If you’re having trouble, try each of the solutions listed below until you find one that works for you.
Method 1: Disabling Network SharingÂ
Because Windows’s internet-sharing feature employs many port ranges that aren’t always reflected in Netstat, this one is a particularly odd offender.
Many customers, however, have said that the problem has been fixed for good after they turned off Internet Connection Sharing. Windows provides two options for turning off Internet Sharing. Use whatever approaches are easiest for you:

To disable Internet connection sharing go to the Network and Sharing Center in Control Panel.
- To access the Run dialogue, use the Windows key plus R. Next, hit Enter after typing “ncpa.cpl” to bring up the Network Connections panel.
- To access the connection’s settings, right-click it in the Network Connections box and select Properties.
- If you don’t want other people on your network to be able to use your computer’s Internet connection, you can disable that feature by going to the Sharing tab in your network’s Properties page and unchecking the box.
- First, try restarting your computer to see if it clears up the error.
Turning Off the Internet & Sharing Service
- Open the Run dialogue box by pressing the Windows key plus R. Next, press Enter after typing “services.msc” to bring up the Services window.
- Start by navigating to the Services panel, and then finding the Internet Connection Sharing (ICS) service in the right-hand pane. If you find it, double-click it to activate it.
- Second, set Startup type to Disabled on the General tab of the Internet Connection Sharing (ICS) screen.
- Give your machine a restart and see if the problem still persists.
Method 2: The alternative is to disable your third-party antivirus software or whitelist the connection.
Several customers have requested investigations into whether or not third-party security suites are disrupting SMTP traffic. Several antivirus programmes, including McAfee, BitDefender, and Avast, have been verified to have restricted localhost traffic on specific ports. This is the typical procedure for protecting against mass mailing attacks on certain ports.
Some users have complained that the “an attempt was made to access a socket in a fashion banned by its access permissions” problem was caused by an overly restrictive firewall or another security filtering technology.
The solution to this problem is to whitelist the connection in your antivirus settings. Don’t forget that the procedure for creating a whitelist rule will vary from one client security system to the next.
You might try temporarily disabling your third-party antivirus software if you can’t figure out which connection is being blocked.

Method 3: Disconnecting from the Virtual Private Network
Some customers who were affected have determined that a virtual private network (VPN) client was the root of the problem on their end. An implicated VPN client may be to blame for the “an attempt was made to access a socket in a way banned by its access permissions” problem that occurs in certain situations when a localhost connection is attempted.
You can verify this assumption applies to your situation by abandoning your VPN and checking for the disappearance of the problem.
Assuming the error notice no longer appears after the VPN is disconnected, you will need to either switch VPN clients or disable them altogether whenever the error-causing activity is being carried out.
