Windows 2012 R2, the issue suddenly happens, RDP no longer working. I checked all the following below and they are all good.

1. Registry key - RDP is enabled

2. GPO (local and domain) - not settings for RDP

3. RDP services are running

4. RDP session is enable in Windows

5. Port 3389 is open and listening

The following RDP tests and failed!

1. RDP by FQDN

2. RDP by its IP

3. Loopback RDP with 127.0.0.1

All three tests above gave the error message shown

What else I can check to fix this? thanks.

Windows server 2016 RDS - Printer driver installation

Double clicking on a print server queue, a regular user can trigger installation of a printer drivers through "point and print".

This shouldn't be allowed. Only administrators should have rights to write (or trigger writing) in C:\Windows\system32\spool\DRIVERS\

At least this was not allowed in W2008 R2 RDS.

Windows server 2016 - Software Restriction Policies - Designated File Types

Hi

After applying a software restriction policy GPO, servermanagerlauncher.exe won't run.

This program is scheduled to run "At logon of any user" (rather Administrators) and it returns the popup error "This file does not have a program associated with it". ???

Any other executable runs fine, in particular ServerManager.exe runs well.

This GPO reset the list of "Designated File Type", in which EXE is present.

This GPO was set (a long time ago for W2008 RDS) to remove LNK (i.e. shortcuts) from the Designated Files Types. So any shortcut can be run from anywhere (i.e user's dekstop), while the real executables (Designated File types) are allowed only from specific locations (Basically C:Windows\ and c: \program files).

What's specific with servermanagerlauncher.exe ?

Authentication Steps for RDS 2012 R2

I am troubleshooting some issues with RDS and the security tools deployed in our environment and would like to ask if anyone can provide details on the authentication steps for a 2012R2 RDS farm.

I have a Web Access, Gateway, Connection Broker and 2 Session Hosts.

I provide credentials to log on to the WA and successfully get the icons for the available apps. When I click on a icon I get a "Do you trust the publisher..." prompt and respond "Connect". I then get prompted for credentials which provide (correctly) and I get "Your credentials did not work..." and asked for the credentials again. When I enter the same credentials the second time the remoteapp opens successfully.

I have reviewed the event logs but can't quite piece together the authentication steps to figure out where and why this fails the first authentication attempt but then passes the second and opens the app.

Does anyone have any docs of links that explain, step by step, the authentication steps involved?

Thanks in advance.

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

Cannot RDP to servers via hostname, but IP is OK?

We had a major issue today in one of our sites where we could not RDP to server via their hostnames (tried FQDN as well) but when we tried the IPs of the servers it works OK. The times & timezones on all servers were spot on so no issues there. All IP details were as they should be and nothing had changed yesterday or today.

We tried IPCONFIG/FLUSHDNS, IPCONFIG/REGISTERDNS on all servers and nothing fixed the issue. We restarted the domain controllers and still nothing. Tried setting the DNS server IPs to those of domain controllers in other sites and still nothing.

What worked was that we had to reboot each server having the issue and that fixed the problem. Ony thing was that we have around 10 servers, all in production, with the same problem but the other 90 or so servers were not affected!?

Set up Clustered Hyper-V RD Virtualization hosts?

January 19, 2017, 2:51 pm

I have a VM running Broker/gateway/RDWeb, which is working fine.  I'd like to add RD Virtualization hosts for full desktop VDI.  I have two servers in a cluster with shared fibre SAN storage, but I can't figure out how to point the RDS environment to use the cluster resource for the RD virtualization host.  If I point the RDS set up to the cluster name/IP for the RD Virtualzation host, it fails.  If I point it to the individual nodes of the cluster, it installed, but this is useless to me as their shared storage is only active on one node at a time.  

How can I get both nodes with RD Virtualization Host roles installed to be clustered in such a way as to have the cluster itself (or a clustered resource) be available as the RD Virtualization host?

RemoteFX + Tablets

January 20, 2017, 3:23 am

Hello,

My project is the following one :  i am working in a security company which sells intrusion-detection and video-surveillance solutions.
One of our clients is having issues with its existing solution because we underestimated the need of the software we implemented.
The software is named "Genetec - Security Center". It is based on a windows server 2012 R2.
The server is perfectly ok, but the client parts is far from being ok.
We sold tablets, which are overused by the software, which cause them to freeze, lose connections to the server, etc. And most of all, they are slow.

The main issue is that, because they are tablets, the graphics are generated by the UC. They  are not designed to support that kind of load and usage.
We have 7 tablets plus the server, all linked to the network with Cat.6 cables on a dedicated Local network.

The solution i am studying is to create a new server, to work aside of the first one, and the new server would be dedicated to RemoteFX which by it, i would use the LAN and make remote sessions to ease the load of the tables by using them only for making remote sessions, the rest would be taken cared of by the new server.

I have to display 6 cameras per screen, resolution : 1080p, for the cameras and the screen resolution of the tablets.

So i have several questions like :

-Is such a solution is a good one? If not, what are my other options?

-Considering the fact that i have 7 tablets to run simultaneoulsy, which would be better?  Create via Hyper-V, one virtual machine per tablet, or could Terminal Server be a better solution, regarding the price, the eased management, etc. ?

Thank you for the advices and/or solutions.

How to set TZ for different RDS users

January 19, 2017, 2:46 pm

I have some apps that are TZ sensitive on our 2012 RDS farm, as such TZ redirection is enabled in group policy.

The issue I have is one particular app requires the user TZ to match the local server which is in AU.  I have users in NY and other US regions using this app and they get TZ errors from the app because their local date differs from the server date.

