RemoteApps connect but wont launch after certificate renewal

March 25, 2020, 7:22 am

*EDITED AS INITIAL INVESTIGATION WAS WRONG*

Windows Server 2016 standard - AD Environment - Clients are working from home

RemoteApps worked fine for a while; then we had to create a new certificate because it expired (used for RD connection Broker, RD Web Access, RD Gateway).

Certificate is installed on local machine, put into trusted root.

On some of my clients machines; the remoteapps will connect; but the app wont launch! (Then the client get disconnected after a few seconds.) They are machines were it worked great before the new certificate.

Here are some tests / investigation I did :

  • Not related to Windows edition (happened on a Win 7 pro, Win10 enterprise and some Win10 home)
  • Not related to AD profil the user uses to connect (Profiles work on a computer that doesnt have this problem; and every AD profiles will do the same on computer affected by the problem)
  • Does not seem to be network related (my own personnal PC has the same issue at my home; but my laptop works fine on my same network. NOTE : My laptop is not on their AD)
  • FOR ALL : the remoteapps says it connected to the Gateway; but the app won't launch. (I see the user poping-up on the server; then they get disconnected almost instantly.
  • FOR ALL : If I start their application before on a computer not affected by the problem; they CAN connected and see the app. Moreover; all additionnal apps will launch (from different rdp files)
  • FOR ALL : They were able to connect ONCE without problem; then the problem appeared.
  • I tried clearing the "cache" in HKEY_CURRENT_USER\Software\Microsoft\Terminal Server Client\Default. But the problem persist.
  • In one case (my personnal PC who had the problem); creating a new local Windows profile solved this issue. It didn't on 2 other PC I tried.

This has me racking my brain...

Thanks

(Sorry for original title who was wrong)

RemoteApp Launch Timeout

March 27, 2020, 7:45 am

Hello all,

We've been having an issue lately with a specific app we use over RemoteApp - it's essentially a program built inside of FileMaker.
When people launch the RemoteApp, the FileMaker client can sometimes take 10-15 seconds before it actually shows any GUI (but the process launches immediately). When running as a full Remote Session, or directly on the server, this is no problem. However, it seems when that GUI doesn't show fast enough, the RemoteApp Connection Times out (The icon in the System Tray that shows we're connected to a Remote App Session disappears as well). If they relaunch the RemoteApp (via the RDP file), the process is already running since the user session was just disconnected and not logged off, and the app is fine.

It's not really too much of an issue, but obviously it does cause some frustration with users. I've been searching for an answer, but I can't seem to find one. Is there a configurable timeout for the RemoteApps that I can set?

This is in a Domain Environment.
All the client machines are running Windows 10 Pro. Servers are running 2016 Standard in a Hyper-V environment.
The app is FileMaker Pro 17 Advanced.

Any thoughts?

RDS Collection - The Connection Cannot Be Completed Because The Remote Server That You Reached is Not The One You Specificed

I have deployed a pretty simple RDS farm:

Server A hosts the RD Connection Broker, Gateway, License Server, and Web Access

Servers B, C, and D host the Sessions

After installing the roles, I have created a Collection and put Servers B, C, and D in them.  As soon as I add them, if I try to RDP to Servers B or D, I get an error:

The connection cannot be completed because the remote computer that was reached is not the one you specified.  This could be caused by an outdated entry in the DNS cache.  Try using the IP address of the computer instead of the name.

If I use the IP, it redirects me to the Server C which is already working.  If I try to use my Hyper-V console, it launches and then closes out.  Is this expected behavior?  As soon as I remove the Collection, I can RDP to the servers in a typical fashion.  Please advise.  Thanks.

Hello,

I have 3 standalone licensing servers in my environment, no RDS deployment.

All three of them are Windows 2016.

On all of them, the Remote Desktop Licensing service keeps crashing since 2 weeks or so.

Here is what i get in the Application log:

Faulting application name: svchost.exe_TermServLicensing, version: 10.0.14393.0, time stamp: 0x57899b1c

I did check with sfc /scannow and Dism /Online /Cleanup-Image /ScanHealth on all the servers, no issues found.

Also checked with Infosec team regarding any policy update on the antivirus and file audit, no changes there.

No windows patches have been installed in that time period as well.

What else can i check?

Thanks in advance!

Windows 2003 - Terminal Server Licensing Question

Hello All -

Sadly, I have a client (for reasons I wont bore you with) still using Windows 2003 Standard R2 with Terminal Server.  Since everyone has been working remotely, they have run into an issue.  There are no per device cals left.

From what I've read, revoking a Windows 2003 terminal server CAL is not an option in Windows 2003.    There are quite a few device cals which are being held up because the device is no longer in use, but the license is not close to expiring.

I am working with a Microsoft partner on adding licenses, but in the meantime I was wondering if anyone had any suggestions?

I was also curious what would happen if I deactivated the terminal server and reactivated it? Would all of the licenses become available and assigned as needed by devices actually in use?  Would I need the license keys to reactivate the server with the licenses already on the server?

Thanks in advance.

Azure screen on second monitor will not expand using HDMI - DVI cable

Hi all,

Because of the whole corona home office setup for two I have to connect a second monitor to my laptop with an HDMI to DVI cable (the second monitor only has the DVI portal). Now I'm experiencing problems when I want to expand the Azure remote desktop screen on to both monitors. It just will not detect the second screen... With 2 regular HDMI monitors there is no problem and Azure can be expanded on the two monitors. Somehow the HDMI - DVI cable disrupts this workflow.

Anyone here that has a solution to this problem?

Thanks!

Upgrading RD Services to 2019

I am getting the following error when I try to upgrade an RD Virtualization Host from 2016 to 2019.  this is from the Scanresults.xml

Id="RdsUpgCheck.dll_RdsUpgradeComplianceCheck"><CompatibilityInfo BlockingType="Hard"/><Message Text="You have the Remote Desktop Virtualization Host (RDVH) role installed on this server. After you upgrade, you won’t be able to add the RemoteFX 3D video adapter to virtual machines."/><Action Name="Dismiss"

Google does not return much on this error.  I am doing it this way because it will not allow us to add a 2019 RD Virtualiztion Host to our deployment and I can find to useful errors in the event logs. 

We are trying to upgrade our RD Services from 2012 R2  to 2019. Specifically we are migrating our of RD Virtualization hosts to new hardware on Windows 2019. We have already upgrade the RD Broker to 2019, the RD Web and Gateway are on 2016. 

The upgrade procedure was falling so I loaded Windows 2016 on the RD Virtualization hosts and was able to successfully add the host to our current RD Broker. I then thought I would in-place-upgrade the RD Virtualization host to 2019 but if fails the checks with the error above.

HELLO,

I AM CURRENTLY IN ISOLATION DUE TO COVID19 AFTER RETURNING FROM OS. I AM AT HOME, USING AN IMAC WITH A LOCAL CANON TR8560 AIRPRINT PRINTER. THE SERVER I AM CONNECTED TO AT MY OFFICE IS USING WINDOWS SERVER 2008. I AM UNABLE TO PRINT TO MY LOCAL PRINTER USING THIS CONNECTION. PREVIOUSLY THE OFFICE WAS USING A VMWARE HORIZON CLIENT TO ESTABLISH A VPN AND ALL PRINTER SERVICES WERE AVAILABLE AT THAT STAGE.

User Profile Disks: Disk has the same disk identifiers as one or more disks connected to the system

Hello,

we have a Windows Server 2016 RDS session-based server with User Profile Disks enabled. If there is at least one user logged in, for every other user that connects to the server, a warning is added to the Event logs: "Disk <x> the same disk identifiers as one or more disks connected to the system". Aside from that, all seems to work fine, so should I be worried about these warnings?

RDS CALs won't Activate

I have Server 2016 Standard with 1 RDS CAL installed and all is working.

I am now having an issue when trying to add 3 additional RDS CALs
I have tried to activate by phone and internet and both are unsuccessful.
It says to check the event logs for more info, but I can’t find any error entries. The activation wizard returns this error code Message Number: 0x13a6 (tried to google without success)

I’m not sure if the issue is due to the CALs being issued for Server 2019 (my Microsoft Partner said they were backwards compatible).

Should RDS NPS servers be in DMZ or LAN when you have an RODC?

Hi All,

We have a domain joined RDS gateway server in our DMZ using an RODC for LDAP/AD connections.  In this scenario, is it best to put an Azure MFA NPS server in the DMZ or LAN?  Currently we have it in the DMZ (working fine), as the network team have said the fewer open ports between the DMZ and LAN the better.

I'm just wondering if there's any reason to move it into the LAN?

Thanks!!

Updating Expired Passwords on Wyse 3040 ThinOS 8.6_206

We have a number of Wyse 3040's running ThinOS 8.6_206.

The users of these devices are reporting that once their password has expired, they are then not able to update the password without resorting to calling the helpdesk for help.

Researching this I found a number of threads that suggested disabling NLA.
Is this my only option? If at all possible I would rather not disable security features to enable this.

I also noted some references to using RD WebAccess to redirect to the password reset website. Though my understanding of this is that it would only work whilst connecting from a full OS with a proper web browser. Am I understanding this correctly?

I will certainly be trying to manage this from the user side as well... But at the same time would like a technical fix if at all possible.

Any insight into this would be greatly appreciated.

How can I force a RemoteApp file to request credentials when launched?

I have an .rdp file that I use to launch a remote app.  I entered credentials for one account and launched it.  Then closed it.  Now I need to launch it with a different account.  But when I dble-cick the file, it launches with the prior credentials and doesn't ask me for any.  How can I force it to ask me for credentials?  I went to Control Panel\User Accounts\Credential Manager and don't see an entry in there for my RemoteApp, so I can't delete them there.

Thoughts?

I plan to install a server as remote desktop terminal for 5 users (instead of using 1 pc desktop for each user for their remote desktop terminal). I plan to buy HPE ML30G10 and Windows 2019 standard edition. What license do I need for 5 concurrent remote desktop connections? Can I configure the server as workgroup? I'm confused with the many Windows licensing schemes.

Best practice in Publishing all in one RDSH/Terminal server roles to the internet for remote workers?

Hi All People,

I have deployed the new Windows Server Terminal Server across 5 of my data centre location to support remote workers.
https://docs.microsoft.com/en-us/windows-server/remote/remote-desktop-services/rds-deploy-infrastructure

Image may be NSFW.
Clik here to view.

The above is one of the server configurations that is deployed in my internal network and then access via the browser: 
https://RDSH-VM01.domain.com/RDWeb/
https://RDSH-VM02.domain.com/RDWeb/ 
...
up to https://RDSH-VM05.domain.com/RDWeb/

Can anyone please confirm if the above is secure and can be deployed since there is no Best practice documentation to follow?

If not what is the suggested ways to deploy to allow secure remote users to login while minimizing the cost and server deployment?
Thank you in advance.
