Lots of lag in RemoteApp when security layer is set to Negotiate or SSL, but not with RDP Security Layer

March 9, 2018, 12:22 pm

We have three (completely separate) terminal servers, all in one boxes with session host, gateway, everything (I know it's not as secure but that's how it is for now). We're publishing some programs using RemoteApp. Users of the apps experience a lot of lag with them, clicking and no response, then it'll catch up, etc. This applies to both 2012 R2 and 2016 term servers.

I've been troubleshooting for a while and finally figured out what seems to be the problem, but I'm not sure what the proper solution is.

In the session collection properties under Security, I discovered if I set the security layer to "RDP Security Layer", it completely resolve the lag issue. 100% fixed. If I set it back to Negotiate or SSL, the lag returns. I've tested it on all three of the terminal servers and it resolves the problem on all of them.

The problem with leaving it set to RDP Security Layer is 1) Not as secure of course, and 2) There is a very long login delay when opening a RemoteApp, as well as it seems the login isn't passed to the server, so the user during the connection has to click the "Show Details" dropdown which shows the actual desktop, login to the remote desktop, THEN the RemoteApp will open up.

I'm at a bit of a loss as to why SSL/TLS would be causing such a big delay. Bandwidth and server/client resources (CPU/RAM/etc) are not an issue here.

Printing doesn't work after disconnect

March 5, 2020, 10:47 am

Hey all,

  I've just deployed a RDP session host for a new customer running Server 2016, through an RD Gateway.  My end users are spread around several states, but all connecting to the same data center.  There are about ~200 users.  They are using RDP to connect to the server.  

  They are using thin clients that are set up to connect to local printers, and those work fine.  When the users connect to the RDGateway host and then their server beyond that, printing works fine, I can print test pages back to their printers and applications print flawlessly using the Remote Desktop Easy Print driver.

  Then, if they experience even the briefest disconnect to the server, printing stops working.  Print jobs enter and disappear into print queues and never print.  No error message that I can find.

  I have tried installing the proprietary drivers and forcing group policy to use those, and printing got worse - some couldn't print at all after that.  After returning back to using the RD Easy Print, we were at least back to just being unable to print after a disconnect.

  The clients range from Windows 7 to Windows 10, but all seem to suffer the same problem.  I've tried searching for results on this issue but I'm not seeing any solutions.

Any ideas?  Anyone?

Thanks,
Dave

RDS 2019 - Unable to connect when screen scaling enabled on Surface Book 2

March 31, 2020, 6:30 am

I am in the process of standing up an RDS 2019 environment along side our RDS 2016 environment. 2016 environment was thrown together in a hurry a couple years ago and I figured this would be a good chance to stand a new one up done halfway properly. No issues on the old environment, what few published RemoteApps are there work ok.

However, on the 2019 environment I seem to have issues connecting with my Surface Book 2.

Scenario:

GW01 - RD Gateway
WEB01 - RD Web
CB01 - RD Broker
LS01 - RD Licensing
SH01 - RD Session Host running Wordpad RemoteApp to test

Client:
Surface Book 2
Windows 10 Enterprise
3000x2000 with 200% scaling
2 x 1920x1080 monitors connected via Surface Dock

This client connected to our RDS 2016 farm does not have any issues running a RemoteApp. If I attempt to run the test Wordpad on the 2019 setup I get the following message:


[Window Title]
RemoteApp Disconnected

[Content]
The configuration of the local display monitors was not accepted by the remote computer. For assistance, contact the owner of the remote computer or your network administrator.

[OK] [Help]

Here are the scenarios I have tried:

On dock with external monitors with W10 scaling at 200%: Fails with error above

Off the dock with no external monitors but native resolution scaled to 200% - works

On the dock with native resolution scaled to 100% - works

The first scenario is going to be the most common use for me. This is really a niche issue at the moment since I am one of a few that are using a Surface device with a high resolution display. However we continue to roll out other Surface devices and laptop brands with high resolution screens so I could see this being more problematic down the line.

I haven't been able to find another reference to this error thru my Google searches so far. As long as scaling is the same across all monitors it appears to work ok but in this mixed scaling setup, the 2019 session host fights back where the 2016 session host appears to handle it with no issue.

Hi, 

I want to move the server 2016 RDS users profile to Server 2019 server. Does anyone know a way to do it without any user interaction?

I have tried the xcopy command but when the user logs on the server assigns a temp profile.

xcopy c:\old c:\new /O /X /E /H /K

Thanks,

Hi

Anyone knows if it is possible to publish an application and force it to open in % of monitor size/resolution?
In Citrix this is possible, but I haven't found anything about this in RDS 2008R2.

Interruptions in RDP connection - at different time intervals - no rules

We have a Windows 2016 RDP server with MS Dynamic NAV client application installed on it. NAV database is on another server (also 2016). Our RDP clients (NAV users) use NAV through this server and we have complaints from them regarding intermitent delays during their work, including RDP short disconnect/connect cycles from time to time. There are just several clients working same time. In their words the problem is present even while they access RDP from local network and through VPN. Also, they say the problem arised about a month ago (maybe from 23 or 24 February). In windows logs I can't find what would be a problems.

Is there anything you could suggest we should try to check with it?

We have another servers, in the same network, we dont have this problem.

Jan 2020 Windows Updates KB4534297 & KB4534309 Break Mac Remote Desktop connections through Web Application Proxy

In a 2012 R2 RDS environment where Web Application Proxy and RD Gateway are used we found thatMac RDP clients could not open RemoteApps after installing the January 2020 Windows Updates KB4534297 & KB4534309.

Mac users were getting errors 0x204 or 0x3000008 when attempting to connect.

Windows RDP clients could connect fine. The main issue was with the previously mentioned updates on the Web Application Proxy server. Uninstalling these updates from the Web Application Proxy server and rebooting allowed Mac connections to again work through Web Application Proxy.

Office 365 Proplus on Windows Server 2019 RDS collection with UPD loses activation on every logoff

March 31, 2020, 9:03 am

Hello

we have a brand new Remote Desktop Services Collection on Windows Server 2019, consisting of 2 RDS Session Hosts and one broker.
We use User Profile Disks.
Office 365 Proplus is installed like it should be on RDS Servers (sharedcomputerlicensing=1).
Users can start Office, and enter their Email and Password to activate O365 Proplus and work with it.


But as soon as a user logs off and on again, O365 says activation is broken, and asks for the password again (this even happens if the user logs off and on to the same Session Host as before.)


We also have exactly the same environment but on Server 2016 instead of 2019, wehre everything works fine.
If we deactivate User Profile Disks on Server 2019, it works fine too, but we need them to use the collection.

We have also used SCLCacheOverride and SCLCacheOverrideDirectory, but this also didn't work.

How can we get O365 ProPlus to remember its activation on 2019 RDS Servers with UPD?
Thank you!

Problem with Windows Server 2019 RDS License

We want to deploy few new rds servers on server 2019 but it seems that the per user licensing is not working correctly if in a workgroup.

Evertime when a user logs in it gets the following message:

'There is a problem with your Remote Desktop license, and your session will be disconnected in 60 minutes, Contact your system administrator to to fix this problem'

In the gpo the license server is specified and the "per user" mode is selected. 

Same issue as :

Event-ID 20491 while user logoff with UPD

Hi,

normaly the event-id 20491 issue should be solve with this update: KB3192404 (Preview of Monthly Rollup)

But we have this problem still. (on Windows 2012 R2 fullfixed)

Addressed issue where the user profile disk (UPD) does not get unmounted when a user logs off. Therefore, users get temporary profiles and are not able to work with their own profiles during their next logon. The Event ID 20491 with a description of“Remote Desktop Services could not disconnect a user disk for the user account with a SID of <SID>. The error code is 0xAA.93 (or error Code: 0x91.38)will be logged

The behavior after event ID 20491 is different for us. Either a temporary profile is created or the profiles are given consecutive names such as <username>.001, <username>.002 and so on.

