RDP Session not connecting AND Microsoft Defender 365

Mike Prentice 21 Reputation points

I recently purchased Visio Subscription via Plan 2. Apparently, in doing so I have now activated this Microsoft Defender service. As a result, I am unable to do work-based activities; namely launch RDP. This is a real problem and unsure who/where/how to get real support to fix this but it is something that needs to be addressed. I also am unable to lunch certain sites via Outlook. I requested a password to be reset, then send you the link via email and I open it up and poof MS Defender saying No. This is my belief that RDP no longer works as it worked before no issue, now it does not.

I get the generic invalid credentials message. I am looked up a number of sites to fix the problem and at this point, my network connection on my work laptop is SO BAD, I am using my mobile hotspot as the network configuration is so messed up.

I have turned it off, that did not fix any problem. I then turned off the Windows firewall, which made it worse as in I could not get to any webpage and my network connection to my home wifi no longer will connect.

    Might try from PowerShell from source and target (use target address in both cases).

    Test-NetConnection -ComputerName "" -CommonTCPPort "RDP" -InformationLevel "Detailed"

    It indirectly helped determine what the real cause was. It seems the Admin person did create a domain but did not tell me the domain name. So I assumed no domain while logging in. Thus it really was a login error, not anything else. The confusion was also complicated as I created a new profile on my Windows laptop AND installed a Visio Plan 2 software where suddenly I could not launch certain sites. This pushed the direction towards an internal networking configuration error, which can happen with RDP. In the end, it was the fact I did not know the domain name of the server I was logging into.

    I accepted the answer but technically it was not the answer. It helped find the answer. Hopefully the additional comments will help anyone else with this issue.
