CC4 - Accessing RemoteApps not working (after pointers really)

[mcrompton01]

Hi all,

 

I'm having an issue with a published remote app at one of newly joined MAT schools, they are CC4 and i have zero experience of it so I'm not sure where to start. Our parent MAT school has a published a series of RemoteApp for other partner schools to connect to (mainly management apps), these work in 3 our 4 MAT schools perfectly fine. However this one school it does not work the issue is:

 

1. You can visit the RemoteApp website, login, see a list of App, download the RDP file, run the file, prompts of username/password, (on incorrect entry it will throw an error so we know thats working), finally the error is displayed "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"

 

2. You can add the RemoteApp via the control panel, it appears in the startmenu, again then you click on the shortcut the following message is displayed: "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"

 

3. This system works in 3/4 schools fine, the accounts are identical in settings, groups, etc and from multiple other locations (home, other school, mobile apps) it all works fine.

 

We have tried the following but cannot think of anything else:

 

1. Enable remote desktop connection in the GPO (CC4 school)

2. Tried 3 different proxy servers available (we have 3 in total to use one is SmartCache, the other two are county level servers with 0 authentication)

3. the events logs on the RDS Gateway show the user connecting and disconnecting in 1-2 seconds

4. Windows firewall if off

5. Updating to RDP 8 and 8.1

6. Using a mobile app on a phone connected to their wifi works

 

Sorry OS Windows 7 SP1 fully updated.

 

I'm stumped, has anyone got any suggestions.

Have you checked you internet filtering logs and firewall to make sure the relevant URLs aren't being blocked and you have the appropriate ports open, if it is Citrix I believe ICA needs ports 1494 and 2598 to be open.
