2012 RDS Collections and Domain Groups

March 13, 2019, 12:21 am

I have an rds farm with three rds_host servers. I have defined three domain user groups for sage_sales, sage_admin and sage_outside.

I have three collections pointing to the three rds host servers; sage_sales, sage_admin and sage_outside.

In my tests:

When I setup a user Joe in the Domain user manager, and make him a member of the sage_admin group, he can log into the RDWEB portal by entering his domain.user/password and clicking sign in. He is presented with the collection icon as shown below.

Clicking on the Sage_Admin icon takes the user to a successful remote session on the correct rds host configured for sage_admin users.

When my test user Joe is a member of two groups (sales_group and admin_group), he is presented with two collection icons after signing into the rdweb portal as shown below:

However Joe can only connect using the Sage_Admin icon. When clicking the Sage_Sales icon, the following error dialog is displayed.

What is happening here? I can't find any difference in the group rights.

Does the Set Primary Group in the Domain User settings effect which icons are available in an rdweb session?

Comments on these configuration options would help. What a battle!!

Windows 10 - Remote Desktop serves Black Screen

Hi Windows 10,

I am having an issue with Windows 10 - every day.

But last 3-6 months, remote desktop connections fail with a black screen on my network!

Now I have started to feel true hate towards this OS, as this error, now seems to settle as a forever error that will stay?!

Issue is using RDP to other Windows10 device on my network, now serves a black screen after connection has been idle for some time - or it just turns black, just as i log in?!

I am able to remove black screen - only if disconnect, and reconnect. But again. After some time. I get a black screen again?!

As Windows continues with their disapointments towards the proffesionals on Windows10 since release.

This error in question, I really want fixed - to be working as it has always been - since the dark ages . RDP should just work! Every time - all the time. 

So anyone - before I look up a lawyer to fight this - Please assist with the right trick to get this fixed......

Awaitng that true fix------ anyone?

Regards, Kato.

ERROR: This RDP file is corrupted. The remote connection cannot be started.

I have created 2 new remote app connections for different modules of the same application in TS 2008 R2. I am trying to launch them via a remote apps web front end on a Win7 Enterprise workstation fully patched.

One connection works fine but the other errors out immediately with "This RDP file is corrupted. The remote connection cannot be started." If I do not digitally sign the connection to the remote app site both connections work fine. All other connections published on this server work fine.

Thanks

Ghost typing the letter G

We have a 2016 standard server to which a few employees connect to for Terminal Services. Only one client using Windows 10 has suddenly developed an odd problem. The letter "g" keeps being printing. It doesn't happen on the computer itself, just in TS. I removed all peripherals thinking maybe there was some signal being transmitted from there, but still happens. Any ideas?

Windows 2008 R2 RDS and Windows 2016 DC's

We have a Windows 2008 R2 environment mostly. Our current DC's are Windows 2008 R2, yesterday we introduced 2 new Windows 2016 DC's and this morning we found that once some of our RDS servers started to query the new DC's users would get an "Access Denied" error trying to establish a connection. We found a reg setting to to have the RDS server ignore the error so users could log in, but then once a connection was established it was with a local profile, not a roaming profile.

In order to resolve the issue we powered off the 2016 DC's.

Anyone know what happened here and what we need to do to power on the 2016 Domain Controllers again.

Thanks.

licenses are not getting issued to my session host server

Hello Team,

I have 30 session host servers and I am using non persistent servers where my users will simply login and use it for a day and log off. Whenever they log off the server will get back to its initial state and all the changes made to the servers will be lost.

I have purchased the Per user licenses and configured them. I have installed licensing role on the sever and applied the below group policies to my session host servers.

  • Computer Configuration\Policies\Administrative Templates\Windows Components\Remote Desktop Services\Remote Desktop Session Host\Licensing\Specify RD License Servers - I have specified my licensing server.
  • Computer Configuration\Policies\Administrative Templates\Windows Components\Remote Desktop Services\Remote Desktop Session Host\Licensing\Specify the Remote Desktop licensing mode - I have specified per user licensing mode.

