Licensing without permanent assignments

July 2, 2018, 10:03 pm

We were running a Windows 2008 RDS server which had licenses just as old.

The licensing server crashed and we had to reinstall onto another server.

Before this, with 50 licenses, any random 50 devices could remote in.

There was no revoking necessary, and it never permanently assigned a license to someone's machine.

It would stop that 51st person from logging in simultaneously, but it didn't permanently assign a license to a machine where someone else couldn't log in for lack of licensing when less than the max were concurrently running.

Now, the first 50 people that have logged in are the only devices that can, and some of those devices are home machines, or personal mobile devices (like android and iPad tablets).

Did we install the licensing server incorrectly to make such a thing occur, or is this the way it is?

We need to be able to allow the number of users that we have licenses for to use remote access, and not simply the first 50 that got the 50 licenses.

Is there a way or type of license that allows this?

Is there a way to shorten the expiration time so that devices we can't control do not get licensing.

It is not possible to control what device a user uses to access remote services without adding other layers to the network that defeat our business requirements.

Any help would be appreciated.

Remote App Blackscreen, RDP works fine

July 2, 2018, 12:50 pm

I have an external user who connects to a remote app via RdWeb. They had no issue until last week and no changes were made on the terminal servers.

THE ISSUE:

When they launch the remote app, the user gets a black screen if you click details. They can RDP to the server fine (using the Connect to another PC tab in IE).

The mstsc.exe process has to be killed via Task Manager. 

Another user in their office is having no issues.

Things I have tried:

1. Had the user with issues try from the PC of the user without issues. Same problem.

2. Had the user connect to 3 instances of this remote app in 3 different collections. 1 uses User Profile disks. 1 does not and sits on the same network as the previous. 1 does not use profile disks and sits in our DMZ. The user can get a successful connection from the server in the DMZ but the speed is an issue. 

3. Looked for a profile disk for the user on the network share and there was none (the user is in our Guest child domain which is not a 2 way trust), there was no profile disk, but there WAS a profile with the username and .backup on the actual terminal server.

4. Deleted the local user profile on the both internal servers and had the user try again. Same result.

5. Had the user RDP to the server and launch the app and it worked without issue. 

I am thinking it is related to the user's terminal server profile because the issue is repeatable from another user's workstation. However, the user is able to RDP to any of the terminal servers and work fine. 

The difference in the server in the DMZ and the internal servers is that the server in the DMZ uses a different encryption/compression policy. The internal policy forces the encryption level to "low", does not use an encryption algorithm and is set to not require NLA. The server in the DMZ was specifically created with a different encryption policy to resolve a previous issue with external users getting a black screen to the internal servers. The internal servers go through a Cisco WAAS in some cases and the internal policy was set to the recommendations for this setup. 

Keep in mind though, that everything worked fine last week and everything still works fine for everyone except this single user.

Any insight or steps for further troubleshooting would be appreciated.

Hi there,

I have setup a client site with a Server 2012 RDS with 5 CALs. They are being hit with the 2 users limit and a third connection is required to 'select a user to disconnect so you can logon'. 5 valid device CALs are installed. Event logs are clear, TS Licence Manager reports 5 CALS are active, any suggestions?

Screenshots attached of the installed licensing server and CALS.

Thank you

Large RDS farm, 10000 users+ considerations

Hi All,

         Fairly experienced at putting in RDS farms for 5-1000 users.

Recently, we have had a client come to us asking for assistance with an RDS farm for 10000+ users.

This post is just on the off chance that someone else out there has deployed an RDS farm of this size (or larger) and can advise if they are (or even better, are not) any pitfalls that only effect farms of this size ?

Hi,

We have a RDS server ( Windows Server 2012 ) connected to a DC controller ( Windows 2016 ) : frequently users can't login because domain can't be reached.

We already pushed the server in the domain again but problem remains, the events logged are

- 36887 schannel

- 1061 : remote desktop session host server was unable to retrieve users licensing information from AD. Error 0x8007054b

- 5719 NETLOGON

After sometime ... adn without changes users can login again.

What could the problem be and how could we solve that ?

Best regards

Best Practice Patching VDI Clones Gold image

December 12, 2017, 3:42 pm

Hi Guys,

I have been trying to find a article that clearly describes best practices  on how to patch VDI Gold images.

Naturally we do not want to have to update the gold image every Tuesday and rebuild all images. 

My understanding is that we just need to patch the Clone images using normal process. EG WSUS and patch deployment program. (We do not have SCCM at the moment.)

This would keep the clone gold images updated. 

We would also need to update the Gold image so that when we rebuild any desktop it would include all the patches. 

If we want to install a new app or change version we would need to update the gold image then rebuild all clone images. 

Can someone confirm this for me, or give me more information?

Thanks for your time.

