Some customers reported obtaining the “an attempt was made to access a socket in a way banned by its access permissions” error when trying to use the ipconfig/renew command in CMD in order to fix their network connection.
Other users say that same issue is occuring when they try to establish an Apache server. However, practically all afflicted users say that the issue started happening after a Windows automatic update has been deployed.
Method 1: Eliminating File Sharing Over the Internet
Since Windows’s internet-sharing feature employs multiple port ranges, not all of them will show up in Netstat or a similar programme, this one is a bit of an oddball offender.
Nonetheless, a number of customers have claimed that turning off Internet Connection Sharing permanently fixed the problem for them.
If you want to stop Windows from sharing your Internet connection with other programmes, you can do so in two ways. To the extent that different approaches work better for different people, go with those.
Turning off Network Sharing in Windows Control Panel
Step 1: You may bring up the Run dialogue box by pressing the Windows key plus R. To access the Network Connections window, type “ncpa.cpl” and hit Enter.
Step 2: Right-click the connection you want to modify and select Properties in the Network Connections window.
Step 3: Turn off the option to share your Internet connection with other computers on your network by going to the Sharing tab in your network’s properties screen and deselecting the box.
Step 4: Attempt a system restart to see if the error message disappears.
Inactivating the P2P Sharing Service on the Internet
Step 1: Simply use the Windows key plus R to bring up the Run window. The Services window will then load once you type services.msc and hit Enter.
Step 2: You may find the Internet Connection Sharing (ICS) service inside the Services panel, on the right side of the screen. You should double-click it after you find it to turn it on.
Step 3: To disable Internet Connection Sharing, select the General tab in the ICS settings menu.
Step 4: Try to solve the problem by restarting your computer.
Method 2: By Disabling Or Whitelisting The Antivirus Programme, You Can Avoid Potential Threats.
Several customers have requested investigations into whether or not third-party security suites are interfering with SMTP connections. Several antivirus programmes, including McAfee, BitDefender, and Avast, have been verified to have restricted ports commonly used for localhost connections.
This is the expected behaviour for specific ports in order to protect against mass mailing assaults. For some users, the “an attempt was attempted to access a socket in a way banned by its access permissions” warning message appears when a firewall or other security filtering tool is set to a particularly strict level of protection.
Whitelisting the offending connection in your antivirus settings should fix the problem. Be aware that the procedure for creating a whitelist rule will vary based on the security solution client you’re using.
Remove your third-party antivirus software to check whether the problem goes away if you can’t figure out which connection is being blocked.
Method 3: Creating A Windows Firewall Exception
It turns out the “an attempt was made to access a socket in a way banned by its access permissions” problem can also be caused by the built-in Windows Firewall.
There have been reports from several users who experienced resolution after permitting the offending programme to interact over Windows Firewall. Users of SQL server have reported the most success with this approach, but you can easily modify the instructions to fix the mistake in another programme.
Check out our handy checklist to see what steps you need to take next:
Step 1: You may bring up the Run dialogue box by pressing the Windows key plus R. Then, hit Enter after typing “firewall.cpl” to launch Windows Defender Firewall.
Step 2: Select Allow an app or feature through Windows Defender Firewall from the menu within Windows Defender Firewall.
Step 3: Select the Settings cogwheel in the Allowed apps section.
Step 4: Find the offending app by searching the list of authorised software and features. After doing so, ensure sure the Private and Public toggles for the relevant app are turned on.
Step 5: After making the aforementioned alterations, reboot the machine to check if the “an attempt was made to access a socket in a fashion banned by its access restrictions” message disappears.
