Right now I have only have 10 Windows 10 VMs spun up.

Problem #1: At seemingly random intervals, users are unable to connect to their VM via their physical Wyse thin client terminal. After logging in, the client contacts the broker, attempts
to sign into the machine and then says «RD Failed». After rebooting the broker server things go back to normal for a few hours, then the «RD Failed» messages return again.

The weird thing: everything works fine if they try to connect from RD Web Access.

Problem #2: Again, at seemingly random intervals, users are receiving messages when logging into their terminals saying: «The requested session access is denied.»

The weird thing: this is only sometimes, and usually goes away if they either a) leave the error message on their screen or b) exit and try again.

I’m honestly not sure where to go from here. I thought it could be a policy or permission issue but it only does it sometimes?

Microsoft TMG 2010 RDS Publishing issue

Некрофилии пост. Словил забавный глючок на доживающем свое Microsoft Forefront Threat Management Gateway 2010. Развернута у меня внутри сети инфраструктура удаленных рабочих столов с блэкджеком и т.п. Доступ в сеть через Remote Desktop Gateway. Там тебе и CAP и RAP, все по-серьезному. И все это дело (RDGW в смысле) публикуется наружу через TMG. Классика жанра для 2008 года 🙂

Во время выполнения довольно ответственных работ по перенастройке инфраструктуры RDP, было создано временное правило, публикующее внутренний management-server (ну отдельный сервер для администраторов со всякими консолями и прочим) на одном из внешних интерфейсов. Правило выглядело безобидно:

Allow TCP 3389 from Remote Management Hosts to Management Server via External Network Adapter with IP-address 10.10.10.10

Т.е. становится понятно, что это обычное правило публикации. Оно работало, серверы RDS чинилисьпереконфигурировались. После их починки началось странное: нельзя было подключиться к серверу TMG с использованием RDGW. Причем сам сервер RDGW писал в логе:

Description: The user «COMPANYO.Krylov», on client computer «192.168.1.2», met connection authorization policy and resource authorization policy requirements, but could not connect to resource «tmg.company.ru». Connection protocol used: «RPC-HTTP». The following error occurred: «23005».

Попытки подключиться к TMG непосредственно с серверов RDGW так же оканчивались неудачей с невнятными комментариями.

Что делает настоящий айсавод? Правильно, проверяет IP-адреса серверов RDGW (те, кто не в курсе, как работает Remote Desktop Gateway, просто имейте ввиду, что подключение к серверу выполняется именно с них по TCP3389, проксируя подключения к ним по TCP443), лезет в консоль TMG и смотрит две вещи:

System Policy в разрезе Terminal Services (включено ли, каким группам разрешен доступ)

Группы Remote Management Computers и Enterprise Remote Management Computers.

А там все в порядке 🙂

Что же, что же за глюк-то приключился? А приключилось вот что… Если набрать в командной строке Netstat /ano видим, что TCP3389 слушается ТОЛЬКО на 10.10.10.10 и не слушается ни на одном другом адресе. Окей, TMG! Убираем временное правило публикации RDS. И… Тот же результат. Рестартим сервисы Remote Desktop Services и Remote Desktop Services UserMode Port Redirector и видим, что теперь TCP3389 слушается на всех интерфейсах.

И это еще не все. Идем в оснастку Remote Desktop Session Host Configuration, выбираем в списке Connections то, что нам нужно (а скорее всего там будет один объект), в его свойствах на вкладке Network Adapter выбираем внутренний интерфейс и еще раз рестартим службы Remote Desktop. В итоге вы получаете возможность подключаться по RDP к серверу только из внутренней сети, хосты которой ограничены членством в группах TMG Remote Management Computers и Enterprise Remote Management Computers.

Question

I am tearing my hair out. I have a RD Gateway server that is pointing towards a RD Farm. I cannot connect to it using the Gateway. I keep getting the the following error in the TerminalServices-Gateway Operational log:

Log Name: Microsoft-Windows-TerminalServices-Gateway/Operational
Source: Microsoft-Windows-TerminalServices-Gateway
Date: 10/7/2014 10:56:02 AM
Event ID: 304
Task Category: (3)
Level: Warning
Keywords: (16777216)
User: NETWORK SERVICE
Computer: XXXXXXXXXXX.wbc.local
Description:
The user «XXXXXX», on client computer «XXX.XXX.XXX.XXX», met connection authorization policy and resource authorization policy requirements, but could not connect to resource «SyteLine.wbc.local». The following error occurred: «23005».
Event Xml:

Any ideas? Lots of googling has not helped

Answers

If you log on locally to the RD Gateway server and open mstsc, and you able to successfully connect to syteline.wbc.local?

