Remote Web Access (remote desktop gateway) issue with WHS2011

I have been using Remote Web Access on my Windows Home Server 2011 for several years with no problems. Over the past several weeks, though, I have been receiving an error when I try to connect to a computer through WHS's Remote Web Access:
"...the Remote Desktop Gateway is temporarily unavailable." Interestingly, when I try to connect from a Windows 8.1 computer, I just get a dialog box that says "Initiating connection," but the connection is never established. I cannot
find any relevant errors in any of the event logs.
I have read numerous articles relating to WHS configuration and port forwarding, but these do not have any information that addresses my situation. I have ports 4125, 80, and 443 forwarded to my Home Server. As I said, everything has been working fine with
this configuration until several weeks ago -- I suspect it might have something to do with a .NET Framework 4.5 update that was recently installed (and that has now been uninstalled), but that is the only change I can think of.
Any help would be greatly appreciated! Thanks!

Hi,
As you have commented that after installing .Net framework you are facing this issue. So after uninstalling still you are facing the same issue. Apart from installing .Net framework 4.5, have you installed or done any other change on your server?
Here you can check that “Remote Gateway Service” is running. Please check and restart the service if it’s stop. Apart you can check below 2 article for more detail step.
1. Can’t connect to the remote computer because the Remote Desktop Gateway server is temporarily unavailable error via SBS 2011
2. This computer can't connect to the remote computer because the Terminal Services Gateway server is temporarily unavailable (Try to perform the steps as suggested for
WHS 2011)
Hope it helps!
Thanks,
Dharmesh

Questions regarding Outlook Web App, Remote Desktop, Remote Web Access and VPN Access

Hi there,
I want to ask a series of questions regarding Outlook Web App, Remote Desktop, Remote Web Access and VPN access and was hoping whether you could help me. Below are my questions to ask you.
Outlook Web App - What do I need to configure in order to get my Exchange account to work with the OWA app on my iPhone? Is Office 360 required on the server that hosts Outlook Web App in our organisation? When I configure the settings and
connect I get the following message "couldn't connect - We couldn't connect to the server. Check your information and make sure it's correct." I can connect with other devices using Outlook Web App.
Remote Desktop - What do I need to configure in order to connect to my computer at work using Remote Desktop on my Windows Phone? When I configure the settings and connect I get the following message "Connection error - We couldn't connect
to the remote PC. Make sure the PC is turned on and connected to the network, and that remote access is enabled. Inquiring minds may find this error code helpful: 0x204" I can connect with other devices using Remote Desktop. There are currently no
RD Server settings in the Remote Desktop app on the Windows Phone and the only way I'm to connect to my PC at work is via Remote Desktop and not to be confused with the one by Microsoft, however the app is on a trial basis and times out every 5 minutes and
can only be used once every hour unless I purchased the app for £2.99 off the App Store but would ideally like to use the Microsoft Remote Desktop app though.
Remote Web Access - What do I need to configure in order to get Remote Web Access on my Windows Phone using a URL? When I log in using a URL I get the following message "There is a problem with this Web page. Please contact the person who manages
the server" I can connect with other devices using Remote Web Access. Also how do you enable the background option for Remote Web Access? I know how to do this in Remote Desktop but not in Remote Web Access. Remote Web Access works on PCs regardless
being onsite and offsite and on my iPhone, the same issue also occurs with my Nokia 5230s regardless of whether I'm using Opera Mobile or Mini or the latest Nokia Browser.
VPN access - How do you configure VPN access on a Windows Phone using VPN? I cannot find the protocols PPTP, L2TP, SSTP and IPsec in order to configure VPN access on the Windows Phone apart from IKEv2.
Many thanks,
RocknRollTim

Any help would be much appreciated.
Kind regards,

Hi,

"Impossible to connect with RWA. Please contact the person in charge of the server"
Did you type RWA URL in IE (or any third-party Browser) and then get below error? Did you access the RWA website
internally? In addition, would you please let me know complete error message that you can get?
Would you please let me know what kind of domain name you use via
Set Up Your Domain Name wizard? When complete Set up Anywhere Access wizard, did you find any error message?
Please refer to following article to check if configure RWA correctly and troubleshoot RWA.

