Hello Team,

I have the below issue:

Here is my RDS environment:

I have only one server 2012 R2 standard with the below roles installed 

  • RD connection broker,
  • RDSH,
  • RD Licensing and
  • RD web access

I have published few remote apps and I was able to access them using RD web feed till yesterday. 

Example :https://contoso.com/RDWeb/Feed/webfeed.aspx

I do have installed the SSL certificate on my server and provided the same to RD web. 

But today while I use the same url to access the remote apps I get the below error message 

"The remote computer cannot be authenticated due to problems with its security certificate. security certificate problems might indicate an attempt to fool you or intercept any data you send to the remote computer"

Error code - 0x80072f8f,0x20

Now I can only access the remote apps through RD web access ( https://FQDN/RDWeb)

Please help me in fixing this issue. 

Any help would be much appreciated.

Thanks

SM

I VPN to a website's server menu via CITRIX which has a RDP ICON, it works most of the time, but sometimes when I click

April 30, 2019, 10:08 pm

on the RDP icon, when the launch ica brings up the Citrix popup window, it does a Welcome & disappears.  Usually, the Citrix popup window will have Welcome, and a bunch of messages, then preparing desktop msg & the RDP window pops up to enter the IP address to my remote computer. I try many times with the same results...then sometimes it goes all the way to the RDP popup. What could cause this intermittent problem? There are other application ICONs that also launch ICA successfully like EXTRA Tn3270on their menu. Only the RDP does this. And then the next day, it is fine.

Remote Desktop Services - Windows 2016 - Printer Redirection Stops Working

April 30, 2019, 5:35 am

We have setup many Remote Desktop Services and Users who connect get their local printers redirected. Recently on a Windows 2016 Standard Remote Desktop Server Users find that after some days of working fine they login and no redirected printers are available. If we log into the Remote Desktop Server our printers are not redirected either. The only way we seem to be able to resolve the redirection is to restart the Remote Desktop Server. This is a pain because it is constantly in use until late in the day. Have never had this issue before on Windows 2012 R2 or previous Windows versions. Can anyone find a solution to stop this from happening?

RDS ISAPI Filters

Hi,

I tried to install .net 1.1 on our Server 2016 RDP server, however it mucked up the ISAPI filters on IIS, so it was not working.

I have removed the one with the extra \ in it and recreated the default x86 and x84 ones, how do I know they are working though, and are they even used for our Remote Desktop Gateway?

Everything seems to be up and running by the way.

Windows Server 2016 Remote App Loses focus

February 26, 2018, 3:34 am

I published two RemoteApp from Windows Server 2016.

Upon some action these apps loses the focus and other windows become active in the foreground: very annoying.

The only workaround I found at present is to keep all other windows minimized.

Both apps are "legacy apps" partially developed with Visual Basic that use legacy custom controls, I suppose.

I searched online resolutions but all methods seems related to previous version of Windows server, not fully patched.

The clients are Windows 10 Professional v1709. Both server and client are fully patched

What I tried, without success:

- several app compatibility modes

- the well-known registry tweak on client

- using two old version of mstsc.exe and mstscax.dll

Any help appreciated.

Hello,

Is there any documented approach to minimize the number of running VDIs?

I'd like to :

  1. Schedule starting the machines early in the morning.
  2. Schedule shutting down the machine after working hours.
  3. Allow the users to start their machine without admin support.

1 and 2 are easy, my concern is with 3. or any other recommended approach.

Thanks

Windows 2016 RADC URL rejects credentials. An Error has Occured.

Good Morning,

Hoping to get some insight on troubleshooting this.

I have a brand new single instance Windows 2016 Standard Remote Application and Desktop Server.

The server hosts the following roles;

Gateway
Licensing
Connection Broker
Web Access

The server is protected via a public CA Cert and works as far as being a Gateway, and Web Access is concerned.  Users can connect thru it to other servers via gateway and can open and launch applications via the Web page.

When users try the add the URL https://servername/RDWeb/Feed/Webfeed.aspx  in the RADC applet in control panel,  they receive an error that they are using Incorrect Credentials.  When they type in their credentials in either DomainName\username or username@domainname format it errors out and they need to try again or cancel.