You may want to use netmon/wireshark to capture the traffic between the RD Gateway and the target RDSH server and see if you can see what is happening when you attempt to connect.

Thank you for posting in Windows Server Forum.

To resolve this issue, ensure that Remote Desktop is enabled and that the user is a member of the Remote Desktop Users group on the target computer.

Please check that you have properly configured RD CAP and RD RAP policy for RD Gateway server. For remote clients to successfully connect to internal network resources (computers) through a Remote Desktop Gateway (RD Gateway) server, clients must meet the conditions specified in at least one Remote Desktop connection authorization policy (RD CAP) and Remote Desktop resource authorization policy (RD RAP).

The farm is accessible inside the LAN — it’s the Gateway that is not working. The error message states:

The user «XXXXXX», on client computer «XXX.XXX.XXX.XXX», met connection authorization policy and resource authorization policy requirements, but could not connect to resource «SyteLine.wbc.local». The following error occurred: «23005».

So it looks like the RAP and CAP is working correctly

For future searchers.

I had this issue also. I was able to fix this by enabling the Remote Desktop setting in Server Manager > Local Server (on Windows Server 2012 R2). I verified that the connection is going through the Gateway using RD Gateway Manager.

I deployed a new collection of Windows10 VDI machines, initially I could connect and all was fine.

But after some time it reverted to its local policy of not allowing inbound RDP connections, so I just had to put in a new GPO to always allow RDP connections to virtual machines.

I was also pulling my hair out over this error. Almost all week. And at around the same time a number of other problems appeared, which all seemed unrelated.

When using RDWeb over the internet, and connecting to a resource (Session Host or VDI) on a separate server to the Connection Broker / Session Host (one server doing both), it would give the user an error and RD Gateway would log Event ID 304 with error 23005.

What I found was that a policy I set in place across all domain computers was the cause.

Computer ConfigurationWindows SettingsSecurity SettingsLocal PoliciesSecurity Options
Network security: Restrict NTLM: Outgoing NTLM traffic to remote servers

This was set to Deny all. And I then found these logs:

Event Log: NTLM
Event ID: 8001
«NTLM client blocked: Outgoing NTLM authentication traffic to remote servers that is blocked.
Target server: TERMSRV/ «

After changing that policy to Audit all everything worked again.

Вопрос

We have a simple setup here but we have a problem with users have intermittent connection issues. The event log isn’t the most helpful so I was wandering if anyone here can point me in the right direction. In lamens terms this is my issue.

We have a Kemp load balancer to two RDS gateways and then our RDS connection broker then our RDS hosts. All are Windows Server 2016.

Daily we get issues from remote working users that when they first connect they get the configuring connecting dialog box (after all the authentication) and it just stays there and either times out or the user just cancels. When they click on the RDP icon and attempt to connect a second time, it works fine and logs straight in.

I understand there are many factors (user internet connection etc) but we (IT) have ourselves, in the evening gone home and tested it and get the same issue. spinning circle on configuring, cancel it or wait until it times out, try again and straight in.

Is there anywhere you can tell me where I can look like a RDS log where I can see exactly what it is doing so I can get to the bottom of this issue?

On a side note I can see in the «TerminalServices-Gateway» log on one of the gateway servers, I keep seeing this warning and error (same time) against a mixture of users, daily;

Warning: The user «domainuser1», on client computer «IP address», met connection authorization policy and resource authorization policy requirements, but could not connect to resource «RDS Host 4». Connection protocol used: «UDP». The following error occurred: «23005».

Error: The user «domainuser1», on client computer «User IP address», failed connection to the remote server «RDS Host 4» using UDP proxy. The following error occurred : «2147965405».

Now, I dont know if this is related to what everyone is experiencing but it doesnt show this error and warning for everyone who has the two attempt connecting issue. I just put that in to see if it helps.

I just want to know if there is anywhere I can see exactly what is happening when connecting (RDS logs etc).