But the licenses are not getting issued. These servers are still depending on 120 days grace period. In the event viewer it says "  The Remote Desktop Session Host server does not have a Remote Desktop license server specified. To specify a license server for the Remote Desktop Session Host server, use the Remote Desktop Session Host Configuration tool". 

I am wondering that I have already specified the group policies and still it displays the above error. 

I tried deleting the grace period registry key as I read in on the forums, since these are non-persistent VM's at the end of the day the registry key will regenerates and starts issuing the free licenses. I am afraid now, what happens after 120 days?

There are no error messages on licensing diagnose? Please advise is this a kind of bug or something else?

Any kind of help is much appreciated

Thanks,

SM

RDS Servers Events 7011, 7046 - BSOD rdbss.sys

March 14, 2019, 3:42 pm

Hi All

I have a virtualised (VMWare) RDS 2012R2 environment with 20 Session hosts spread across 6 Dell ESXI Hosts - 2 Sets of different PowerEdge Models. Over the past 4-6 weeks we have started to get multiple event 7011's followed by a 7046.

A timeout (30000 milliseconds) was reached while waiting for a transaction response from the UmRdpService service.

The following service has repeatedly stopped responding to service control requests: Remote Desktop Services UserMode Port Redirector

At this point some existing connected users cant sign out and applications start to crash including explorer.exe. Trying to shutdown via the GUI just hangs and the only way to get the server back is to reset the power using vSphere console. 

Applications on the Session Hosts are mainly MS Office 2016, Acrobat Reader, 7Zip and Webroot AV. Windows OS and applications are fully patched and up to date and Dell Firmware and drivers are fully up to date. 

Users connect in via RemoteApp and local drives and printers are redirected into their sessions. 

The weird thing is, like clockwork the crashes happen at the end of each day usually between 16:00 - 18:00 - To me its like a degradation symptom or perhaps its the actions of users disconnecting or logging off their session - Its affecting a couple of servers each day. 

On top of this, it appears 7011, 7046 results in a BSOD. I have grabbed the Memory.dmp file and opened it with WinDbg. 

Im now trying to figure out the dmp - uploaded to PasteBin here (happy to paste dmp here but didnt want to "dump" to much information in the post)

What stands out to me is rdbss.sys

Probably caused by : rdbss.sys ( rdbss!__RxAcquireFcb+1f3 )

IRQL_NOT_LESS_OR_EQUAL (a)
An attempt was made to access a pageable (or completely invalid) address at an
interrupt request level (IRQL) that is too high.  This is usually
caused by drivers using improper addresses.
If a kernel debugger is available get the stack backtrace.
Arguments:
Arg1: 0000000000000000, memory referenced
Arg2: 0000000000000002, IRQL
Arg3: 0000000000000000, bitfield :
bit 0 : value 0 = read operation, 1 = write operation
bit 3 : value 0 = not an execute operation, 1 = execute operation (only on chips which support this level of status)
Arg4: fffff80179d3ba44, address which referenced memory

BUCKET_ID:  AV_rdbss!__RxAcquireFcb

PRIMARY_PROBLEM_CLASS:  AV_rdbss!__RxAcquireFcb

My rdbss.sys version - 6.3.9600.18895

Can anyone help to try and decipher the above and suggest next/best cause of action?

Many thanks :)

Remote Desktop fails to connect on Windows 7 for users who have been assigned administrator rights. [The Local Security Authority cannot be contacted]

February 19, 2019, 10:32 am

Everything was working fine until about 2 months ago.

I have a Windows 7 system that I access with Remote Desktop Connection from a Windows 10 system.  One day I found that my user account, which had been given administrator rights quite some time ago, couldn’t log on remotely.  The Windows 7 system was configured for remote access with the setting “Allow connections only from computers running Remote Desktop with Network Level Authentication (more secure)”. When I tried to log on, I got an error stating “The Local Security Authority cannot be contacted”. 

If I configured Windows 7 to “Allow connections from computers running any version of Remote Desktop (less secure)”, then I could log in but I didn’t want to use this less secure setting.