I have looked in the event log in the server and while I can see the transactions happening in the IIS logs,  the end user never is allowed to log in or receives apps.

Could use some insights here?

If I type the URL correctly in a web browser,  I receive a login prompt which once submitted provides me what appears to be an encrypted token.

Azure RDS HTML5 Web Client Unable to Access Gateway

May 3, 2019, 3:49 pm

We have a RDS (Remote Desktop Services) deployment, and recently went through the process of installing the HTML5 web client as per the directions at:

https://docs.microsoft.com/en-us/windows-server/remote/remote-desktop-services/clients/remote-desktop-web-client-admin

Our deployment is hosted on domain A, which has an active directory instance. There is also domain B with its own active directory instance, there is a two way trust between the two.

The problem we are having is that the traditional RD Web Access works fine for all users, but when users from domain B log on to the HTML 5 web client and try to open an app they get a message "We couldn't connect to the gateway because of an error". At the same time the browser console shows the following error:

Connection(ERR): The connection generated an internal exception with disconnect code=GatewayProtocolError(52), extended code=, reason=Gateway tunnel authorization failed with error code=2147965403

During troubleshooting we’ve tried:

  • Verified that required ports are opened.
  • Disabling all firewalls between gateways, brokers, and session hosts – same error.
  • Re-applied the publicly trusted cert to the HTML5 client (via Import-RDWebClientBrokerCert) – same error
  • Verified that the proper cert was bound to the HTML5 client – same error.
  • Enabled NTLM by setting the GPO: Computer Configuration -> Policies -> Windows Settings -> Security Settings -> Local Policies -> Security Options -> Network Security: Restrict NTLM: NTLM Authentication in this domain. To “Disable” (within same domain as RDP) – same error.
  • Ran regsvr32 wksprtps.dll (dll was already registered, but tried it anyway)
  • Verified that the required KB4025334 from July of last year was installed or not necessary (OS was up to date)

Any ideas on other areas we can look at?

Windows Server 2016 RDSH Intermittent BSOD (DRIVER_POWER_STATE_FAILURE)

April 30, 2019, 7:17 am
$

Hi,

Not sure if this should be asked here or not. If I have submitted in error, please let me know and I will redirect my query elsewhere.

We have an RDS platform (single GW/CB/Lic server - Windows Server 2016, 3 RDSH servers - also Windows Server 2016). The platform is accessed using HP Thin Clients via the Gateway's RDWeb feed. The clients connect fine and all applications and hardware devices appear to work correctly.

However, intermittently (doesn't seem to be any rhyme or reason that I can ascertain) one of the servers (it can be any of the three) will BSOD with a bugcheck of 0x0000009f (DRIVER_POWER_STATE_FAILURE). The server automatically reboots after a period of time and then works normally. Sometimes the BSOD happens only once, but then other times it will BSOD three or four times in a row shortly after coming up from the previous BSOD reboot.

From what I can gather, Windows is attempting (and failing) to instruct some device attached to the system (presumably via one of the remote sessions) to enter into a power saving mode and BSODs as a result. I have disabled USB power saving on the server but this does not resolve the issue. I have tested one of the RDSH servers by removing it from the connection pool and left it running without clients for a number of months and it has so far not given me any problems.

I took the MEMORY.DMP file (which is available for anyone to peruse upon request) and tried my best to analyse it using the tools available, and it seems to point to hidusb.sys, though I am unsure as to how to trace the problem any further.

All RDSH servers are patched with latest crticial/security patches as of a week ago.

Any possible thoughts as to avenues I could explore to diagnose/resolve this issue?

Thank you in advance for any advice you might be able to offer.

1.We have installed RDS (RDCB, RDSH, RDWeb) on one host. RDS service is working well without any errors. But if we open Server Manager->RDS we're getting "A Remote Desktop Services deployment does not exist in the server pool.
To create a deployment, run the Add Roles and Features Wizard and select the Remote Desktop Services installation option."

