Connection Broker

Server2016 Hyper V Guest
RD Session host

Internal FQDN: Domain.Company.Local
External FQDN: company.ca

SSL Cert Wildcard: *.company.ca

DNS redirects remote.company.ca > external IP on firewall

Firewall port forwards RDP requests to Remote Desktop Gateway via custom port :9999 (443 was taken and my firewall didn't redirect through a WAF well with RDP so this worked)
Custom Port was set in transport options on remote desktop.

Initial setup worked fine, imported the SSL certs (which are now expired) then I updated the server to the HTML 5 client.

That worked until the certs expired, I replaced the certs first in the remote desktop gateway manager then in the Server Manager > Remote Desktop Gateway Overview > Collection Properties (selected the new cert for each, hit apply)

Checked IIS binding, its now the new cert.  Did IIS reset, and rebooted server to make sure changes took.

The portal gets the new cert just fine back to secure padlock in browser.  When launching an app though I get a certificate error:

Your session ended because an unexpected server authentication certificate was received from the remote PC. Ask your admin or tech support for help.

Certificate information:

Server Name:
CN=*.company.ca
Certificate thumbprint (SHA1):

<THE CORRECT CERTIFICATE THUMBRPINT)

I verified the thumbprint against the cert and all was correct.  I hadn't changed the FQDN from the setup before, and even tried rolling back the server and checking, as soon as I swap the cert out in any of the places it breaks the FQDN external being different from internal hoops I had to jump through originally.

Oddly if I go to /rdweb and use the non-html5 method the remote apps fire up and launch just fine.

What am I missing here?

Black Screen on all new Connections, SessionHost has to be rebooted

hi,

we're suffering from session hosts that produce black screen errors in a RDS 2016 farm.

already connected users can mostly work, all new connections end up with a black screen.

to resolve the error the server has to be restarted.

i can say that

- this error appears after error 1534 (Fehler bei der Profilbenachrichtigung des Ereignisses Delete für Komponente {709E2729-F883-441e-A877-ED3CEFC975E6}. Fehlercode: Das System kann die angegebene Datei nicht finden.) starts appearing in the eventviewer.

- upon checking the registry for this SID i end up at "ProfileNotifyHandler Class app id {E10F6C3A-F1AE-4adc-AA9D-2FE65525666E} inprocserver32, C:\Windows\System32\gameux.dll".

- starting explorer.exe per taskmgr does not open an actual explorer window although the process appears in taskmgr

- tskmgr, eventvwr, cmd can be started without problems

- affected users appear as active in RDS management

- no third party security software is installed

- farm is fully patched

- HKLM\Software\Microsoft\WindowsNT\CurrentVersion\ProfileGUID and ProfileList are ok (no old or .bak entries)

looking forward on how to resolve this without  rebooting the server or a permanent fix

thank you

best regards

Remotedesktopgateway - Configuration issue

Hi everyone,

I have a Win Server 2016 with RD Services on it. Everything is running fine but Remotedesktopgateway cannot be configured by me. I installed the role without errors but configuration ends in the error:

RD Gateway Configuration Failed on [X] With Error: Unable to configure the RD Gateway server: [X] . The error is You cannot call a method on a null-valued expression.. (event-id 4119)

I found no solutions to resolve this issue on the web. I think the problem occurs already during the installation process because the RPC application is missing in the IIS. It's not the first installation of the RDG. Maybe there are some old entries in the registry what cause this failure but I do not know where to search ... Would be nice to get some help from the community ...

Thanks,
Chris
