Windows 2012 RDS on hyperV - DNS issue

Strange issue, whilst fiddeling arround with some certificates on the connection broker and eventualy rolling back the snapshot I was unable to contact my RD session host.
When I try to connect through RD Web Access it gives me an untrusted certificate (which is correct) and after accepting this it seems to hang in a loop, just trying to connect for ever.
Looking at the CB I found some DNS issue;
Event 8014, DNS Client Events
The system failed to register pointer (PTR) resource records (RRs) for network adapter with settings:..... (correct settings)
The reason the system could not register these RRs during the update request was because of a system problem. You can manually retry DNS registration
So I ran a ipconfig /registerdns but that gives me the same error.
I removed the connection broker from the domain and added it again. Upon moving it to a workgroup the entry on the DNS server was removed, when adding it back into the domain it appeared again. So it kind of works.
What I noticed, after removing it from the domain and adding it again, the RDP connection failed to find the server but didnt try to connect indefinatly. Once I ran ipconfig /registerdns I was back to the beginning, just trying to connect and nothing happens.
So it had some sort of effect.
I'm still unable to setup a connection to my session hosts.
Anyone??

What versions of Adobe Reader are certified for use in MS Windows 2012 RDS?

I have a MS Windows 2012 RDS (Remote Desktop Services, the new name of Terminal Services) environment. We are running Reader 11.08 now, and having extreme performance issues opening certain PDF documents, and we did not have this issue with earlier versions of Reader/ TS services. And we have tried turning off Protected Mode, Enhanced Security, to no effect.
So I have been tasked to ask - what versions of Reader are certified to work in 2012 RDS? We want to see if downgrading to an earlier version will help, but I need to know what versions will work in 2012 RDS. I see 10.01.4 available as an offline install; would that be the earliest? Previously, in Win 2003 TS, we used to use Reader v8 successfully.
Thanks

Hi MIke,
Are you still facing this issue?
Have you tried to install latest update patch 11.0.09. Do you have any GPO's for Reader. Have you tried to disable and checked again.

Windows 2012 RDS CALs - OLP NL downgrade to Windows 2003 TS CALs

Hi,
Hope someone can shed some light on this inquiry
I plans to purchase the following:
2x Windows 2014 SQL STD 2 Core License OLP NL
30 Windows 2012 RDS CALs (User or Device) OLP NL
           Breakdown example
            Site A = 10
            Site B = 5
            Site C = 15
Existing servers are Windows 2003 R2 STD running Terminal Services
Tried setting up a Windows 2003 R2 TS Server and install TS Roles & Licensing Manager
Questions.
1. When I tried to add Windows 2003 TS CALs - OLP NL, the activation screen requires to enter the Authorization & License numbers.
Can I use the Authorization and License number of the newly purchased Windows 2012 RDS CALs on the Windows 2003 TS Server?
2. Should I get a separate Authorization & License number per site? (In the example above 3x Authorization & License numbers). Or can we use a single Authorization & License number for all sites? Each site is independent from each
other.
3. As I understand, SQL 2014 can be downgraded to any prior previous version at the same editions. (as far as SQL 2000, provided he has the installer), If client has an existing SQL 2003 STD activated already, does he need to change the license key?
Thanks,
Paul

Hi Paul,
Thank you for posting in Windows Server forum.
Yes, you can use newly purchased server 2012 RDS CAL on server 2003 terminal server.
RDS and TS CAL Interoperability Matrix
For detail regarding the licensee issue I suggest you to contact MS Volume Licensing.
As per my research, I think you don’t have to change the old license key if client already have the key. And in regards to SQL server you can have a look over beneath article.

Hope it helps!

Windows 2012 RDS

Hi all I am trying to do is allow more than 2 users to be able to connect via rdp.
I understand that RDS needs to be installed on the Windows 2012 server.
My questions which RDS roles need to be installed after that, Gateway, brooker, session host?
Which role should i pick that will simply allow more than 2 user rdp

Hi,
Below are general steps:
1. Server should be joined to domain
2. In Server Manager, run Add roles and features, RDS install, session-based quick start
3. The above will create a new RDS deployment with RDCB, RDWeb, RDSH, with some apps already published
4. In Server Manager -- RDS, Unpublish the RemoteApps since based on your description it sounds like you only need full desktops
5. In Server Manager -- RDS, click to install RD Licensing
6. In Server Manager -- RDS -- Overview -- Deployment Properties, configure Licensing mode and make sure the name of the RD Licensing server is listed (it should be the server's FQDN if you installed it on itself)
7. Configure Certificates and other Deployment and Collection Properties as needed, then test.

