Constant disconnects cause RDP to be almost unusable

February 6, 2018, 11:29 am

I have a user that uses his Windows 10 laptop to connect to the Windows 2008 R2 server using remote desktop. He was working fine for a while then all of a sudden started getting kicked off. He will connect for about 5 - 10 minutes and then get disconnected.

Event logs on the laptop are:

Event ID 1026 - RDP Client ActiveX has been disconnected (Reason = 516) - Remote Desktop can’t connect to the remote computer for one of these reasons:  1) Remote access to the server is not enabled 2) The remote computer is turned off 3) The remote computer is not available on the network  Make sure the remote computer is turned on and connected to the network, and that remote access is enabled.

But he is able to connect so we know that remote access is enabled, the remote computer is not turned off (it's the main file server - never off), and the remote computer is available on the network or he would have never connected to get disconnected.

Event ID 226 - RDP Client_TCP: An error was encountered when transitioning from TcpStateConnectingTransport to TcpStateDisconnected in response to TcpEventConnectionTimeout (Error code:0X80004004)

We only use IPv4 so we have IPv6 unchecked. We specify the IP address and DNS settings so they are on the same network as the server. He remains connected to the network, just not to the server.

Event ID 1105 - The multi-transport connection has been disconnected.

I found an article with similar errors that pointed to inactive ports as the culprit. I checked the registry and found there were over 500 inactive ports. I ran the "fix-it" and it deleted all of the inactive ports. I will apply the HotFix tonight while everyone is logged off and am able to let it reboot. However, clearing those ports didn't stop him from disconnecting.

The event logs on the server are:

Event 25, TerminalServices-LocalSessionmanager - 1:47:14pm

Remote Desktop Services: Session reconnection succeeded: 

User: ServerName\UserName

Session ID: 3

Source Network Address: Laptop's IP Address

Event 24, TerminalServices-LocalSessionManager - 1:52:20pm

Remote Desktop Services: Session has been disconnected: 

User: ServerName\UserName

Session ID: 3

Source Network Address: Laptop's IP Address

This will continue like this all day. He can't stay connected for no more than 20 minutes. Some sessions are only a couple minutes. Does anyone know what we need to do to fix this?

Thanks,

Jessica

Hi All,

I have a remote desktop deployment which consists of RD Connection Broker, RD Gateway, and RD Services or Terminal servers, all run on Windows Server 2012 R2

The deployment works well, access is granted via an AD groups

My question is if its possible to restrict access to these groups to the RDS deployment via an IP address or a range of IP addresses, NPS is installed on the Gateway but i don't seem to be able to get the right settings for this to work, are their any guidelines for this?

Thanks

Redirect USB scale through RDP

We have a machine that is running our shipping software with a scale. The software goes out to a SQL server and pulls some data. This makes the application run very slow as the node is distant from the SQL server.

To get around this, we are running the application through an RDP window on the RDS server (which is on the same rack). However, now the scale that is hooked to the local machine doesn't populate the weight in the shipping application.

so far I have tried:

1. Making sure "ports and other plugnplay" devices is checked in the RDP session setup.

Any other ideas on this?

RDP connection rejects credentials, stays connected and allows login with same credentials

I have a Windows server 2012 R2 running on a VMWare ESXI server.  We have RDP users that are logging in and when they connect with their credentials, it defaults to a message with "Other User" and "Login Credentials Invalid" it is still in the RDP session with username field filled, we enter same password again and it allows login.  This happened after the most recent Windows Updates on Friday 8/17/18.  This is happening to all the users without fail on the first logon with same credentials. Have tried resetting to new password, have tried rebuilding profiles, still is prompting to re-enter credentials to login.  Any help would be appreciated.

Hi,

I have a built an RDS farm in a domain using .local for the server hosts, I have a wildcard certificate that resolves to rdsserverfarm.com. 

Can I use the wildcard cert for all servers within deployment properties and rename the connection broker to match? 

What is the best method for this type of deployment?

Thanks

RDS server - The display settings can't be changed from a remote session

Hi guys, 

I have a virtual server based on Windows Server 2016 Standard that serves as a  Remote desktop Services server.

Users who connect to it via RDC client need to change scaling of size of text, apps and other items from recommended 100% to 125%.

However, these settings are not available even for accounts with administrator's privileges. 

Is there any workaround for this issue?

Software restriction policy bug in Windows 2016

August 27, 2018, 2:35 am

I have the following software restriction policy

- Security level : "disallowed"

- Exceptions: 

%HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\ProgramFilesDir (x86)%

%HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\ProgramFilesDir%

%programFiles%

%programFiles(x86)%

So far so good for ; users can launch all installed programs and nothing else. (I don't remember why I had to add (%programFiles% and %programFiles(x86)% though. The first two were there by default).

Now, testing the same policy on W2016, there's a problem when clicking a link in Thunderbird. That should launch the default browser (Say, IE or Firefox), but the program is denied (a seen in Event Viewer).

One additional weird thing is that Thunderbird says "this file does not have a program associated...". It's not the the usual popup "Your system administrator has blocked this program..." and I was misled in a Thunderbird issue. Which is not.

