RDP Client hanging at "Securing remote Session"

Hi Forum,

I running an RDP Client on W2k8R2 machine - when connecting to target machines higher than W2k8 the RDP Client hangs for about 30 seconds at "securing your Session".
At network dumps I see that the client is asking "ctldl.windowsupdate.com" getting back the IP and trying to connect at TCP/80. The guy seems search for some updatestuff..
The firewall is configured to drop the packages instead of rejecting them - which is causing the 30 seconds delay.

To fix the rootcause - how to disable this update behavior? Seems to have something to do with new implemented rdp certificate authentication?

Thanks for your help in advance,

Andreas

ToKe paged pool tag consuming high amount of memory

Windows 2003 server, sp2.  4GB of RAM

every 3-4 weeks the server runs out of resources, event id 2020.  Paged Pool memory full.  Causes server to become unresponsive.  Users cannot RDP to server. On 11/26, I noticed spoolsv.exe had 106K+ handles and 908K of PPM.  I checked my poolmon logs which run every 3 secs and found the ToKe paged tag consuming the highest amount of PPM.  I cycled the printer spooler service and PPM was released from ToKe tag and spoolsv.exe went down to 254 handles, 84K of PPM.  On 11/26 after this event, I installed the latest HP universal PCL6 print driver too.

I have searched the internet to find a root cause for this issue and can see others having this issue but no resolution has been listed.  Can anyone explain why this is occurring and the relationship between the spoolsv.exe and ToKe paged pool tag?

Thank you

Certificate error when accessing VDs through RD Gateway on Win. Server 2012

February 27, 2013, 12:39 pm

I’m having issues accessing virtual desktops (VD) through the Remote Desktop Gateway (RD Gateway). The main problem revolves are certificates (security?). When a client tries to remotely access a VD, their computer won’t allow them because an error says “This computer can’t verify the identity of the RD Gateway “vd-host.misoit.edu”. It’s not safe to connect to servers that can’t be identified. Contact your network administrator for assistance.” and gives them no options just to ignore the warning.

 

Background:

I am trying to create a VDI environment from scratch for laboratory purposes (not production).

 

Setup:

I have 2 computers with the following OS and roles installed on them.

 

PC 1 (hostname = dmn-ctrl)

-Win. Server 2012 Standard (x64)

-DNS

-AD DS [promoted this PC to domain controller, domain = misoit.edu, made a few users with admin. rights]

_

PC 2 (hostname = vd-host)

-Win. Server 2012 Datacenter (x64)

-RD Services (RDS) [this service installed the following]

-HyperV

-RD Virtualization Host

-RD Session Host

-RD Connection Broker

-RD Web Access

-RD Gateway (this one I had to manually enable, which is where the problem started, everything worked fine before I did this)

 

I have a standard router/switch. I have successful set up port forward to remote into the one of the servers from outside the network using RD Connection (Win7 software).

 

VDI configuration

-HyperV: I have created a VM of Win8, joined it to the domain, sysprep it, and used it as a template to make VDs in a pool (under RD Services -> Collections).

-I can locally go to a browser and access a VD through there. It seems that it automatically runs RD Connection when I click on the link in the browser.

RD Gateway Config

-Server name: vd-host.misoit.edu

-Login method: Password Authentication

-“Use RD Gateway credentials for remote computers” checked

-“Bypass RD Gateway server for local addresses” unchecked

 

The problem came when I decided to install RD gateway to allow access from outside the network. During the installation, I ran into a road block with creating the certificates (SSL?). I made a self-signed one and assigned it to all the RD Services listed above. They ended up all being labeled as “untrusted”. Now when I locally connect to the VD, the error mentioned above happens. If I turn off the RD Gateway, then everything works again.

 

I tried messing around by installing AD CA to pass out certificates, but that was a mess and a new subject I didn’t want to hit hard on (yet). Do I even need the RD Gateway to access VDs from outside the network if I strictly use direct IP Addressing in the browser? I can remote in, but not sure if I can access VDs the same way.

 

Any input would be much appreciated!

Remote Desktop Now Disconnects Wireless Connection

I have two computers running XP Pro. The desktop is using a wired connection to my home network and the laptop uses a wireless connection. For nearly a year, I have been able to use Remote Desktop to control the laptop from the desktop. In the past month or so, this has changed.