Because the client redirection is a computer setting in GPO I can't turn off TZ redirection for specific users.  I've tried creating a targeted login script that runs TZUTIL and sets the zone to AUS +10 however I find this is hit and miss, sometimes it works sometimes not or it works the first time but if they reconnect it goes back to their local time. I've also seen it change the TZ to AU time when you first login but then 10 mins later it changes back to the remote clients TZ

Any suggestions how I can overcome this. 

I understand that the config may be mutually exclusive for the apps that require AU time and others that need actual local time but this is OK, the users of the apps are different roles and need one or the other.

Remote Desktop default printers not setting

Our scenario is mac based and we use remote desktop to use windows applications we can't run on them.

There's one problem with printers <g class="gr_ gr_45 gr-alert gr_spell gr_disable_anim_appear ContextualSpelling" data-gr-id="45" id="45">though</g> on their remote desktop login, no one is able to set their own user specific default printer.
You set the default and everything is working fine, till you log off then back on.. what will happen is the printer default is the first printer but then their printer has duplicates installations of it, you can tell this when you right click the printer and it asks which printer you want to change i.e. 
>samsung 1234
>samsung 1234
>samsung 1234

I then have to delete their local profile and get them to log back in again for it to go back to normal, their printer <g class="gr_ gr_32 gr-alert gr_gramm gr_disable_anim_appear Grammar multiReplace" data-gr-id="32" id="32">is then default</g> without multiple installations of the same printer, till they log out and back in.
I have even recreated their profile and given them a new one but it's still the same issue.

Any ideas? GPO is not set for any defaults etc

Might be worth mentioning that we have two servers for active directory logins of rds1 and rds2, it will split the users onto both servers to share the load. If one person is logged into rds1 then the server will redirect them to rds2. We have to delete both profiles on both servers, is there a link issue here because of the two profiles?

W2016 - RemoteFX setup for fluid video rendering and low cpu

Hi,

I noticed that w2016 RDSSH (virtual machine non-hyper-v) will uses twice as much cpu than w2008 r2 when rendering video. That's a big disappointement.

There is a RemoteFX GPO for W2008 R2 to set frame rate and video quality. I had set for a fluid video rendering (i.e. High frame rate and medium video quality). Watching videos is not at all the main purpose of my servers and the service is fair enough w/ w2008 r2.

Is there a similare setup for W2016 ? Or any other tweak to get fluid video and low cpu ? (Network bandwidth is not a problem. All clients are 100Mb/full)

301_Error Microsoft-Windows-TerminalServices-Gateway "23002"

January 23, 2017, 7:14 am
$

I'm trying to reproduce an error we get when a user tries to connect to a non-persistent VDI pool. Sometimes, the user will be denied access to a virtual machine in the pool and the following error gets logged:

The user "DOMAIN\user", on client computer "172.21.1.131", did not meet resource authorization policy requirements and was therefore not authorized to resource "172.18.36.70". The following error occurred: "23002".

The client computer IP is a Threat Management Gateway (TMG) and the resource IP is from a DHCP pool.Both the CAP and RAP at the RD Gateway are custom and have all the necessary settings.

My first assumptions are that there is a gap between the time a VM gets a new DHCP lease and gets registered in the DNS and the refresh from the RD Broker database, but I might be wrong. The DHCP time lease for that scope is 5 hours.

Would anybody have a good knowledge of how the different components of an RDS farm works or, better yet, could explain why the user gets this error, but not every time..

Thanks

Problem with printer drivers

January 24, 2017, 4:08 am

Hi,

I have a Windows 2003 Terminal Server server. Clients connects to it with RDP, to use Office applications and view PDF Files. The server has a number of different printer drivers installed. For example:

- HP Laserjet 500

- HP color Laserjet 200

- HP Universal Printer Driver PCL5.

And about ten more drivers.

Clients connect to server and have diferent printers, each with each driver. The problem is that, whatever model of printer the client has, with whatever driver it has installed, the mapped printer in the server takes the HP 500 Driver. So every single printer mapped in the server, is being mapped with the HP 500 driver, despite the server has installed the correct driver for all the printers.

How can I achieve that if I use in a client a printer which driver is installed on the server, the server maps the printer with the correct driver instead of the HP 500?

Work Resources Folder Not populating

We had an issue yesterday where the user profile disks got disconnected while users were in the system.

Afterwards some users "Work Resources" folder in the start menu are empty. Updating via Control Panel does not repopulate. The wizard just sits and stays on the screen that says "Adding Resources".

I found an article that suggested deleting everything in the Feed key in the registry and emptying the Work Spaces folder then trying again, but this did not work for me. 

Looking at event viewer I see the following error:

"The following resource could not be downloaded: https://myrdwebserver/RDWeb/Feed/rdp/cpub-DLX-PROGRAM-CmsRdsh.rdp 

Event ID 1017

Error code 0x80070003

Next step will be to create a test user account and log onto the PC with that account and attempt to populate the folder to see if it is profile related.

Server 2012R2 RDS Profile

January 18, 2017, 11:24 am

Hello everyone,

Is there any way to restrict multiple concurrent RDS sessions in a Server 2012R2 RDS farm to the same server.  I am trying to migrate our environment from independent RDS, to a farm environment.  Citrix is out for at least this year.  I would like to implement a centralized profile management, but our users need to be able to have multiple RDS sessions for business needs.  With UPD's, since they are mounted at login, can only be used on that server.  Roaming profiles only write back on logoff so no real-time advantage there.  Folder redirection would be ok, but doesn't do anything for settings, printers etc...  I liked the way UPD's worked when multiple sessions were on the same server.  Thanks for any info.

Chris
