Remote Desktop Gateway : How to set local adresses range

March 8, 2013, 3:09 am

Hi All,

I'm using RDS 2012 to share some applications.

I'm using a RD Gateway to let internet clients use the published applications.

Today i'm facing a problem that I want to share with the community, and i'm sure it's a good topic.

I want that only internet clients use the RDGateway server, so I decided to check the option "Bypass the Gateway for local addresses"

The question is how the mechanism detects that it's in a local range or in a internet range.

The problem comes after some users in a branch office (connected to the main office via MPLS, not internet) reported me some performance issues, after I checked I found that they are redirected via the gateway, it's not my aim, I want only internet clients to be redirected via the Gateway.

The solution is : Is there any configuration file in the RDS server where I can configure and let the RDS server now the range and the source addresses that I want to be considered as local ?

Deploying remoteapps from Windows Server 2012 to Windows XP clients

Hi,

How would we go about deploying programs to our windows xp clients (non domain joined, external clients) from server 2012? In Windows server 2008 R2 we've done this using MSI's, but this option is removed in 2012. 

Is the only possible way for them to open the browser and go to rd web access every time they want to start a program?

Thanks

Windows 2008 Terminal Server "user must change password at next logon" problem with Windows 7 client.

Hi,

I have a fully patched Windows 2008 SP2 Terminal Server and a fully patched Windows 7 client.

I have logged into the Windows 2008 SP2 Terminal Server server with a test account via RDC before.

When I try to log in via RDC to the 2008 TS with a test account which has been marked with the setting "User must change password at next logon" I get the RDC message "You must change your password before logging on the first time.  For assistance, contact your system administrator or technical support."  I need to force the user to change their password once it has been issued, any ideas on how this can be done?

Thanks,

Dan

We have implemented a new Server 2012 RDS server.   Our domain now has 3 RDS Servers.   Two are Server 2008 and a new Server 2012.    We have a problem where the new Server 2012 server will not allow access to a clients local drives.  The two Server 2008 work just fine.

Does anyone know what the problem might be?

Remote Desktop Gateway behind a NAT firewall

I created a self signed certificate using the same name that clients will be using to connect from the outside. I installed that certificate on my home computer. I forwarded port 443 to the RDG server. I can ping the hostname from the outside just fine (the response from the NAT firewall is received). But when I try to connect, it errors as though the server itself were not even up.

Problem exposing Remote Desktop Gateway to the outside - SSL issue

March 8, 2013, 4:31 pm

our remote desktop gateway is part of our local active directory domain. So it has a hostname of rdgsrv01.ourlocaldomain.local. I can connect to the RDSH server just fine through the RDG server, from a workstation on our internal network. Now I want to connect from a workstation outside out of our network and I keep getting a certificate error. 

How would the proper configuration go for that to work? 

We have a public domain.com. So I created the public host record "rdg.ourdomain.com" for our clients to use. On the RDG server itself, I created a self signed certificate using the same domain name "rdg.ourdomain.com". I imported it so that it's displayed in the section of the RD Gateway Manager where it says "The following certificate is installed on RDGSrv01:"

But it seems that the SSL certificate of the remote desktop gateway server MUST match the FQDN of the server itself. If that is the case, how can this server be accessible from the outside if no one can communicate with ourinternaldomain.local, being that is a private active directory domain? Do I have to add a hostfile entry for that on the remote computer then use the original certificate on the RDG server?

It works fine when I do that. But adding a hostfile entry for our private active directory domain on all remote computers does not seem like a practical solution.

Terminal Server - Preventing session stealing

Hello.

I have a client with a peculiar TS enviroment:  they use Terminal Server (running in a W2K3 R2) as the main server, and all users access it via thin-clients or Linux stations with RDESKTOP. All of the users uses the same account for loggin into the TS.

Here's the problem: from time to time, some users steals the other's session, since it's the same login account.

Is there a way to prevent it? It's impossible for them to create a user per employee, because this change doesn't reflect their bussiness necessity.

RDS in Windows Server 2012 - Untrusted cert issue when connecting to the RDG

March 8, 2013, 10:10 pm

Hi guys,

I am migrating from a Windows Server 2008 R2 RDS deployment to Windows Server 2012 RDS. In fact, it's nearly complete except for a certificate issue that I can't seem to nail down. 

Issue:

Some client machines (Win7/8) are unable to connect through the new 2012 RDG due to an untrusted certificate error. Our users RDP through the RDG to either Windows remote servers or to a 2012 RDSH. No RemoteApps.

Symptoms:

Using mstsc.exe, here's the error that comes up right after entering creds when prompted:

'This computer can't verify the identity of the RD Gateway "publicA-record.domain.com". It's not safe to connect to servers that can't be identified. Contact your network administrator for assistance.'

There is no option to ignore, the user simply is not allowed to connect. This occurs for all remote servers they are trying to connect to.

There's a view certificate button on that msgbox, and here we see our wildcard cert with these notes:

''Windows does not have enough information to verify this certificate."

"The issuer of this certificate could not be found."

The certificate path on the wildcard certificate lists only itself. There should be three levels: itself, the intermediate CA, and root CA.

Notes:

We reused the same Entrust CA wildcard certificate from the old 2008 R2 RDG onto the new 2012 RDG. I used webdeploy to move the IIS site over. It required a password, so I am assuming that the cert's private key was copied over as well. (How can I administratively confirm this?)

All users can still connect to the old RDG without issue. Those that get the error above can connect to the new 2012 RDG after installing the Entrust intermediate CA cert. 

Interesting observation: on my Win8 machine, one user account can access both the old and new RDGs without issue. On the same machine, on another account, the untrusted cert issue above is seen. 