Serious! Windows 2012 RDS cannot start / refresh anymore!

I go a problem which seems serious, please help to comment if any idea..
I have a Windows 2012 server with RDS / Hyper-V installed and configured properly; I created 4 virtual desktop collections (Win7/Win8) and they were all running well; then I tried to create unmanaged virtual desktop pool with Win7/Win8 -- somehow it
did not work and reported error message advising that the creation had failed; I then tried to create unmanaged pool with W2K8R2 and it worked -- however, RDS cannot refresh in server manager anymore, and after I restarted the server, the RDS cannot view cannot
display anymore in server manager e.g. the collections are not shown and it keeps refreshing but no output.
I tried to access RD web access and it still works -- however I can see the unmanaged pool of Win7/Win8 there which should not exist as they failed; I clicked on them and they were just empty;
I can see an error message in RDS Servers/Events saying there is a collection "NULL" so the DB visit failed;
It looks to me like Windows RDS failed to create the 2 unmanaged pools but they did get created in DB so the conflict is now blocking the RDS to continue; problem is now there seems no tool/option to fix it?
Any advice please?
Thanks,
Leon Li

So it seems I discovered this bug almost 1 year later (using Windows Server 2012 RTM + RDS/Hyper-V for VDI).
Leon Li guided me to the cause and solution (thanks!) but you must be very careful editing the WID (windows internal database).
In my case, problems started after attempting to create a new unmanaged personal desktop pool in an already working environment which hosted a single virtual desktop pool. I hesitated when creating the new pool and entered the wizard GUI a couple of
times before attempting creation. As described by Leon Li, it seem an internal counter is not reset in the GUI when creating new pools, causing consecutive attempts to fail (actually the pools are created in the background, just not completely). You can see
this by viewing the "partial" pools via rds web.
My solution was to edit the rds.pool table and remove the pools which had failed being created (it was quite simple to identify them by name, but actually the tell tale sign is a NULL value in the "ResourcePluginName" column).
After deleting the problematic rows, my server manager became responsive once again and I am able to manage existing collections once more.
To clarify, you must install SQL management studio on the connection broker and use it to connect to:
\\.\pipe\MICROSOFT##WID\tsql\query. You must "run as administrator". In there you can find the database RDCms where the editing must
be performed on rds.pool table.

Windows 2012 RDS - Session Host servers High Availability

Hello Windows/Terminal server Champs,
I am new middle of implementing RDS environment for one of my customer, Hope you could help me out.
My customer has asked for HA for RDS session host where applications are published, and i have prepared below plan for server point of view.
2 Session Host server, 1 webaccess, 1 License/connection
Broker & 1 Gateway (DMZ).
In first Phase, we are planning to target internal user
who connect to Session host HA where these 2 servers will have application installed and internal user will use RDP to access these application.
In second Phase we will be dealing with external Party who connect from external network where we are planning to integrate with NetIQ => gateway
=> Webaccess/Session host
I have successfully installed and configured 2 Session
Host, 1 license/Broker. 1 webAccess & 1 Gateway. But my main concern to have session Host High Available as it is hosting the application and most of the internal user going to use it. to configure it i am following http://technet.microsoft.com/en-us/library/cc753891.aspx
However most of the Architecture is change in RDS 2012. can you please help me out to setup the Session Host HA.
Note: we can have only 1 Connection broker /Licensing server , 1 webacess server & 1 Gateway server, we cannot increase more server due to cost
factor.
thanks in advance.

Yes, absolutely no problem in just using one connection broker in your environment as long as your customer understands the SPOF.
the session hosts however aren't really what you would class HA - but to set them up so youhave reduancy you would use either Windows NLB, an external NLB device or windows dns round robin. My preferred option when using the connection broker is DNS round
robin - where you give each server in the farm the same farm name dns entry - the connection broker then decides which server to allocate the session too.
You must ensure your session host servers are identical in terms of software though - same software installed in the same paths on all the session host servers.
if you use the 2012 deployment wizard through server manager roles the majority of the config is done for you.

Windows 8.1 Junos Pulse DNS issue

We have windows 8.1 enterprise installed fresh, not an upgrade. When we connect to our VPN we cannot ping our local 10 addressed DNS server names, when we have the DNS prefix's filled out in our network adapters TCP/IP properties. However when we dont have
them filled out, it works fine.. Is there a GP that we need enabled or a checkbox we are missing.. I can attach the working and non working properties screen if need be. Any help would be greatly appreciated.

