Remote Desktop Open File Warning

Question

Remote Desktop Open File Warning

Alan Benet 40

Hi

We have a Host Pool with some VMs. We also have a Application Group with our Application associated to it.

The Application is a .exe file on a Azure File Share.

Now to my issue:

When I use the RDP file and open the whole Desktop and start my App trough the UNC Path, I don't get any Warnings.

But when I start the same Application trough the Remote Desktop App I get the Open File Warning.

Is there any reason why when using the Remote Desktop App I get the Warning and when I start the Application trough the Desktop itself the Warning doesn't show?

I already added the file path and URL in the Internet Options. I even tried to Enable the settings that opening files from an extern location shouldn't cause any warnings.

I also tried to set it in the GPO.

Did anyone have the same issue and knows why it behaves like this?

@Alan Benet To understand the issue better can you please elaborate bit more on your query.

I assume this issue is not related to Azure files, can you please share the warning message screenshot? This warning message may be a security feature of Windows that is designed to protect your computer from potentially harmful files that are downloaded from the internet or other external sources.

To avoid this warning message, you can try adding the file path and URL to the Trusted Sites list in Internet Options. You can also try enabling the settings that allow files from external sources to be opened without warnings. Additionally, you can try setting it in the GPO.

If none of these solutions work, you can try disabling the warning message altogether. However, this is not recommended as it can compromise the security of your computer.

Additional information :

Here are some steps and considerations that might help resolve the issue:

Check the Application Group Settings: Ensure that the application group settings in Azure Virtual Desktop are correctly configured to trust the file share where the .exe is located.

Review the GPO Settings: It's possible that the Group Policy settings might not be applying correctly to the Remote Desktop App sessions. Revisit the GPO settings to ensure they are correctly configured and propagated to the user sessions.

Update the Remote Desktop Client: If you're using an older version of the Remote Desktop client, consider updating to the latest version, as there might be fixes related to security warnings.

@Sumarigo-MSFT Thanks for the reply!

Here the Warning:

For the GPO I Enabled under: Local Group Policy Editor => Computer Configuration => Administrative Settings => Windows Components => Internet Explorer => Internet Control Panel => Security Page: I Enabled: Site to Zone Assigment List

On the User itself I added the UNC Path and the URL Path in the Local Intranet settings.

Could you give me some Details on the Application Group Settings?

I tried to look into it and search it on the azure but couldn't find anything.

What I missed to mention is that we created a shortcut of the .exe on the vm and we referencing the shortcut (.lnk) in the application group to start the app on the Remote Desktop App.

After trying this I still get the same issue only over the Remote Desktop App.

Hi , Welcome to MS Q&A

I think it seems that the Open File Warning you're encountering when starting an application through the Remote Desktop App could be related to file redirection settings. When you connect to a remote session through the Remote Desktop Web client, you have the option to allow the remote computer to access local resources such as files, printers, and the clipboard on your local device. If file redirection is enabled, files opened in the remote session may be redirected to the local device, which could trigger an Open File Warning when the application is started.

For more information, you can refer to the following Azure documentation:

As these are some general troubleshooting steps, please let me know if you have any further questions

We can deep dive and check in details

Kindly accept answer if it helps