BUT the effect does not occur every time you log off. There are days/hours when the logoff works including deleting the local userprofile!

Hint: The UPD is stored on a SMB V3.x share. Offline-Cache and other tricky features are disabled on this share.

How can I fix this error?

Thanks for your help!

Danke und liebe Grüße Oliver Richter

Hi 

We have a user that is using the RDS server in azure in a farm. When the user logins with one monitor configured to be used in the mstsc it launches. When selecting use all monitors it shows on the taskbar. However, you can't maximize move it or see it. Is there away to fix this. Also, if you login with the one monitor and launch it then disconnect. Then login with use all monitors it shows. But if you close the app it won't re-open just shows in the taskbar.

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.

Standard users can block all incoming connections

I installed a Windows server 2019 with RDS role.

When I start a RDS session using a simple user with no administrator right, I can change firewall configuration in order to force the server to reject the incoming connections using the new Application (Windows security). This behavior is a regression. It have been introduced in Windows server 2019, Windows server 2016 does not have this issue.

For the moment, we have found some configuration/workaround but not something perfect:

* There is the GPO Hide the Firewall and network protection area but it also remove the right to Administrator
* Remove the users group right on the executable file from C:\Windows\SystemApps\Microsoft.Windows.SecHealthUI_cw5n1h2txyewy but it is more a hack than a customization.

Is there another way to fix this issue per user (registry tuning, user GPO)

The main thing is that non administrator user can break the Windows server 2019 using this new menu.

Thank you for your help

Windows 2003 - Terminal Server Licensing Question

March 28, 2020, 7:13 am

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.

Nick

Remote Desktop Certificate Error: Certificate works on half the environment

Dear all, 

I have a weird issue on my environment. 

In our env there are two basic segmentations -protected and internet facing. 

There are designated RODCs to support the Internet Facing part.

I have deployed a certificate to use with RDP. The certificate works without issues on the protected part and on the RODCs.

On the internet facing servers I get the following error: 

The RD Session Host server cannot install a new template-based certificate to be used for Transport Layer Security (TLS) 1.0\Secure Sockets Layer (SSL) authentication and encryption. The following error occured: The specified domain either does not exist or could not be contacted.

Server then do not use the certificate for RDP. 

This started after a network change but I cannot pinpoint the issue. DC-Client communication looks ok, servers enroll for the certificates with no issues, certificates are installed on servers with no issues, it is just that problem with the RDP usage. 

I have added an extra CDP which is accessible by the internet facing servers, no luck. 

Any ideas would be greatly appreciated :)

Unable to connect to new RDSSH after upgrading to HA Connection Broker

March 31, 2020, 8:56 pm

We have an RDS farm that has been in place and working perfectly for over a year.

Previously there was a Web/Gateway server in our DMZ, single CB/License server, 7 collections and 7 total hosts (1 in each collection).

With the current pandemic going on we are ramping up our RDS capabilities and I updated the CB to be setup in HA.

Since doing this any new hosts I configure and publish will not work.

The new configuration is the same as above but with CB in HA and 1 new collection including 1 host and a previous collection now publishing 3 hosts. 

There were no errors when configuring the new collection & hosts and they are identical to the pre-existing hosts (Server 2016). There are no DNS/DHCP conflicts etc.

When logging into the RDWeb portal any assigned collections are shown as normal and if you select a pre-existing collection the connection goes through as normal and works.

However if I try to connect to the new collection or the collection which now has 3 hosts I get the following error:

----------------------------------------------
Remote Desktop can't find the computer "HACB FQDN". This might mean that  "HACB FQDN" does not belong to the specified network. Verify the computer name and domain that you are trying to connect to.
----------------------------------------------

Once I remove the 2 new hosts from the pre-existing collection I am able to connect as normal again.

I have been trying to troubleshoot this for over a day and have no idea where to look next and I'm hoping one of you fine people will be able to help.

Many thanks in advance for you help.
