RemoteApp and Desktop Connections update returns Error code: 0x80070003

I had RemoteApp and Desktop Connections working in Windows 7, but it recently started returning the following event log error.
An error occurred. Contact your workplace administrator for assistance.
Connection name: My Apps
Connection URL: https://<externalfqdn>/RDWeb/Feed/webfeed.aspx
Error code: 0x80070003, 0x0
How do I troubleshoot this?  When I enter https://<externalfqdn>/RDWeb/Feed/webfeed.aspx, I am prompted for a user name and password.  When I enter the user name and password, a string of characters is returned.  Is there a way to decode these characters?  The only unusual element of my install is that the <externalfqdn> is different than the windows FQDN.  Both point to the same IP address.  I'm not seeing any event log errors on the server.  If I delete the existing RemoteApp connection, recreation of the connection fails and no event is logged on the server OR the client.

How to disable local resources in RDP using policy?

Hi all,

I'm reaching out for help with an issue I have. Some of my end users need to use external, third party RDP servers. I have no control over the configuration of these servers. For security reasons I want to make it impossible for internal resources (such as my end users local drives) to be available in their RDP sessions on these external servers. My end users use thin clients and domain accounts to connect to Win10 sessions on a Citrix farm. They have to connect to the external third party RDP servers from these Win10 sessions.

Does anyone know if this is possible at all and what my options might be? Any solutions I found myself require server side configuration. Any help is much appreciated!

RDS high availability

Dear All,

I have several questions to ask you regarding RDS 2012 R2.

Most of Company tries to implement RDS in cost effective way.
We can deploy RDS two different ways.
1. All RDS roles in same server
2. Can be used one server per role.

I want to know best RDS high available solution.
Several articles on internet describe only one RDS role for failover(Session host or connection broker)

1. But If i install all RDS roles in same server(Connection Broker, Session Host,Licence), How can I use HA?

2. Can I use hyper-v vm as a clone of my Physical RDS server as HA?

3.  Can I use Azure for High available solution of my onprem RDS server

Very much appreciate if you can explain those things and possibility

Can't change RDWeb password for non-admin accounts

I have enabled the password change option for Remote Desktop Web Services in Server 2008 R2 and applied the necessary hotfixes. I can change admin passwords, but am unable to change any user/non-admin passwords. When I do, I get the following error message:

Your new password does not meet the length, complexity, or history requirements of your domain. Try choosing a different new password.

No matter how complex I make the password, it still gives me that error. I understand that I may be able to change the "Password must meet complexity requirements" group policy option, but is that the only way? Even then, why wouldn't a very secure password work for non-admin accounts?

RDP Connection failure with HA RCB, GW and collections..

Hi All

Found an interesting one.  Windows 2012 R2.  Have HA Gateway, Connection Broker, Host and web servers.  ServerA and B are both host and connection brokers.

If my DNS RR entry for the connection brokers happens to return ServerB and the collection only includes ServerA then I get a misleading "The computer cannot connect to the remote computer" from the RDP client.

The other way around its fine.  Essentially ServerB isn't redirecting to ServerA when it should, I get events 1296 and 1306 in the TerminalServices-SessionBroker-Client eventlog on ServerB

   "Remote Desktop Connection Broker Client failed to redirect the user ..... Error: NULL"

   "Remote Desktop Connection Broker Client failed while getting redirection packet from Connection Broker... Error: Element not found"

Any ideas?  Bug?

thanks,

James

We attempted a stress load on our server and found users unable to join. The RDS would blackscreen and drop. It happened after 8 users had joined. The performance also was dropping as each connection stacked and after we saw the Event Viewer had 450+ Critical Error 1000 with dwm.exe dwmcore.dll crashing.

RD Gateway in DMZ on Server 2016: Same as 2008 R2?

January 5, 2017, 9:02 am

This is my first Remote Desktop configuration using Server 2016. Previously, I used a single 2008 R2 terminal server and 2008 R2 gateway server, then published the gateway server through a stand-alone Forefront TMG server in my DMZ. That worked well since it was RDP over HTTPS. I can still do that in Server 2016 if I restrict myself to RDP over HTTPS, but Forefront TMG is discontinued and RDP over UDP won't work through that. So I'm looking at putting the new RD Gateway in the DMZ and that means making AD visible to the DMZ.