Windows 2008 R2 Remote Desktop Service Role pickup 2012 RDS License Server.

I am installing Citrix onto a Windows 2008 R2 server as part of this I need to setup the RDS Role on the same box and then point it to the Windows RDS License server.
Our plan is to have a Windows 2012 License server for RDS Licenses i.e. install 2012 RDS Licenses.
I was wondering if it was possible for a 2008 R2 RDS role to pick up 2012 RDS Licneses from a Windows 2012 RDS Server?
Many thanks,

Installation of Exchange 2010 in Windows 2012 Server

Hi all,
We are planning to upgrade our current Exchange 2003 to Exchange 2010, Need some help on installation and Support of Exchange 2010 in Windows 2012 Server, as per the
https://technet.microsoft.com/library/ff728623(v=exchg.150).aspx Exchange 2010 with sp3 is supported in Windows 2012 but I am unable to find the installer of Ex 2010 with sp3
in web even in MSDN. There is only Ex 2010 with Sp1 available. I know that after installing ex2010 with sp1 version, I can install sp3 later but I found one link
http://www.petenetlive.com/KB/Article/0000785.htm where it is mentioned that insllation can be done only after doing the registry settings.
So is any one who has installed Ex 2010 in Windows 2012 Server and faced this issue and any solution.
Thanks
Mukesh
Mukesh Bisht

You can easily install Exchange 2010 (SP3) on Windows Server 2012. If you are working with previous SP version’s you can easily upgrade after installing server. And registry settings
are used to fix an error which may occur during migration, so it is not mandatory to correct registry settings each time during migration.
You can find detailed information about installing Exchange 2010 (SP3) on Windows Server 2012 at this blog :http://oxfordsbsguy.com/2013/03/24/how-to-install-exchange-2010-sp3-on-windows-server-2012/

How do I show remote printers in Windows 2012 RDWEB?

Hi everyone,
I have setup an Windows 2012 RDS host and am able to access it externally by using https://remote.domain.com/rdweb.
Therefore I can log in and launch remote apps.
Local printers get redirected, but I do not seem to be able to see the remote printers on the RDS server.
The printer is installed and it is installed on the server.
What if I want to print on the server printer rather than my own printer?
How to get to show the printers in the RDWEB page?
I do not get control panel, select device and printers here.
Can someone enlighten me on this?
Thanks very much.
Regards
Ipnotech

Hi,
Any takers for this question?
When I use internet explorer to access the Windows 2012 r2 RDS server by typing https://remote.domain.com/rdweb, I get to logon and can see all my published apps and launch them.
But when I print from a remote app I can only see my own redirected printers I cannot see the network printer which is installed on the server.
I tried to change group policy under Computer Configuration/Administrative Templates/Windows Components/Remote Desktop Services/Remote Desktop Session Host/Printer Redirection and set:
Do not set default client printer to be default printer in a session ENABLED
Use Remote Desktop Easy Printer Driver first ENABLED
Redirect only the default client printer ENABLED
Then I run a gpupdate /force on the RDS host to apply the policy to the server.
When I connect remotely from a Windows 7 client using IE and lets say I launch the wordpad remote app I can only see my client printers not the server printers.
This seems to work if I RDP into the server with mstsc.exe but not using RDWEB.
Does anyone know about this?
Thanks and regards

Setting Up Remote Desktop Services Windows 2012 DMZ

Hi
I'm new to the Windows 2012 RDS. I am trying to figure out some things.
I have an application that I would like to publish to the outside world to our customers.
Im thinking of using Windows 2012 remote desktop services and publish the app via web browser. So users go to the URL and see the application.
Do I need a client brooker and gateway server for this setup? or can i simply deploy a web access server on the dmz which then connects to my remote session host server inside?

Hi,
To allow outside access into your RDS environment you would need to use the RD Gateway role. This can be configured on the same box as your RD Web Access role if resources are limited.
The RD Gateway role uses ether TCP 443 or UDP 3391 depending on what you have chosen to configure. You need to create a port forwarding rule from and to the gateway box using 443.
Have a look at the following articles:
http://ryanmangansitblog.com/2013/03/27/deploying-remote-desktop-gateway-rds-2012/
http://ryanmangansitblog.com/2013/03/10/configuring-rds-2012-certificates-and-sso/
This should assit with the configuration.