Windows 8 PC not able to remote desktop via Remote Web Access

Windows 8.1 PCs cannot initiate a Remote Desktop session to Windows 7 PCs via Remote Web Access running on Windows Server 2012 Essentials. The Windows 8.1 PC can Remote Desktop to the Windows 7 PC by IP using a VPN, and can connect using
the "Remote Desktop to the Computer" option under Devices in the WSE Dashboard.
All PCs and the server have all Windows updates applied. Specificallly, the Windows 7 PC has KB2574819 is installed and the RDP Policy 8.0 has been activated using local group policy. NLA is not active.
Given that direct Remote Desktop connections work OK but not RDP proxy session, it would appear that the problem has to do with the RD Proxy on Windows Server Essentials.
Is anyone else experiencing this problem? Does anyone have any troubleshooting tips on how to trace this problem down?

Hi,
Please check if there is any error in the remote desktop service log both on the Windows 8.1 client and server sides. You can find the log under Applications and Services logs – Microsoft
– Windows – TerminalServices.
Thanks.

Small Business Server 2011 Essentials Remote Web Access fails to connect to Windows 8.1 PC

I am using Remote Web Access (RWA) gateway with Small Business Server 2011 Essentials.
There are several workstations all running Windows 7, and have been using RWA without an issue for well over a year.
There is now a Windows 8.1 Pro PC added to this domain, but the Remote Desktop does not connect.
The Windows 8.1 PC appears in the RWA pages, It requests the credentials to connect, and then fails with the following error:
Remote Desktop can't find the remote computer "COMPUTERNAME". This might mean that the "COMPUTERNAME" does not belong to the specified network. Verify the computer name and domain that you are typing to connect to.
I can connect to all other PC fine (running Windows 7). I have tried from different locations and PC's and the results are the same.
I thought I had fixed this problem a few weeks back. After running all updates on the server and Windows 8.1 PC, and rebooting both, the RDP worked, but I think it only worked once and then failed the next time someone tried to use it. I have not had
a successful connection to the Windows 8.1 PC since.
I am at a loss on how to troubleshoot this as there are no errors on the system which can't be accessed.
Any suggestions will be appreciated.

Hi Mr Cheese,
à
I turned off the Firewall on the Windows 8.1 PC and the RDP is now working.
Thanks for sharing in the forum. Your time and efforts are highly appreciated.
Based on your description, this issue is related to Firewall. Would you please let me know current situation
of this issue?
Just addition. Please open Control Panel, select Windows Firewall and click Allow an app or feature through
Windows Firewall. Then please check if Remote Desktop is allowed. Meanwhile, please click Advanced settings in Windows Firewall panel and click Inbound Rules, then check if rules which be related to Remote Desktop were enabled.
If any update, please feel free to let me know.
Hope this helps.
Best regards,
Justin Gu

How do I change the URL to the Remote Web Access server in Windows Server 2012?

Hallo!
I have set up a Remote Dexktop Service using the "Quick" deployment method in Server Manager and everything is working greate internally, but I cannot start an app published in Remote Web Access from outside our network.
The problem is that it wants to start the using the internal URL, for example, server.domain.local, instead of the external one, for example remote.server.com.
I therefore want to know how I can change the default URL for the Remote Web Access server and all the Remote Web Apps in Windows Server 2012?
I have allready looked in Server Manager and I can change some of the deployment settings in server manager, but there is no way to alter the URL of the Remote Web Access server. See below images:
Pressing the internal URL only results in opening the internal URL.
This was very simple to do in Windows Server 2008 R2 using the tsconfig tool, but it does not seam to be any way of solving this in server manager.
A possible sollution would be to alter the registry someware in HKLM->Software->Microsoft->Windows NT->Terminal Services. But this can easaly lead to problems due to wrong format, etc. and is probably not supported.
Is there a simpler and supported way?

That option can be used to connect to any machine that you want. The error message indicates that the client machine cannot resolve the name "server.domain.local" to an IP address that it can connect to.
You have several options for configuring that tab on the RDweb site. You can even remove it entirely.
Customization of RD Web Site
RD Web provides a number of customization options for the RD Web interface, including the ability to control default Gateway server settings and redirection settings. These settings
are controlled by editing the web.config file located in %SYSTEMROOT%\Web\RDWeb\Pages.
Displaying Local Help
To display local help for users instead of the web-based help, edit the LocalHelp value and change the value from false to true.