Disable TLS 1.0 on a FIPS enabled Windows 2012 R2 server

June 29, 2018, 12:34 pm

We are disabling TLS 1.0 per the standard recommendation via keys:

HKLM:\SYSTEM\CurrentControlSet\Control\SecurityProviders\SCHANNEL\Protocols\TLS 1.0\Client

HKLM:\SYSTEM\CurrentControlSet\Control\SecurityProviders\SCHANNEL\Protocols\TLS 1.0\Server


What are seeing is very odd.  On all systems that are not FIPS enabled, RDP (port 3389) is only accepting TLS 1.2 connections (this is per our Nessus scans).  On all systems thatare FIPS enabled, RDP is accepting TLS 1.0-1.2 connections.  



The reg keys are the same.  Is this a known issue with FIPS + RDP + these protocols?  Can someone provide any documentation?



Thanks much

How to connect to different Collections from the same Web Access server?

July 10, 2018, 6:11 pm

I am looking for a way to use a single RD Web Access page to connect to different Collections. Here is what I have.

Session Collection 1 - Application published using farm webapp.domain.com (Five servers)
Session Collection 2 - Remote Desktop published using farm rds01.domain.com (Five servers)
Session Collection 3 - Remote Desktop published using farm rds02.domain.com (Five servers)

Each farm has a different use case and applications, hence the three farms. But I would like users to access any of them by logging into https://web.domain.com/RDWeb.

The farms are using round robin DNS, which could be part of the problem. I did this so if you use mstsc, the computer name points to rds01 which has an A record to all five servers.

The other potential problem could be that I used Set-RDPublishedName on the Connection Broker and changed the name to webapp.domain.com. I did this so the wildcard SSL certificate didn't issue any warnings.

It appears that the published name on the Connection Broker is what the Web Access server uses to launch everything. So instead of Remote Desktop going to RDS01 or RDS02, everything redirects to webapp. If what I am trying to do is possible, what do I need to change?

Memory exhaustion on Win10 Pro via RDP

July 11, 2018, 1:36 am

Hello,

I'm using freerdp to check RDP availability of a Win10 virtual machine running under Proxmox 5.2 (kvm). The command used is:

/usr/bin/xfreerdp /cert-ignore /auth-only /u:$USER /p:$PASS /v:$HOST

Every time this command is launched, the svchost.exe process related to "TermService" grows around 8MB in its "private bytes" memory. That amount is reduced to around 5MB if you set the display size in freerdp to 1x1 (/size:1x1). That memory is never returned to the system and in a few days some messages related to "resource exhaustion" are logged and eventually RDP stops working. At that time, that svchost.exe process has more than 10GB of "private bytes" (VM has 20GB total memory). Win10 needs to be restarted for RDP to work again, as restarting TermServices service does not help.

Adding memory or a bigger pagefile to the VM only delays the time when RDP stops working, it will eventually fail anyway.

I dont know if this is caused by FreeRDP shutting down the connection without notifying the RDP Server properly or if it is a Windows issue or a configuration issue. It's very easy to create a DoS to a Win10 Pro RDP
server if you have valid credentials. I haven't tested any other Windows version nor any other virtualization environment. Luckly, it doesn't happend if you dont have valid credentials.

Please, give it a look to find out what could be causing this behaviour.
Thanks a lot

Issues with RDP after RDS install

Hello hoping someone has a quick answer. I have a 2012 R2 server I installed RDS on. After I installed RDS I attempted to configure a collection. I install the collection with pretty basic settings. I give it a collection name, I add the local server to the server pool ( its the only option) I remove the domain user group and add domain admin to the "User Groups". I unchecked user profile disks because its not required. I then hit create. It does its thing and comes back with the error " Unable to configure the RD Session Host server <SERVER / FQDN> Invalid operation.

When I hit close the collection is there. I have not been further than this to test anything. There is another issue. After I add the RDS role and do this. When I attempt to RDP back to the same server I can no longer RDP. I get an error the server refused the connection. When I remove the RDS role I can remote back to the device.  

I did find this article ( https://support.microsoft.com/en-us/help/3014614/you-cannot-create-a-session-collection-and-an-error-occurs-in-windows ). This did not help.  Any thoughts would be great.

Server 2008 R2 logs off users at login

We have an issue that just started happening today on our standalone Windows Server 2008 R2. There is no domain it's just using local users and groups when a particular user tries to login it goes through the process and then immediately logs them off before the desktop is reached.

The following errors are logged in the event viewer:

Event ID 5: source: Kernel General{Registry Hive Recovered} Registry hive (file): '\??\C:\Users\username\ntuser.dat' was corrupted and it has been recovered. Some data might have been lost. followed by a event id 7002: User Logoff Notification for Customer Experience Improvement Program

If I setup a brand new user they have the same issue, if I then add the existing user or newly created user to the administrator group they can both logon, remove them from the group and they can no longer logon anymore.

