What this article covers

GreenLoop RDP Connect is the portal at rdp.greenloopsolutions.com, and it is where you collect the connection files for the remote computers you have been given access to. You sign in with your own work email address, you see the machines assigned to your account, and you download a ready-made .rdp file for each one.

This guide covers the invitation email, the first sign-in, and the download itself. Keep in mind this is just a portal for downloading the RDP file itself, so this guide does not cover using the RDP connection since that will remain unchanged.

Why GreenLoop RDP Connect?

An .rdp file is a plain text configuration file. It names the computer to connect to, and it also decides which parts of your local machine are handed to the far end — your drives, your clipboard, your printers, your microphone. Because the file is only text, anyone can write one and email it to you, which is exactly what attackers have been doing. Windows now inspects every .rdp file you open and asks you to approve it.

The portal answers that problem at the source. Every file it produces is digitally signed by GreenLoop before it reaches you, so Windows can tell you who authored the connection and confirm that nothing has been altered in transit. The settings inside the file were chosen by an administrator rather than pasted in by whoever sent it. And because the list of who may download what lives in one place, access can be granted, changed, or withdrawn without anyone re-sending files.

For the full background on the Windows prompts and why they appeared, see The April 2026 Remote Desktop Update: Understanding RDP Signing and Your Options. The short version is that unsigned connection files now carry a red “unknown publisher” caution that cannot be dismissed permanently. Signed ones do not.

Your Invitation

Access starts with an invitation. When GreenLoop adds you to the portal, Microsoft sends you a guest invitation email at your work address, and you accept it once. That acceptance links your existing work account to the portal — it does not create a new password, and there is nothing extra to remember.

Open the invitation and select Accept invitation. You will be asked to sign in with your work account, and you may be asked to approve a one-time consent prompt that lists what the portal can see about you. Accept the invitation from a device you normally work on, if you can. The whole step takes under a minute.

Signing In

After the invitation is accepted, go to rdp.greenloopsolutions.com and sign in with the same work account. We recommend you bookmark the address once you are in.

Finding Your Connections

The page you land on is My connections. Each entry shows the name of the computer, its host address, the company it belongs to, and — if your access was granted for a limited period — the date that access expires. If a connection runs through a gateway, the entry says so.

Two buttons sit beside each entry:

• Download gives you the connection file immediately, using the settings your administrator chose.
• Options opens a details page where you can adjust a few display and sound settings before downloading.

If the list is empty, the page says that no connections are currently assigned to your account. That message is accurate and it is not a fault — it means the grant has not been made yet, or it has expired.

Adjusting Options Before You Download

The Options page shows what the connection is configured to do, and lets you change the handful of settings that are safe to leave in your hands. Which ones appear depends on the connection.

• Display size selects full screen or a fixed window size.
• Use all my monitors spans the session across every screen attached to your computer.
• Sound chooses whether audio plays on your computer, on the remote computer, or not at all.

The same page lists the redirection settings under a Redirection heading — clipboard, printers, drives, and smart cards — marked enabled or disabled. These are set by your administrator and you cannot change them here. That is deliberate: redirection is the part of a connection file that attackers abuse, so it stays under administrative control rather than yours. Some connections have no adjustable options at all, and the page will say so.

Follow the instructions to bypass the browser warnings and open the file:

How to tell if this worked

Once you’ve downloaded the file, move it to the location (like your desktop) that you prefer, and attempt to connect as you normally do. You should not get an “unknown publisher” dialog, and you should get connected to the destination computer exactly as normal. If you do get a warning, or the connection doesn’t work, please contact our service desk.

Frequently Asked Questions

I already have an .rdp file on my desktop that works. Do I need the portal?

Yes, and the one on your desktop should be deleted once you’ve confirmed the new one works. An older file is unsigned, which means Windows cannot tell you where it came from, and it carries whatever settings were current on the day it was made. Download a fresh one and delete the old.

Is this a new password to remember?

No. The portal uses the Microsoft 365 work account you already have, including whatever multi-factor method you already use with it. The guest invitation links the two; it does not create anything new.

I never got an invitation email. Should I be concerned?

In some cases, you may already have guest access. If you expect to have access to this, try signing in to rdp.greenloopsolutions.com. If you get an error message, please reach out to GreenLoop’s service desk.

The computer I need access to doesn’t show up in the portal.

Contact the GreenLoop service desk. Let us know what you’re seeing (or not seeing) there and we’ll handle the rest.

Can I email a connection file to a colleague who needs the same access?

In general, users should use their own login and not share files. In most cases, RDP files are unique and will not grant you access

Does the file keep working forever once I have downloaded it?

If the computer you’re accessing changes, you will need a new.rdp file. Otherwise, GreenLoop will let you know in the future if your file or access is slated to expire.

We would like remote access set up for more of our team. What is the next step?

Have your security authorizer contact the GreenLoop Service Desk and tell us who needs access and to which machines. We will handle the invitations and the grants, and each person will receive their invitation directly.