<add key="LocalHelp" value="false" />
When this value is changed, a user that clicks on Help in the upper right corner of the RD Web login page will open the local help file instead of web-based help.
Hiding the Connect to a Remote PC Tab
The RDWeb page
Connect to a Remote PC tab can be hidden from users to prevent connections to any servers through RD Web other than the servers configured in a collection. By default, this setting is set to true and the
Remote Desktops tab is displayed. To hide the tab, set the value to false.

<add key="ShowDesktops" value="true" />
When the value is set to false, a user will not see the Connect to a Remote PC tab when logged on to the RD Web page
RD Gateway Settings
If the Connect to a Remote PC tab is enabled, an administrator can configure RD Web to use a Gateway server when connecting to remote computers. To specify a gateway, edit the below
value with the name of the RD Gateway server:

<add key="DefaultTSGateway" value="" />
The default authentication method for the RD Gateway server can also be configured by editing the following section of the web.config:

<add key="GatewayCredentialsSource" value="0" />
Devices and Resources
By default, only Printers and Clipboard are redirected on connections made using the Connect to a Remote PC tab. If the user clicks the

To configure each specified redirection option to be enabled or disabled by default, edit the following section in the web.config file:

<add key="xPrinterRedirection" value="true" />
<add key="xClipboard" value="true" />
<add key="xDriveRedirection" value="false" />
<add key="xPnPRedirection" value="false" />
<add key="xPortRedirection" value="false" />
LAN Experience Defaults
Windows Server 2012 RD Web Access can display a new user selectable option for optimizing the connection for a LAN experience. This option is displayed at the bottom of the RD Web
page and can be controlled by the administrator using the following section of the web.config file:

<add key="ShowOptimizeExperience" value="false" />
<add key="OptimizeExperienceState" value="false" />
This value is set to false by default, but when changed to true, the following checkbox will display at the bottom of the webpage. The LAN experience
checkbox can also be set as enabled by default.
Each setting can also be modified using the IIS Manager user interface:

Can't connect to computer in remote web access

I am running sbs 2011 essentials and have been able to remotely log in to the remote web access page. Once I get there I can see all the shared folders on the server (and access them) and I can also see the computers available for access (my computer
and the server). I can access the server dashboard by logging in as the server administrator (by using domain\admin) and then in a second login as a user (domain\user "with administrative rights"). However, when I go to logon to the client
computer, I receive the error "Remote Desktop cannot find the computer "client". This might mean that client doesn't belong to the specified network. Verify the computer name and network that you are trying to connect to."
Do I have a DNS problem since I can connect to the SBS 2011 Essentials server?

Hi,
Are you facing issues with all the client machine connection? On the workstations make sure Remote Desktop feature is enabled
Make sure windows firewall service is enabled and inbound rule for allow RDP is enabled.

Windows Home Server 2011, How to Turn off Remote Web Access for Dashboard completely?

I have a Dell Server at my House and i thought it would be a good idea to use it to run a website on so, i set up Apache and get it installed. But then every time I type http://localhost/ it would always Come up with the remote web access! So i thought
ok no problem you can disable that in Dashboard. Well i was wrong when i typed http://loacalhost/ it came up with the Proceed Anyways option but sent me to a Big
Bad GateWay. So what im trying to get at is i need to Fully Disbale that Remote Web access or Set a specific Port so it does not interfere with port 80. So does any one know how to fix this or get rid of this issue?

This one may help.

Can't download files on Android from Server 2012 Essentials Remote Web Access

I have two servers, one with Windows Server 2012 Essentials, and the other SBS 2011. Employees like using Remote Web Access to log in from anywhere and have access to shared folders. It works perfect on a Desktop computer, but when they try to
use their Android tablets or phones, and want to download a file (e.g. a PDF) from one of the shared folders on the server, the download fails. When Microsoft was pushing 2012 they said RWA worked great on mobile devices, do I have to set up something
separately to make this happen?
I've completely disabled the firewall, and have ports 80,443,987, and 1723(just to be safe) all forwarded to the server.
I can log into the RWA site on the android, browse files and folders, but when I select a PDF to download, the download shows as if it's starting, shows in my android notification as if its going to start downloading (Shows MobileDownload www.mydomain.com)
but eventually after a few minutes, will time out and show "Download Unsuccessful".
Network connectivity is fine as I can do this on a Windows Desktop PC using any browser (Chrome, Firefox, IE) and successfully download anything I want.
UPDATE: I found this in the event handler when I tried to download something from a mobile device...