I could follow one of three solutions for 2008 R2's RD Gateway: Expose my domain controllers to the RD Gateway in the DMZ, set up a separate domain in the DMZ and establish a forest trust, or provide a read-only domain controller in the DMZ. I haven't uncovered a better solution for Server 2016 yet.

I'm leaning toward building a read-only DC in the DMZ if it comes down to that, but is there a better solution in Server 2016?

My RDS design uses session hosts and not VDI, and there is a single server acting as connection broker and licensing server. There is only a single session host server, but I may need to expose individual desktop PCs because of certain b0rken applications we use, along with some non-domain servers that support RDP for remote administration. I'd like to remove the old 2008 R2 gateway eventually.

Server 2008 R2 Default printer problem

January 5, 2017, 9:46 am

I have 4 Remote Desktop servers. All are running Server 2008 R2 Datacenter. All connections are run by a broker for load balancing. All of the users use Folder redirection for the user profiles. 95% of my users connect through a thin client device and only a handful of users connect using a PC. When the users log in their default printer changes to the local Docuware Printer PS. It doesn't matter what printer you choose when you log out, the Docuware printer is always default when you log back in. We have been using Docuware for several years and only in the last two months has this been happening. At first it was just one or two users. And now it has spread. My first thought was that there was a GPO that was causing the problem. I have looked and I do not have a GPO that is pointing to a printer. Everything for printers is not configured. I have scoured the internet for answers and only find old info about hot fixes and other garbage. All of my servers are patched to the current release. I am at a loss. Any ideas?

RDS 2016 RemoteApp not going correctly fullscreen

Hi all.

Im testing out RDS 2016, so far its been very nice and performance is great.

But im having a wierd issue when trying to run RemoteAPPs in maximized windows (fullscreen)

It sort of looks like the window is in a incorrect placement. The top and leftmost part of the window is sort of moved out 5-6 pixels when running fullscreen. The buttom part of the window is also below the processbar of the workstation im using.

On my client i am running 2560x1440 and im not sure if that is the issue, but it just seems strange.

Have anyone experienced anything similar, and do you have a solution for the issue?

RemoteApp Java Web Start must be launched twice

Greetings,

We have a RemoteApp that we are pushing to end users.  When starting the application for the first time, there is a pause between the initial application loading and the logon window.  The logon window does not appear unless our users run the RDP again, at which point the Java Web App provides them with the original login window, and eventually a second one.

Does anyone know a good way to fix this?  Is there a way to set the launch time or do I need to put the remoteapp in a wrapper of some sort that keeps the window open?

Caching of desktop credentials with Custom Credential Provider - eliminate the dual login problem

January 5, 2017, 12:12 pm
$

We have written our own credential provider and installed it on a Win12r2 server.

Our CP performs an adaptive multi-factor authentication and logs the user in once the multi-factor authentication has been passed. If needed, the user is sent a one-time passcode that they must enter to complete the login. If the multi-factor is passed, there is no need for any additional passcode and the user is automatically logged in with just their ID and Password.

However, when accessing the server via terminal services (MSTSC), even when there is no need for a one-time-passcode, the user is forced to log in a second time, when they have already logged in correctly via the terminal (MSTSC).

I have tried to setup all the "Allow" options for credential delegation using [TERMSRV/* & TERMSRV/*.ourdomain.com] via the Local GPE and also the Win12r2 Domain Controller Default GPO (Local Computer Policy-Computer Configuration-Administrative Templates-System-Credentials Delegation) but this did not allow the caching of the users credentials.

What is the right way to remove the dual login with a Custom Credential Provider?

Unable to Publish apps

Hi Everyone,

I recently stood up a 2012R2 server and setup remote desktop services.  Since this was for testing, I installed all roles on (1) server.  I set it up and published apps needed as of yesterday (1/5/2017).  Today I can no longer publish any apps.  I can modify them or remove them, just cannot add a new one.  When I attempt to publish a new one I get:

The following requirements should be met for the RD Session Host Servers in the collection:

1. You must be an administrator on the RD Session Host Server ( I am Domain Admin, which is added to the local admin group)

2. The RD Session Host server is running. (One server runs all roles and all services show running)

I can still access the RDWeb portal and launch applications. I did find one forum mentioning the need to license Office 2013.  I went and installed my license, but it did not resolve the issue.

