Windows 10/11 Pro - Constant need to reset Winsock / TCP stack to avoid RDP connection error

Anonymous
2022-06-21T09:50:54+00:00

Dell Latitude 3520 – 1 device affected

RDP fails to find the host computer until the TCP stack is reset, while browser traffic is unaffected

RDP Connection error - Remote Desktop can’t connect to the remote computer

Wi-Fi or Ethernet are connected with data transfer, and I can successfully ping the RDP server at all times

In elevated CMD run:

  • ipconfig /flushdns
  • ipconfig /release
  • ipconfig /renew
  • NETSH winsock reset
  • NETSH int ip reset

After a reboot the above commands resolve the issue for 1 attempt, the RDP connects, but after being disconnected the issue reoccurs until the TCP stack is reset again.

Tried running the following independently with reboots which didn’t resolve the issue until both were ran together:

  • NETSH winsock reset
  • NETSH int ip reset

Registry entries seem the same when the issue is occurring and not:

  • SYSTEM\CurrentControlSet\Services\Tcpip\Parameters
  • SYSTEM\CurrentControlSet\Services\DHCP\Parameters

IP Addresses assigned to the network adapter in use, and the VPN adapter are the same when the issue occurs and while it’s working.

Reinstall of network adapters hasn’t helped, latest drivers installed

Upgrade from Win10 to Win11 hasn’t helped, latest updates installed – MS & Dell

Reset of device, wiping apps and data hasn’t helped

Issue affects domain-joined user and a local account set up for testing – all accounts

Following the suggestion here with the below commands helped, now the RDP will connect/disconnect/reconnect 3-5 times before producing the Remote Desktop can't connect error, and when the error does reappear it’s resolved by a reboot:

  • ipconfig /flushdns
  • ipconfig /registerdns
  • ipconfig /release
  • ipconfig /renew
  • NETSH winsock reset catalog
  • NETSH int ipv4 reset reset.log
  • NETSH int ipv6 reset reset.log

How do I make this problem disappear altogether though?

    I also went through the same troubleshooting steps (repeatedly), removing from the domain, removing the anti-virus and firewall. I

    was using an older Dell (also running Windows 10 21H2) to test with the same WIFI/VPN/RDP connections with no issues...the issues

    only appeared on the 2 Dell Latitude 3520's. The issue might clear itself temporarily (usually after the domain removal or changes to the Virus/Firewall
    software) but would return after a few attempts.

    Again, running this network reset script cleared the issue on both systems immediately.

    I have the same problem on 2 Dell 3520's. We are connecting RDP via VPN through WIFI. I can pass ping, traceroute, etc through the
    VPN connection, but an RDP or Telnet fails with no outgoing connection attempts appearing. An older Dell using the same

    WIFI and VPN has no problem. We also have no connection problems when connecting locally through our intranet WIFI.

    We are running Windows 10 21H2 with all of the patches. Both Dell's have been completely

    updated with Dell updates.

    After running this reset script and restarting, both systems connected RDP on the first attempt.

    Hi,

    Thanks for your post in Microsoft Community.

    I understand that you're running into an issue where Remote Desktop requires a constant reset of the Winsock/TCP stack to connect properly.

    This question is beyond our support scope, I think you may need to ask this question in a more specialized forum, Microsoft Docs (directed to RDP section) has more people familiar with RDP, I believe you can get questions here Answer.

    Thank you for your understanding, and I hope you can get an answer as soon as possible.