I have run a scandisk, sfc /scannow, rebooted the server, disabled customer experience improvement, If I try to run gpedit.msc I get "Administrative templates encountered an error while parsing incorrect document syntax" I get a half dozen of these before it allows me in. I tried to delete the users profiles and copy over another working users ntuser.dat but that doesn't help. All terminal server licensing is correct and working.

Leaving these users as admins is not a solution for obvious reasons, any ideas?

Hi all

In TERMINAL SERVER this alert appears on every user who logs on:

Event ID 20499 "Remote Desktop Services has taken too long to load the user configuration from server \\DC for user username"

After this warning comes:

Event ID: 1296 -- Description: Remote Desktop Connection Broker Client failed while getting redirection packet from Connection Broker.User : domain\username

Error: Remote Desktop Connection Broker is not ready for RPC communication.

Is it something to treat it?

RDS Farm unable to login

July 12, 2018, 5:31 am

I created another collection in my RDS Farm and added a single RDS Host. The idea here is that users will use the desktop of this machine not published apps.

I created the collection using a single security group which I created just for this collection

I then added one user to the security group (they are a member of no other groups except domain users)

I then attempted to remote login through the connection broker and get the following error. 

"The connection was denied because the user account is not authorized for remote login"

It appears that the connection broker is not passing the login through to the session host, but instead treating it as if it wants to login to the connection broker itself. Not sure what I have done wrong here. It clearly says on server manger "Remote Desktop is published for the users of the collection."

Note the user can remote directly to the RDS host and login, but the point is to have it go through the broker as it's IP is the only one available outside the LAN.

Windows Search EDB file very large on Server 2012 R2 RDS

Hello experts. 

We have hundreds of users on 2012 R2 RDS session host servers and have a non-stop problem with the Windows Search .edb file growing extremely large and filling up all disk space. 

This looks to be a major problem for IT departments everywhere, based on a few seconds of searching around. 

The main items we have in place to try and combat this problem:

1.) We have enabled the "DisableSearchBackoff" and added the Corecount registry key found in this post:

http://www.cyberdrain.com/?p=116

2.) We have a batch file that runs the commands found below on a nightly basis, which defragments the search index database. 

https://support.microsoft.com/en-us/kb/2838018

3.) We have moved the index from C volume to dedicated drives. 

The problem is, no matter how much space we add, the files just keep growing. Is the only resolution to add a massive volume to each session host for this file to grow as large as it wants? I have seen many threads on various forums where people have reached out to Microsoft support on multiple occasions for this issue and the work around is to rebuild or defrag the database. I know there are lots of these threads out there but I'm curious if anyone has found a solution yet. Thanks in advance.

RDS 2016 - HTML5 Client certificate error

Hi,

Ive recently deployed the HTML5 Web Client, at an existing RDS 2016 setup, using this guide:

https://custominterfacesolutions.com/html5-web-client-microsoft-remote-desktop-services-2016-steps-install-rd-web-client/

The setup contains 1 x RDWeb server, 2 x RDGW and 2 x Connection brokers.

A single public trusted wildcard certificate is used, for the entire RDS setup, containing the domain name, that the servers is belonging to.

Im able to login to the Web Client, and see all the published applications, that is available.

But when trying to connect, i then get an certificate error, containing the name of the Remote Desktop Session host...

Ive managed to find the certificate at the Session Host, containing the same thumbprint as the one on the picture.

Added the certificate to the trusted root cert auth, across all the frontend RDS servers (Web,GW,CB) - but that didnt help.

What seems to be the problem, since i cant find any solution to this error?

We just setup a new Windows Server 2016 as a Terminal Server. Our users are able to use Remote Desktop with no issues. However, I am unable to see the connected users in Server Manager. I was able to always view connected users in Server 2008. Should I be looking under Server Manager\Remote Desktop Services\Collections and then look at Connections? Or am I looking in the wrong place? Thank you.

Windows Server 2012 R2 showing a blue screen and no desktop!

July 17, 2015, 7:07 am

Hi

We have a Windows Server 2012 Standard R2 which is used merely as a file server. This runs on a Lenovo TS140 ThinkServer with 32GB RAM and RAID 5.

The server just shows a blue screen with nothing else, no desktop or any text whatsoever, bar the mouse cursor on the screen. The mouse cursor moves by moving the mouse. Pressing Alt-Ctrl-Del will not launch the Task Manager. CTRL-Esc will not launch the"Start" menu, nor does the "Windows" key on the keyboard.

The server is actually functional and works, as everyone can access our "Access 2013" database which runs on SQL Server 2014 Standard. Pressing the "Caps Lock", "Num Lock" is also responsive. I don't really want to reset the server by powering it off and back on again, as I'm not sure what the consequence may be.

Has anyone come across this anomaly?

Thanks for taking the time to read this post.