Doing some experimentation, I found that if I enabled the built-in Administrator account, then the Administrator could log in remotely using “Allow connections only from computers running Remote Desktop with Network Level Authentication (more secure)”.

If I created a new standard user called Test.  I found that Test could also could log in remotely using “Allow connections only from computers running Remote Desktop with Network Level Authentication (more secure)”.

If I promoted Test to an administrator, then Test couldn’t remotely log on.  He got the LSA error.  If I demoted my account to a standard user then I could log in remotely using “Allow connections only from computers running Remote Desktop with Network Level Authentication (more secure)”.

When I promoted my account back to an administrator, the logon failed with the LSA error.

All users have valid passwords that are set to never expire and are members of the Remote Desktop Users group.  The only thing that is changing is whether or not the users have administrative privileges.

Is this a permissions issue, or a behavior change cause by an update to Windows 7?

The logon attempt failed when connecting to multiple RDP sessions

Whenever I connect to more than one RDP session that is through a gateway, some of them will not allow me to log on.  I get the error "The logon attempt failed" and that is all.  If I disconnect from some of the other sessions and reboot my computer, I can then connect to the server that was given me said error.

I can also connect to the server giving me said error without closing down other sessions or rebooting by connecting through a Hyper-V virtual machine on my computer. 

None of this makes any sense.  Has anyone else seen this behavior?

RemoteApps - is there such a thing as an "approved list" of apps that can leverage this technology?

Hello and thanks for the help.

I'm trying to find a solution for allowing external users on a different domain to securely access TFS from their copy of Visual Studio to check-in/check-out code. 

I'm using a Privileged Access appliance that has a technology that allows folks to start applications remotely like this, but the rep told me they do not think I could use Visual Studio in this kind of manner because it is not on the "approved list" of RemoteApps.

I've been looking for a little while and can't find any sort of list of approved Microsoft RemoteApps.

It's difficult to search for this because it always brings back error-related threads.

Does an approved list of software for RemoteApps exist and if so, where can I find it?

Which license should i purchase for terminal access in server 2016 with workgroup setup. All our users are in workgroup and there is no  domain setup in our company. its a small office and we are accessing the server(around 12 users) via remote desktop(with LAN only). Earlier it was  server 2003(workgroup only) and have 15 userCAL licenses  in it, it was working fine.
recently we purchase this new server with server 2016 and also purchased 10 userCAL licenses. new server is up and running and enabled remote desktop services also, its working fine now(without RDS license. should be in free grace period). Is that my userCal licenses will work with this or do i need to purchase devCAL for this setup?

Handle Remote Desktop Idle timeout

March 7, 2019, 9:24 pm

Hi, 

We want to use RDP for connecting to remote machine, execute Desktop Application Automation there. The challenge that we face is that on the customer end there are restrictions on idle timeout in RDP session. Once we start executing the automated desktop application and if execution takes longer that than the idle timeout to execute, the remote desktop session ends, and the Desktop Automation fails. Is there a way to handle this?

1. I have tried TSCON, but TSCON unlocks the console session, so it may not be acceptable to customers.

2. I have also tried Java's Robot classes to do some mouse action(https://stackoverflow.com/questions/52874/how-do-you-keep-the-machine-awake) This also works with limited scope. In case the RDP session loses focus, it does not work.

Is it possible to keep the RDP session from disconnecting on Idle Timeout?

Thanks in Advance.

Best,

Sumit

Cumulative Updates breaks RDP since November.

We have an RDS server (2016).  Since November or October, every cumulative update (well until Jan, haven't applied latest yet), breaks RDP. We can connect to the gateway fine, but accessing the RD desktop just fails with a warning about not being able to connect.  If I uninstall the Cumulative update, then all works again.

Event log shows hundreds of Schannel events (A fatal error occurred while creating a TLS client credential. The internal error state is 10013.)  The remote desktop management service fails to start and the server manager shows this issue:

the server pool does not match the rd connection broker that are in it. errors

Any ideas on how to fix?
