Unable to launch applications from RD Web
-
Thursday, November 29, 2012 5:58 PM
I have set up a 2012 Hyper-V server that is not part of the domain and a 2012 DC as a virtual machine and 2012 application server as virtual machine. I have setup RDS on the application server. I am able to connect through RDP and launch applications fine but this gives too much access to the user. I can connect through RD Web by https://xxx.xxx.xxx.xxx/RDWeb but when trying to launch any of the published applications, I get an error that states "The remote computer could not be found. Please contact your helpdesk about this error."
What is missing here? Any help would be greatly appreciated.

Do a simple test. Can you launch the remoteapp in the RDS? Or you may you try to check WMI rights or reboot the RDS. This post may help too.
RemoteApps not populated in RDWeb because of WMI rights ...
It stopped happening for me, but I do not recall that i found a "fix". Could be your WMI repository had issues and rebuilt automatically, causing ... are gone, even though the "TS Web Access computer group" is still populated.

I tried the recommended setting for WMI from your link. There wasn't a "TS Web Access Computers" group. I added the "Domain Users" group to this and added the same permissions for testing purposes and this didn't resolve the issue. There wasn't a certificate created for RDWeb so I created a self signed certificate but this didn't resolve the issue either.
Regarding the test. The remote applications do launch when connected strictly through RDP on port 3389.
What else could be the issue?

Friday, November 30, 2012 2:54 PMDo you have any errors in the Event Viewer on the RDS when attempting to open remoteapp?

Friday, November 30, 2012 3:00 PMNothing in event viewer regarding RDS and the http event is when I created a certificate. This happens on the internal LAN and external WAN as well. Do you think that I need to set an HTTPS binding in IIS?

Friday, November 30, 2012 3:02 PMThe error message is generic basically means that the client tried to connect to <servername> but either could not resolve that name to an IP address or could not connect on port 3389 to that IP address. If you can read network captures, I would start by taking a capture and verifying if the client is able to make a TCP connection on port 3389 to <servername>.

Correction. I did find this Event buried.
Event ID: 97
Level: Warning
User: Network Service
OpCode: ProtocolExchange
Task Category: RemoteFX module
The RDP protocol component X.224 detected an error (0) in the protocol stream and the client was disconnected.

Ironically now I am not able to connect with RDP either.
I get the following Event:
Event ID: 101
Level: Warning
User: Network Service
OpCode: Network Detect
Task Category: RemoteFX Module
The network characteristics detection function has been disabled because of Client not supported..

Ok. I totally removed IIS and RDS from the server and reinstalled. I installed RDS this time without using a gateway. I can get RDWeb applications to launch internally when putting the FQDN in the address bar. https://servername.domain.local/rdweb
Obviously, externally I can't do this. It seems to be a DNS issue if I am not mistaken. Any recommendations?

If you can access remoteapp internally, but not from the Internet, it could be DNS issue or RD Gateway issue.
1. From the Internet, can you ping the remoteapp server internet domain name? Can you telnet port 443?
2. If above works fine, you may need to configure RD Gateway. These links may help:
