Jerem Posted June 8 Share Posted June 8 Hello, I’ve been a successful Unraid user for years, and this is the first time I’ve encountered an issue that requires assistance. I’m currently running the latest version of Unraid, hosting multiple Docker containers and a Windows 11 VM. For years, I’ve been connecting to the Windows 11 VM via RDP on my LAN without any issues. I use this VM daily for about 8 hours to run Microsoft Office applications. However, I’ve recently started experiencing frequent RDP disconnections. The error message I receive is: “You have been disconnected because another connection was made to the remote computer. Error code: 0x3. Extended error code: 0x5.” I’ve checked the logs of my VM and didn’t find anything unusual. I also don’t suspect any issues with my PFsense DHCP server or my TP-Link switch. I would appreciate any suggestions or assistance in troubleshooting this issue. Thank you very much! Quote Link to comment
JonathanM Posted June 8 Share Posted June 8 Can the RDP port of this VM be reached from WAN? Sounds a little like someone or something is trying a brute force or denial of service attack. Another thought, see if it's linked to that specific user account, set up another account and use it for a bit and see if the same thing happens. Quote Link to comment
Jerem Posted June 8 Author Share Posted June 8 Thank you Jonathan. I will try your recommendations and reports back. I have just disabled the firewall rule on the PFsense that allows RDP on the WAN (It was only allowing traffic very specific IP addresses anyway that I specified). I will try to change the user too and report back. Quote Link to comment
Jerem Posted June 8 Author Share Posted June 8 Unfortunately, I’m still experiencing persistent disconnections, despite the fact that the RDP is not permitted from the WAN. I’m not considering logging in as a different user because there’s only one user account (the admin account) on this Virtual Machine (VM), and it’s associated with my Microsoft account. Any other suggestions? Quote Link to comment

Why does that preclude testing with another account temporarily? Just add a user, and log in with those credentials. Quote Link to comment
Jerem Posted June 8 Author Share Posted June 8 Hi Jonathan. Thank you for your message. I have created a new user account on this Win 11 VM and I am testing with RDP. I will revert back with the results soon. Quote Link to comment
Jerem Posted June 9 Author Share Posted June 9 Unfortunately, the same RDP disconnections symptoms with the new Windows local user account are still occuring. What shall we try next? Quote Link to comment
JonathanM Posted June 9 Share Posted June 9 Which antivirus software suite are you running on the local PC? Quote Link to comment
Jerem Posted June 9 Author Share Posted June 9 I am running the free version of Bitdefender on both my local Win 11 PC and win 11 VM. Quote Link to comment
Jerem Posted June 10 Author Share Posted June 10 I have uninstalled the antivirus on both my local Win 11 PC and win 11 VM, and still have exactly the same intermittent RDP error. Quote Link to comment