Hi,
Before going further, would you please let me confirm something firstly?
Would you please let me know if all Android devices
encounter this same issue? If you download different type files, will still this issue persists? You can upload a small file (such as a text file) to the share folder, then check if Android device can’t download it.
Based on your description, when logon a desktop computer, you will download files via RWA successfully. Please use the user account which logon computer to logon
the Android device, will still fail to download?
Please check if there has enough free space in Android devices that be used to save download.
When this issue occurred, please check the state of Android device in Dashboard. Besides, I suggest you should run the Best Practices Analyzer (BPA) and fix all
it can find. Then monitor the result.

Computers not listed in Remote Web Access site

I have recently completed a migration from SBS 2008 to Server 2012 R2 with Essentials role
It's gone pretty smoothly but I'm having a problem with the PCs I have re-connected to the essentials server not appearing on the Remote Web Access website (they are shown on the WSE dashboard). Is re-using a computer name that was used in SBS 2008
a problem? Some PCs appear for some users on RWA but when I go into the users settings in the WSE dashboard the PCs don't show up under Computer Access, I only see the server members and 1 PC.
I've tried everything I can think of in terms of removing PCs from the domain and reconnecting with a different name.
It's really frustrating I've reconnected 15 of 40 pcs so far, can anyone shed some light on:
a)When PCs should appear on the RWA site for a particular user?
b)Why PCs aren't listed in the Computer Access tab of a used on the WSE dashboard?
Many thanks in advance.

Thank you for your reply.
I had restarted the server twice before my initial post and that didn't fix the issue.
It has mysteriously rectified itself in the last few days. I could connect to the client via RD Gateway even before the problem rectified itself.
I'm not sure if it's related but all PCs and servers usually show as offline / sleeping in RWA even when they are powered on. On the day the PCs appeared in Computer Access they also appeared as powered on in RWA. They have since reverted
to showing as off\sleeping in RWA.
I will be connecting another batch of PCs in the next week or two so will see how that goes.

2012 R2 Essentials - Anywhere Access will not install. Including Remote Web Access portion.

After setting up 2012 R2 Essentials, I attempted to go through the dashboard's "Set up Anywhere Access" wizard. I was able to configure a domain name successfully on remotewebaccess.com but when the wizard attempted to enable the "Remote Web
Access" feature, the wizard flashes a couple of statuses and locks up on verifying and then the entire dashboard crashes. When I go to the event logs, there is only a mention of dashboard.exe having an exception error. I have also delved into the dashboard.log
file and found the following error where it throws the FATAL crash:
Dashboard.Forms: !!!!FATAL: Dashboard shutting down due to unhandled exception: The 'Get-WindowsFeature' command was found in the module 'ServerManager', but the module could not be loaded. For more information, run 'Import-Module ServerManager'.

---> System.Management.Automation.CmdletInvocationException: Length cannot be less than zero.
Parameter name: length ---> System.ArgumentOutOfRangeException: Length cannot be less than zero.
Parameter name: length
I have launched PowerShell and executed the "Import-Module ServerManager" along with the "Get-WindowsFeature" command and it returns the list of available and installed features. I have also tried rebooting the server and attempting the
wizard numerous times and all attempts result in the same error above. Does anyone have an idea of what could be causing this? I have searched google, bing, and the technet similar questions but none have a solution that will allow me to use the wizard to
enable the Remote Web Access feature.

I had a similar issue, it does appears to be caused by MyMovies 5.
I removed MM5 but the dashboard would still crash after opening the Anywhere Access tab and when it had been running the 'Updating' status for a bit. going through the dashboard log I found that just under the line about the Get-WindowsFeature error was
a comment 'atMyMovies.Common... full error as follows:

There was a couple of line before the fatal error suggesting it could be to do with the remote deskop gateway configuration...
   at Microsoft.WindowsServerSolutions.Common.RemoteDesktopConfig.RemoteDesktopConfigLib.IsFeatureAvailable(String featureName)
   at Microsoft.WindowsServerSolutions.Common.RemoteDesktopConfig.RemoteDesktopConfigLib.CheckTSRelatedRolesAvailable()
   at Microsoft.WindowsServerSolutions.Connectivity.Jobs.TsGatewayDiagnosticsJob.OnRun(DiagnosticsResult result, ConnectivityEnvironment environment)
   at Microsoft.WindowsServerSolutions.Connectivity.DiagnosticsJob.RunAndCatch(DiagnosticsResult result, ConnectivityEnvironment environment)
So I ended up removing the role using server manager, along with the remote access role, and then rebooting the server. I then added the Remote Access role back in by choosing the 'DirectAccess and VPN (RAS)' option.
When I then ran the dashboard Anywhere Access setup it worked.
Other issues that seemed to cause the dashboard to crash was when I released the remotewebaccess.com domain name and then added it back in. I had multiple certificates with the same name which seemed to cause an issue. so I released the domain name again,
went into the certificates MMC and removed any of the goDaddy certificate. then configured the domain name again and the rest of the wizard ran with no issues.
Hope some of this helps...