I had to add explicitly "c:\program files (x86)" and "c:\program files" as workaround.

Hi

I have built a simple RDS Server 2016 environment x1 Server hosting RDS gateway/Web Access & Connection broker x1 Server RDS Session Host.

Internally the setup works without issue but I want to publish this via Azure Application Proxy.

I have followed the process in this link https://github.com/Microsoft/azure-docs/blob/master/articles/active-directory/application-proxy-publish-remote-desktop.md

I can log into the RDS Web Access fine but when I try to launch RDP session I get "Login Attempt Failed"

I've checked IIS and there is no HTTP redirect and rpc is enabled for Windows Authentication.

both RDweb & RPC are published on the application proxy. 

Can any give advice or troubleshooting steps?

Thanks,

Gareth

Issues with HTML 5/Web Cient

I'm experiencing an issue that I believe is being caused by the new web client, but I cannot say for certain. Users who attempt to use the web client get stuck at the following step in the login process:



Sometimes they will continue through to a desktop, some users don't get stuck at all, and some will finally see this message:

The same user can connect to the same collection using any other client (Windows Store, iOS, Android, MSTSC, etc.) without any issues. Furthermore, we use LoginPI to monitor the environment (which uses MSTSC for the connection) and it has not experienced a single connection failure. In addition, I can't find any unusual errors in the event logs on the RDS servers that seem to match the connection errors as I would usually expect.

Is there a log I can look at that is generated by the web client or some troubleshooting I can perform? I am in the process of opening a case with MS Premier Tier 3 support (a process I loathe by the way), but I was hoping someone here could help sooner.

Thanks for the help as always!

rdp not connecting after power loss, clientactivexcore id 1026 reason 3846

hello folks,

today one of our branch offices had a power loss after a big lightning hit, all clients except one could reconnect to the central 2016 ts server and take up their work again, so i can eliminate network components such switch or firewall, vpn etc as source of failure.

also i am able to connect with this clients credentials from the central to the ts it can not be the server itself or the users profile nor its account.

yet i am unable to connect the rdp session from another local account on that particular machine, what eliminates the local users profile also.

what is left is just the win 10 client itself and the striking lightning - curious right?

what is written in the clients eventlog are just some informations, no related warnings, errors nor criticals - same on server side (yet it says client auth succeeded and then its silent)

on the client side the last information entry is as stated in the topic title and the reason code is undocumented (again). i only found a table that tells about 3847 and 3848 being related to expired password and general account troubles. but as mentioned before, the rdp session can be opened from other client, but not other local accounts.

anyone seen that in the wild? any advice?

today i tried about fifty (literally) hints from all over the web from a few hundred sites, without effort. its tiring and frustrating... (other network services still work between particular server and client, such as share access)

kind regards :(

No Internet for End Devices - Long InitialTimeouts/Delays (CRL Check is disabled via IE)

June 19, 2018, 9:13 am
$

We have a 2016 RDS environment where the end workstations do not have any internet access.   When accessing RDweb and launching an app, you will see an initial remoteapp launch timeout of about 90-120 seconds. Any subsequent launches after that work fine with the expected few seconds delay.   After the machine is rebooted we see this issue present again,only for the initial launch.

We've disabled the CRL check via IE and that still doesnt fix the remoteapp launch delay/timeout issue.  From a ProcMan trace you can see its making an is internet alive check to www.microsoft.com and another CRL check to the registry, but what that specific CRL check is to, and what exactly its trying to accomplish i do not know.  

If you allow internet to the end device, the delay does not happen.  

Looking for any pointers as to what is causing this initial launch delay and how it might be resolved?  It appears to be more than the IE advanced setting CRL check, as we have that disabled.

We've also opened a ticket via MS but have not had stellar responses thus far.

Thanks!

windows server 2016 Remote Desktop Services session collection disappeared

We have two RDP servers running our ERP application runs as a published app. Server RS1 acts as the connection broker and is also where the RD Session Collection is normally seen

The RD Session Collection for our published app keeps disappearing. It will be visible under collections for days or weeks, then it will disappear for days or weeks. Then it will show up again. What are some of the possible causes to this and how can I get it back and make it stay.
Currently, the collection is missing. However, if I use the Powershell command Get-RdSessionCollection it returns the collection name.
If I look in Server Manager, RS1 and RS2 show up under Servers. Collections is blank. Only RS2 shows up under Host Servers

(My company upgraded our servers 5 months ago to windows server 2016. (new DC server, SQL server and 2 RDP servers) Our ERP application runs as a published app that we access through an RDP connection.)

SERVER 2012 R2 - LOGGING OFF TAKING FOREVER!

Hi, 

Wondered if someone could please help/advise.

We have 3 VM Servers. When users are logging off one of them it says 'signing out' and take around 10 - 15mins?

We do have roaming profiles going on between the 3 servers however it only happens on this particular one. 

Also when we sign out as the administrator we still get the issue which suggests it has nothing to do with roaming profiles.

Help??