2. We get the same error after Get-RDServer - "The RD Connection Broker server is not available"

3. If we add Roles-> RDS Installation, the next error - "could not retrieve the deployment information from the rd connection broker"

4. If we add this server to Server Manager on another host we receive - "Kerberos Security Issue". All hosts was added to Trusted.

All RDS services are running (including WID). ServerManager and Posh running by Administrator.

How to resolve it?

Dear concern,

I am using 200 RDS Device CALs. I am using 2 RDS server in workgroup environment. I installed RDS host and licensing role in my one server and installed 200 RDS CALs in this server. Also installed RDS host role in another server and map of the first one server as it's licensing server via local policy. Users randomly connect to these two server via Remote Desktop. Licensing server shown the 200 device CAL in console but when user connect to RDS server via thin client (non Microsoft endpoint) they can establish connection only for one hour and got a warning message"There is a problem with your license for Remote Desktop and the session will end in 60 minutes. Contact your system administrator to resolve this issue"then user forcibly disconnected. I had seen two things that RDS server didn't assign temporary license for thin client user and RDS license not count down, it fixed on 200.

Please response me ASAP.

Thanks,

Babu

RDS 2019 - Remote Camera Devices only functional for Administrators

April 27, 2019, 10:08 pm

I have an odd issue whereby I have configured an RDS Collection (1 CB/Gaetweay/RDWeb and 3 RDS Session Hosts) where when a user connects and uses Webcam Redirection, it works perfectly for admins, but non privileged users even though the device is passed through, it doesn't work in any app.

I have used GPO to force enabled the camera redirection feature and force enable the camera for all apps too.

In the Camera settings app, everything is set to On as forced by organisation.

The camera is detected and availible to apps, the Windows Camera Frame Server service starts when the user attempts to load the camera in any app, but nothing is displayed and the camera doesn't kick in.

I have users wanting to use Teams inside the RDS (company policy allows only for company stuff to be inside the RDS) and cannot get them access other than granting Admin rights!

Any ideas?

It seems that I am unable to connect to a computer on my network with the Remote Desktop App (trusted Windows Store App on my Windows Laptop or from the iOS App store on my iPhone), while I am able to connect successfully to it from Remote Desktop Connection (old Windows app).

The remote computer is joined to Azure AD (Windows 10 Pro, up to date; again, this works from the old Remote Desktop Connection application on Windows).

Can anyone tell me if connection to a machine joined to Azure AD is supported on the Remote Desktop App or if there is something I need to do to configure it properly?

Thanks.

Hello

Can a Windows Server 2012 (R2) sessionhost be added to a Windows Server 2019 Gateway, and is this supported?

The Microsoft documentation has not yet been updated for Server 2019.
(https://docs.microsoft.com/en-us/windows-server/remote/remote-desktop-services/rds-supported-config)

I would like to migrate existing SH's to a newer Gateway to make use of a broader set of security ciphers.

Kind Regards

Server: Windows Server 2016 Datacenter with latest updates
Client: Windows 10 Enterprise LTSB with latest updates

Problem: RDP connection from the client to the server takes almost 10 seconds.
The server is multihomed, interface 1 is 10.0.1.0/24 and interface 2 is 211.189.110.45/24.
The client has interface 211.189.110.200/24.
Interface 1 has a higher priority. Whole AD infrastructure is in 10.0.1.0/24.

No errors/warnings in Application or System event log.

But there are errors in Applications and Services Logs-> Microsoft -> Windows -> RemoteDesktopServices-RdpCoreTS

The network characteristics detection function has been disabled because of Reason Code: 2(Server Configuration)..
'Failed GetConnectionProperty' in CUMRDPConnection::QueryProperty at 2735 err=[0x80004001]
'Connection doesn't support logon error redirector' in CUMRDPConnection::GetLogonErrorRedirector at 4073 err=[0x80004001]
'Failed CreateVirtualChannel call on this Connections Stack' in CUMRDPConnection::CreateVirtualChannel at 2349 err=[0xd0000001]

Interface 2 which faces to the internet has enabled only these features:
- IPv4
- IPv6

But it did not work with all features enabled (as they're by default).