Now, when using Remote Desktop to connect to the laptop, the wireless connection is dropped. Logging manually back in on the laptop resets the wireless connection, but this is consistently dropped each time I try using Remote Desktop. I need this facility since the laptop is used to control some equipment remote from desktop.

The desktop is able to connect and control a wired connection to a new Vista Ultimate machine, so I don't think there is anything wrong with it.

The only software changes to the laptop has been whatever Windows updates that have come through. Does anyone have any idea how I can get my Remote Desktop to work once again?

HP Thin Client can't access Windows Server 2008 R2

We bought some HP Thin Client t410. I setup the Thin Client and connect to one of our Windows server 2008 R2 RDS. It worked for a week. I am back to the office after the new year, it can’t connect to the same RDS. Here are details.

  1. If I try to connect the  Windows 2008 R2 RDS (no matter using IP, FQDN), I get this message: “RDP client error: Reboot necessary. The firmware has experienced a critical error”.
  2. The HP tech support recommends me to download the new image Z5A42019 to replace Z5A41204. But that doesn’t fix the problem.
  3. If I use the Thin Client to access other Terminal Servers, it works fine.
  4. I also try another Thin Client, but get the same error.
  5. All our XP and Windows 7 access the same Windows 2008 R2 RDS don’t have this issue.
  6. The RDS Event Viewer doesn’t have any related errors.
It seems to me only the Thin Client connecting to this Windows 2008 R2 RDS has this issue. I think it could be the security issue, but can’t figure it out.

Remote Desktop Farm Issues

February 26, 2013, 3:40 pm

Hi there,

I'm setting up a remote desktop farm.  Here's my general config:
-All servers running Windows Server 2012.
-Three domain controllers, configured for a domain named internal.domain.org.
-Three remote desktop session host servers.
-One server hosting RemoteApp and the Remote Desktop web service.
-One Remote Desktop Gateway server.
-One Remote Desktop Connection Broker server.

The three Remote Desktop Session Host servers have been combined into a collection named "Farm" and there are three DNS records for Farm - one pointed to each of the servers' IP addresses.  The Gateway server has been left at the defaults for CAP & RAP policies for now, which allows all users in the Domain Users group to access all resources on all Domain Computers.

A wildcard certificate has been purchased for *.internal.domain.org, which is what we're going to use for addressing the remote desktop farm both internally and externally.  The wildcard certificate was applied using Server Manager to all four of the functions listed under the Remote Desktop certificates config (RD CB Signing, RD CB Publishing, RD Web Access, RD Gateway) and I have also manually installed it to the three remote desktop session hosts, using Certmgr.msc to put it in the Local Computer Account's personal folder, mirroring the automatic configuration that Server Manager did for the Gateway & Connection Broker servers.

Now, on to the issues:

First, when I try to connect internally to the session hosts, I *have* to use the farm name.  If I try to use a single RDSH server name, it pops up an error saying you must use the farm name.  That's all fine - redirection happens correctly, etc.  However, when I try to connect from outside using the gateway, the exact *opposite* happens - it refuses to connect to the farm name, but will connect to individual servers, and appears to be doing the redirection correctly as well.  The thing is, I don't want people putting in individual server names - I want the farm name to work when they're connecting through the gateway.  How can I make that happen?

Second, when I connect internally to the farm name, it redirects to one of the RDSH servers, but then pops up an error saying the "certificate is not from a trusted certifying authority" even though the wildcard SSL certificate is installed on all of the servers.  When I view the certificate, it's definitely not the wildcard cert - it appears to be the self-signed cert that was generated by the RDSH server.  This error does not occur when connecting through the gateway.  What can I do to make this error go away?

Third, when I add the RemoteApp feed URL to Control Panel\RemoteApp and Desktop Connections, it asks for credentials to add it - even though I have the default credentials (and default credentials for NTLM) settings in group policy set to allow the delegation of credentials to the RemoteApp server.  Any way to get rid of this?

Fourth, once I add in those credentials and add the RemoteApps - I click to run one of the apps in my Start Menu, and I get a warning asking if I trust the publisher of this RemoteApp program.  Again - the SSL cert is installed on the RemoteApp server, so I don't understand why I'm continuing to get these errors.