SBS11 Remote Web access from Mac to PC Windows XP

Recently converted from being a PC user to a iMac.
Working on the iMac at home, I need to be able to connect remotely to my PC at work (Windows XP).
Previously been able to do with via our SBS11 Remote Web Access page, but opening in Chrome (on the Mac) it does not connect.
Have downloaded the new Mac 'Microsoft Remote Desktop' App - but am having trouble configuring the settings.
Remote Desktop Setup > PC Name - is this the Public IP of my work PC
> User Name - is this simply my work username
MRD > Preferences... do I need to setup a Gateway?

Hi,
The settings of the App depends on the remote desktop solution used in your Office.
Meanwhile, you can try to access the RD web access site from a Windows client, download the .rdp file and copy the settings.
Thanks.

Remote web access gives critical error on log in

SBS 2011 Essentials does set up the domain when using the custom domain at remotewebaccess. Now however, when I try to log in on the website it gives me this error: Cannot connect to Remote Web Access. Contact the person who manages the server. Remote
Web Access is enabled for all accounts, and I have tried to log into several of them but get the same message.
Jeremiah Doggett

OK... time for more information about your setup.
What router are you using?
Is there more than one router on the network (including a modem-router if this is a DSL Internet connection)?
What is the OS of the external computer through which you are trying to access RWA?
What are the OS(s) of the network computers at the office?
>>Ok, just created a test user with admin rights, I can still login to mobile site, but on the desktop version I get the same error!
So, using an external computer (not an IPhone), you can successfully log into RWA but cannot access (remotely control) any workstations on the network?
Are you getting any certificate errors?
Is 'Remote Desktop' enabled on each network workstation?
And maybe check out this thread: (turned out to be a permissions issue for the original poster)

Error in Remote Web Access - "An unexpected error occurred. Please try again. If the problem continues, contact the person who manages your server."

I have set up the RWA and I can log in to the web console with my server account. However when I click on any of the shared folders I get this error:
An unexpected error occurred. Please try again. If the problem continues, contact the person who manages your server.
Does anyone know how to troubleshoot this?

I had this very same issue with one of our customer's servers that was running Windows Server Essentials. I ended up calling Microsoft about the issue. I hope this helps someone. This originally appeared on my blog: http://techspeeder.com/2014/01/14/remote-web-access-error-an-unexpected-error-occurred/
Troubleshooting Steps:
1. We were getting unexpected errors while accessing shared folders remotely
2. The tech found IIS handlers were missing
3. She went to IIS > server level ( parent level) and added managed handler mapping :
Name: svc-Integrated-4.0
Request path: *.svc
Executable: System.ServiceModel.Activation.ServiceHttpHandlerFactory, System.ServiceModel.Activation, Version=4.0.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35
4. Added script mapping:
Name: svc-ISAPI-4.0_64bit
Request path: *.svc
Executable: windir%\Microsoft.NET\Framework64\v4.0.30319\aspnet_isapi.dll
Name: svc-ISAPI-4.0_32bit
Request path: *.svc
Executable: windir%\Microsoft.NET\Framework32\v4.0.30319\aspnet_isapi.dll
5. Ran IISreset.
6. We were able to access resources in Remote access, then.

Map a drive to the Remote Web Access - Shared Folders

All companies love Remote Web Access. No need for VPN for access to remote desktop and the "private skydrive" Shared Folders.
Is there anyway to map a drive to these "private skydrive" Shared Folders? you can map a drive to the real skydrive and to Sharepoint so surely it is possible?

The trick that I found was to upgrade my file server to server 2012 R2 and configure iSCSI Target for the resource I wanted to access by RWA. On my RWA Server I then used the iSCSI initiator to connect to that Target. This makes the shared drive appear
as if it is a native drive on the RWA server. Once this was done I configured that drive, or a folder within that drive for access with RWA. It has worked perfectly ever since.
Trust but verify!