Here's our setup:

1x Server 2012 RDG

1x Server 2012 RDSH - also Connection Broker, Web Access (not used), and not in a farm configuration

Is there a certificate setting I missed? Really weird because every thing looks right, and others are able to connect to the new RDG fine from the get-go. Are there changes in IIS8 or elsewhere in Server 2012 that would cause this?

Thanks!

Migrate to Windows Server 2012 Remote Desktop Gateway?

Hi folks,

We had a Windows Server 2008 R2 server with the remote desktop gateway role installed. How can I migrate the RDG role to a Windows Server 2012 machine?

I did not come across any documentation on this specific operation. We tried exporting the policy and configuration settings, but the XML file was not accepted for import in the 2012 RDG. I tried massaging the XML since there were a few differences, but it still did not take. We didn't see a powershell cmdlet for export/import operations either.

What we wound up doing was to recreate each CAP and RAP rule by hand on the 2012 RDG. Was there a better way to handle this?

Thanks!

User profiles overwritten with new ones after rejoining domian

We had a hard drive failure on this RDS server and after we replace the drive and the raid was rebuilt the server lost its trust relationship with the domain. We had to remove it from the domain and re-add it. We thought everything was fine until the users logged back in. Since we rejoined the domain it created a new profile. But the old profiles are no were to be found. It is like the new one overwrote the orignal. In the past we have seen a second profile folder created. Any one ever seen this?

Thanks

scalability of Windows 2012 TS Solution

Hi, Is there still a need for Citrix or can Windows 2012 now scale to large enterprises with 20,000 concurrent users? Consultants keep telling us Windows 2012 can't but no one seems to be able to say why. Even the Microsoft rep who is the business relationship manager for Citrix didn't seem to even understand what 2012 can or cant do from a RDS point of view. From a broker point of view we have some high end F5s that we can use to scale the connections, I just am trying to work out whether we still need Citrix. Currently Citrix is used to host applications. (no streaming) It would be good to reduce our licensing. Obviously Microsoft present challenges with non Microsoft clients, however beyond that, I would like to understand if we want to move to a non citrix environment if it is possible. Thanks

TS Web & RD Web RDP connection problem

February 18, 2013, 1:52 pm
$

Summary:

  • Problem using Remote Apps & RDP from "RDWeb" interface when accessed from the public internet.

Background:

  • Currently have, 1 x Windows Server 2008 TS Web Access & 1 x Windows Server 2008 R2 RD Web Access setup.
  • Both are configured to use remote apps inc RDP.
  • Both allow login to the web interfaces (Prompts for login when connection to URL).
  • Both allow RDP connections internally and work correctly without problems.
  • Both have Digicert SSLs installed, tested as valid.
  • These are standalone installations and not in a Farm.

Issue:

TSWeb (Server 2008) works correctly and allows RDP connection to itself from the "Remote Apps"

RDWeb (Server 2008 R2) does not and the RDP connection errors:

"Your computer can't connect to the remote computer because the Remote Desktop Gateway server is temporarily unavailable. Try reconnecting later or contact your network administrator for assistance"

I am trying to connection to the RDWeb server externally from a Windows 7 PC (RDP 6.2.9200). If I click the "Remote Desktop" selection on the TS Web Interface, I can also RDP to other Windows Server 2003 terminal servers, however any other Server 2008 R2 servers to not work.

Questions:

  1. Is there something being missed in the configuration?
  2. Are there any fundimental differences between Server 2008 TS Web and Server 2008 R2 RDWeb? (Security etc?)
  3. Would someone also be able to clarify the need to open port 3389 on the firewall, my understanding was that RDP (3389) should be wrapped in the HTTPS (443) traffic therefore only 443 would need to be opened. Unfortunately we have had to allow 3389 on the firewall for RDP connections to function from the outside work and get TSWeb working correctly. I presume I have misconfiguration reading this post: http://social.technet.microsoft.com/Forums/en-US/winserverTS/thread/d5906eb8-9a08-42b0-bdd8-356383401554

RDP signing breaks logon

Hi All!

I've got a strange problem and have tried many things, but I'm not able to fix it...

I've setup a Windows 2008 R2 Remote Desktop Server with Remote Desktop Gateway and Remote Desktop Web and Remote Desktop Licensing, all on 1 machine. Everything worked fine for a few days, but after changing the short time format and copying it to the default and new user accounts, it seems to break the signing of RDP files. Even after changing the short time format back, it is still broken. I've got this problem when I connect from different clients with Windows 8, Windows 2008 R2 SP1 and Windows 7 SP1.

When I disable the RDP signing, I can log on without a problem. But when I try to sign the RDP files, I get an error stating the following:

Your computer can't connect to the remote computer because an error occurred on the remote computer that you want to connect to. Contact your network administrator for assitance.

If I use the C:\Windows\Web\RDWeb\Pages\rdp\Server.rdp file that is signed; I can't connect. If I then open this file with notepad en remove the signing lines, I can connect. So it must have something to do with the signing, but I can't figure it out.

What I've tried so far;

Completely remove the RD Gateway/Web/IIS roles and reïnstalled it > no fix

Exported the SSL cert, removed it from the machine in the Certificate MMC console, imported it again during reïnstall of the roles > no fix

Changed the RDP Security Layer > no fix

Disable and Enable signing > no fix

Any thoughts on this would be appreciated. Thnx!

i want to know the minimum hardware requirements for a thin clients pc to work in our environment. we will be using windows server 2008.

Hi, Everyone.

I've done my first RDS install under 2012 server.  Published apps and got Windows clients working A-Okay.  EasyPrint works for Windows machines.

MAC (OS/X, 10.8.2, using RDC 2.1.1) clients are not redirecting printer(s) using easyprint.  Verified that RDC is configured to "Use a printer that is connected to the MAC".

Anyone got any good hints about where to start troubleshooting this?