Fifth, from outside and coming through the gateway, I get the same error as above in #4, but then am prompted to enter credentials again (apparently for the Broker server), and then am denied a RemoteApp connection with the message "Your computer can't connect to the remote computer because a security package error occured in the transport layer."

Any help with any of these is much appreciated.  Thank you!

Server 2012 RDGateway SSO and SAN certificates

I know this topic has been beaten to death but the sheer amount of posts makes it difficult to decipher the fix.

Background:

Windows Server 2012 RDS infrastructure

*Gateway/Web Access/Licensing/Connection Broker roles on 1 Server 2012 VM

-Gateway configured with options:

  • Use these RD Gateway server settings | server name: scottapps.com
  • Logon method | Password authentication
  • Use RD Gateway credentials for remote computers - enabled
  • Bypass RD Gateway server for local addresses - enabled
  • 3rd party SAN certificate (GoDaddy) with name "*.scottapps.com" installed and enabled for all role services (RDCB - enable single sign on; RDCB - publishing; RDWC; RDG)

*Session Host role installed on 3 separate VMs (each a separate VM running Server 2012)

*3 Remote App collections published (each going to their respective server)

*BYOD scenario - clients running Win7/Win8 connecting to RD Web. Working from home, offsite, etc.

2 issues:

*Being prompted twice for credentials - once when logging into RD Web (of course) and then again once a Remote App is selected. Not prompted twice internally from other server 2012 boxes joined to the domain. This leads be to believe if I used Win8 it wouldn't happen? http://blogs.msdn.com/b/rds/archive/2012/06/25/remote-desktop-web-access-single-sign-on-now-easier-to-enable-in-windows-server-2012.aspx

*Getting the "the identity of the remote computer cannot be verified..." warning. Not sure how to fix this since the internal name of the servers is xyz.local and the name of the SAN SSL cert is *.scotapps.com

Thanks!

Howto configure RDS connection broker for non-virtualised personal desktops

Hi

I have an RD Session Host farm configured with a clustered connection broker.  This works fine, providing load-balanced RDS sessions (Terminal Server Sessions) to domain users.

I also have a number of domain bound physical hosts, running legacy applications. I would like to assign these physical machines as "personal desktops" to some specific users. I have setup another RDS host, made it a member of the connection broker cluster, and set its mode to "Virtual Machine Redirection".  How can i specify machines to redirect-to without using a Hyper-V server?

Since these are physical hosts they are not running on Hyper-V, nor can i virtualise them.

I have seen the account properties in AD for assigning the FQDN of a host to a user, but i do not know how to configure the RDS host for this purpose. 

Any help would be appreciated.

We have a centralized License server (Windows Server 2008 R2). The License Server hosts licenses for all our applications as well as RDP-CALs.

Since we are now planning to migrate the License Server unto Windows Server 2012, can we still host Previous Windows versions RDP-CALs (W2K8) on the new 2012 server.

NLB and RDS Server Farm

March 4, 2013, 7:44 am

Setting up a Windows 2008 R2 Remote Desktop Services environment and I'm getting stuck on my server farm config.

RDC Broker is installed to a domain controller at 192.168.1.12

I have 3 RDSH servers I want to add to the farm using network load balancing.  All 3 have that role installed as well as the NLB feature and dual NICS, the individual host IP's are 192.168.1.31, 32, 33 corresponding to node1, 2, 3.

NLB is setup, all 3 nodes are added and converged.  I created a DNS A record for the cluster nlb.domain.local 192.168.1.40

On each cluster host I configured the TS farm as follows:

RD Connection Broker Settings:

Farm member

RD Connection Broker points to the DC above

Farm Name: TS-Farm...?

RD Connection Broker Properties window:

Settings listed above are on top....

Participate in Connection Broker Load-Balancing

Use IP address redirection

IP to use for redirection: Node1 192.168.1.31; Node2 192.168.1.32; Node3 192.168.1.33

My question, referenced above, what should I use as the farm IP address?  Do I create three A records for ts-farm.domain.local, using the addresses of 192.168.1.31-33?

Do I point a ts-farm DNS entry to nlb.domain.local which is .40 my cluster IP?

I think that covers it all....thanks in advance!

**Edit**

DNS round robin is not an option in this setup.  Thanks.