No changes were done on this server during the time mentioned.  I also am the only one with access to it.  I do have some event log errors:

1. ID: 20499:  I am assuming this is just Remote desktop trying to map user drives and redirected folders and it is failing.

2. ID 2056: The Remote Desktop Connection Broker server could not enumerate the targets for the provider named NULL from the database.

I have also uninstalled all roles and reinstalled w/ same results.  Although this time when I reinstalled, the default published apps were not there. (notepad, paint, etc).  I must be missing something.  Any ideas would be appreciated.

Hi All,

Very strange issue. 

I have brand new RDS server 2012 R2 without User Profile Disks (UPD) enabled - all excel files are working fine.

Once i enable the UPD some excel files are not opening and the error is "The file is corrupt and cannot be opened". 

If I remove the UPD, the same excel files are opened without a problem. This is with Excel 2013. Tried to reinstall the Office, check the permissions of the UPD location - everything seems fine.

Any suggestions ?

Thanks

Shared User Starting Multiple RDP Connections to Pooled Virtual Desktop Collection

I have setup a Windows 16 (Datacenter Evaluation) test server with Hyper-V and Remote Desktop Services installed. I am using Virtualization Host with a collection of pooled Windows 7 VMs. What I need to be able to do, that I can't right now, is to start multiple sessions from different clients (they will be thin clients eventually), using the same user. Right now when I try it will start the first one, then the next connection will take over the first one. 

Sometimes I can start 2 sessions with the same user but then the third connection takes over one of the first two. I don't know why this happens but it seems to happen most often when starting the first connection from a desktop using the RD Web Access, and the second connection from an RDP file on a thin client.

I do have a connection broker running on the server, and I cannot use RD Session Host.

Problems with connecting to RDP over VPN

January 5, 2017, 11:46 pm

Hello

I'm using Windows server 2012 R2 standard, the server is located on an ESXI 6.0.

I did a migration of SBS2008 to Windows Server 2012 with this manual https://blogs.technet.microsoft.com/canitpro/2014/05/27/step-by-step-active-directory-migration-from-windows-server-2008-r2-to-windows-server-2012-r2/

I'm able to setup a PPTP VPN connection to the new server. I'm able to ping to the new server and to the old server aswell, when I'm connected via VPN. But when I want to go to the shares it doesn't work. (Can't find server on IP address) Also the remote desktop doesn't work via VPN. 

I'm able to connect to the old server via RDP and file shares are reachable. I already disabled firewall and endpoint security, still that doesn't seem to resolve the problem.

[Edit]

I narrowed my problem down to the following:

I tracert to the server over the VPN and i get 2 replies:

Tracing route to 172.16.0.251 over a maximum of 30 hops

  1    26 ms    30 ms    35 ms  RDPSERVER [172.16.0.117]
  2    27 ms    32 ms    33 ms  172.16.0.251

When I try to RDP to .251 it doesn't work over VPN, but when I try to RDP to the .117 it does work. And that is the new RDP server.
In other words it is possible to make a RDP connection to the internal interface (the one I see in Routing and remote access), but it doesn't work to the Ethernet0 (with IP address .251)

RDP to the old server works over VPN. But I think the problem is something with the Routing and Remote Access, but I got no idea how to solve it.

If there are other things you need, just ask

Thanks for the feedback

Kind regards

Create RDP file for thin clients - Unknown publisher

January 6, 2017, 3:16 am

Hello,

I've a question about RDS 2012 R2. I have created a RDS farm with multiple Hosts. My RDS website and Gateway are on the same server and another server is running the Broker. I created a Collection with a Desktop. When I login to the website I can start the Desktop. I got the warning: "a website is trying to start a remote connection. Make sure that you trust the publisher before you connect". The publisher is the name of the certificate. This is normal behaviour.

Now I want to create a RDP file for the thin clients. When I use the RDP file which I got from the website (download) than the RDP file shows a signature. I think when the certificate expires and I renew the certificate, I have to re-create and deploy a new RDP file. This is not what I want. So I edited the RDP file and removed the signature. When I start the RDP file I got "the publisher of this remote connection can't be identified. Do you want to connect anyway?". The publisher: Unknown publisher.

Is it possible to create a RDP file without the signature, but with the result that the publisher is recognized? Or are there any other possibllities to resolve this? I hope my question is clear.

Thanks

Marcel
