While installing Norton 360, connected to the computer over Remote Desktop (within my home network), I lost the connection when install had finished (install screen showing "connecting to norton").
From then on, I'm no longer able to RDP to that computer.
Solution: remove Norton 360 Crap and never use it again, as it doesn't respect current firewall rules, and RDP/3389 seems to be unknown by Norton as a user-selected option in the windows (11 Pro) settings. I tried disabling and re-enabling remote desktop in windows settings, but the result remains (norton blocks even local access).
I have had no issues with RDP working on my systems. And I never had to touch any firewall rules.
You seem to have already decided against Norton, but another question. Did you run LiveUpdate manually a few times, restarting as necessary, until no updates are available? Then restart again. Restarting, not shutdown and startup again if you have Windows Fast Startup feature enabled. If you use Windows 8/8.1 or 10 or 11, there can be an issue with the Windows Fast Startup feature.. See more information here. That might have reset your network connections.
Wrote a reply, but it disappeared (probably norton virus scanner that scans the reply, as with the mentioned removed "malware", which I now cannot find anything about what was deleted, just hope it wasn't something important so I have to reinstall that computer)
I tried both with and without restarting the computer which I installed Norton on (install went fine, it just lost the connection when 360 started after the installation). I tried to reconnect multiple times, also after manually adding an exception rule under "traffic rules". I won't reinstall 360 on any computer anymore. I have 20+ one year "free" licenses (for 3 or 5 devices each) to share if anyone else want to be Nortons guinea pig.
I rather pay for Kaspersky (49 eur, 5 devices for the two first years) than using a free lifetime license of this crap.
Not sure if this applies here. Years ago, I was beta testing Norton security products and I tried to use RDP to install from my daily use computer to my test rig. I ran into issues and could not complete the installation. Working with the Norton engineers on this and it was determined that you could not use RDP to install onto a remote computer. I don't know if things have changed since then.
Did you try restarting both computers after you tried the 360 installation?
Norton Firewall blocks the following Windows services by default on a public network. You can choose to always allow any of these services on a public network by checking the Allow box next to the service name.
I also tried adding the rdp rule manually, but it didn't work.
While uninstalling the Crap, it did a (probably) false positive detection of a "trojan". I had no chance of investigating what file in c:\windows it deleted without letting me making an active choice.
This was on a newly installed windows 11 pro computer, without any "uncommon" installations or "patches" for installed applications.
