MS Remote Desktop Connection through Self Service

This appears to be possible according to Microsoft's documentation:

https://docs.microsoft.com/en-us/windows-server/remote/remote-desktop-services/clients/remote-desktop-uri

Using the sample command from that page, you could add the following one-line command to a Policy under Files and Processes > Execute Command and then enable the policy for Self Service.

/usr/bin/open rdp://full%20address=s:mypc:3389&audiomode=i:2&disable%20themes=i:1

Interestingly, those URIs work as regular Self Service bookmarks. I just added something like the above to my Self Service bookmarks list, with it set to open in a browser, not in Self Service, and when it's clicked, it auto opens Microsoft Remote Desktop 8 or 10, whichever is installed.

OTOH, you could do the Execute Command > open in a policy, or you could even export the links out from RDP into .rdp files that you can package up and push out to devices into a specific folder on them. The last one might be useful if you have a large amount of rdp links you need users to have.
So, multiple ways to address this.

Just make sure if you will be using Execute Command via policy to put backslash() before ampersand(&), like this:

/usr/bin/open rdp://full%20address=s:mypc:3389&audiomode=i:2&disable%20themes=i:1

I do use a script to push an RDWEB feed, but it's still a tad flaky.

Here is what i Have

Parameter 4 = Feed URL ( eg https://dnsnameofserver/RDWeb/Feed/webfeed.aspx )
Parameter 5 = Authentication ? NONE / USER / SPECIFIC
Parameter 6 = Specific Username
Parameter 7 = Specific Password

Script is