Windows 2012 R2 RDS Licensing Issue

I setup RDS License Server role in our domain controller server and installed open license RDS User CAL. From the connection broker server, I setup RDS Deployment's RD Licensing to per user and added the domain controller from the license server
list. RD Licensing Diagnoser output is ok and able to detect the license server. All servers are windows 2012 R2.
Now the issue is, when using RD Web access and launching the application, the license manager is still showing 0 issued license. Tried opening several sessions, more than the number of license seats available and still RDS still works fine. Wondering
whether license server is functioning properly. Let me know if someone experienced the same thing.
Thanks!
Joe

Hi Joe,
Thank you for posting in Windows Server Forum.
Have you find any specific error\event id for this case?
As you have Per User CAL and to see your Per User RDS CAL usage you need to create a report, save it to a .csv file, and then view the csv file in Notepad/Excel. We can do this in RD Licensing Manager by right-clicking on the server name, choosing Create
Report - Per User CAL Usage, and then after you have the report right-click on it and choose to save it as csv.
Hope it helps!
Thanks.

Windows Server 2012 RDS CALS on Windows Server 2008 R2 Licensing Server

Hi,
at the moment we are installing the first couple of Windows Server 2012 in our infrastructure.
Some of them have installed RDS.
Now we are wondering whether it is possible to use our existing Windows Server 2008 R2 licensing server for serving the licenses we have (yes we to have new Windows Server 2012 RDS CALS) or whether we have to install a new host based on Windows Server 2012.
We tried to add the new license to the 2008 R2 licensing server, but it is not possible. The licensing manager's error message: "The license code contains invalid characters or not enough characters."
Is there any other way?
Thanks and regards
Matthias

Hi matt_will_fix_it,
How about Windows 2012 R2 ?
Will a Windows 2012 RD Licensing server provide licences to a Windows 2012 R2 server?
I have not tested it, but it should work. Server 2012 R2 requires the same RDS CAL version as Server 2012. If you try it and have an issue please reply back.

Windows 2012 R2 / Windows Essentials Role. How to keep from Changing DNS.

So I have asked this question in the windows 2012 Server board and was directed to try it here in the essentials.
that existing thread is here >>
http://social.technet.microsoft.com/Forums/en-US/11cfbc1b-0001-42d6-85c1-304d1e450679/windows-2012-r2-windows-essentials-role-how-to-keep-from-changing-dns?forum=winserver8gen
now to the question
Ok so I will describe my problem as best as I can.
I have 2 Servers Both 2012 R2 Standard 1 is Primary Domain controller and one is the Secondary Domain controller. I had everything set up on the domain and the Primary Domain controller was set up as the DNS on ALL clients (Static).
Recently I set up the secondary domain controller with Essentials. All went well I added all the clients to connect with Essentials. a few days went by and now all of a sudden all the Static DNS's are all changed to the Essentials box.
This Really wouldn't be a problem to me except the performance level of that DNS is EXTREAMLY slow. I run to all clients and change the static back and everything works great. then a little while goes by and all DNS's are again to the Essentials box.
SO my question would be. Is there any way to configure the Essentials box to stop redirecting the DNS to itself and keep the Primary domain controller as the DNS

Hi Curtis_bob,
I noticed that Olaf had provided
KB2862551 in the old thread. Just check if Olaf’s suggestion can help you to solve this issue.
If this issue still exists, would you please let me confirm whether has also installed DNS server role on the
Windows Server 2012 R2 Standard (with Windows Server Essentials Experience role)?
If any update, please feel free to let us know.
Best regards,

Multiple RDS Device CALs Issued through Windows 2003 RDS Hosts

Environment
Windows 2012 R2 RDS license server issuing device CALs
5 Citrix farms (PS4, PS4.5, XA5, XA6, and XA6.5)
Symptoms
- RDS device CALs issued through the PS4/Windows 2003 R2 and PS4.5/Windows 2003 R2 servers show the Citrix server name in the Window 2012 R2 RD license manager console instead of the workstation name (See below).
- The PS4/Windows 2003 R2 and PS4.5/Windows 2003 R2 servers are issuing a large number of device CALs to workstations. For example, we have two PS4/Windows 2003 R2 servers that publish a single application. There are 20 users
of the applications with dedicated workstations that should all have a device CAL, but everyday I see device CALs being issued from these servers (See below).
Any help would be greatly appreciated. Thank you.
Scott

Hi Scott,
Thank you for posting in Windows Server Forum.
Have you find any Error\Event Id for this case?
From the description it appears that there is some misconfiguration for redirecting the server during load balancing the device CAL among the server and that’s why device is getting misplaced. You can please relook at configuration for License server with following
article.
