Method 1: Disabling Internet Connection Sharing

There are two different ways that will allow you to disable Internet Connection Sharing on Windows. Follow whichever methods are more convenable for you:
Disabling Internet Connection Sharing via Control Panel
Disabling the Internet Connection Sharing Service
Method 2: Uninstalling your 3rd party AV or whitelisting the connection
A lot of users have pointed out that 3rd party security suits should be checked to confirm that they’re not interfering with the SMTP connections. McAfee, BitDefender, and Avast are confirmed to blocked certain ports used by localhost connections. With certain ports, this is standard behavior in order to prevent mas mail attacks. As some users have reported, an overprotective firewall or a similar security filtering tool can be responsible for causing the “an attempt was made to access a socket in a way forbidden by its access permissions” error. You can typically resolve this issue by whitelisting the connection that is being blocked from your AV settings. Keep in mind that the steps of establishing a whitelist rule will be different depending on your security solution client. If you’re having trouble identifying the connection that is being blocked, you can temporarily uninstall your 3rd party antivirus and see if the issue is resolved. Note: Keep in mind that disabling the real-time protection of your AV will not help you reach a conclusion since the same rules will remain firmly in place. If you decide to uninstall your 3rd party AV, you can follow this step by step guide (here). In the event that this method wasn’t applicable or you’ve determined that the 3rd party client was not responsible for the error, move down to the next method below. Update: IP blocking clients such as PeerBlock might automatically block an IP that is involved in the operation that is failing. Several users have reported that the issue was automatically resolved after creating a rule exception or uninstalling the IP blocking software.

Method 4: Restarting the Internet Information Services (IIS)
Several users have reported that the issue was resolved after they restarted the Internet Information Services (IIS) from an elevated Command Prompt window. But keep in mind that restarting the IIS servers will drop all internet services including FTP, SMTP and NNTP and any data held in the applications handling the connections is lost.

To test whether this theory holds true in your case, simply disconnect from the VPN network and see if the issue is resolved. If the error message is no longer occurring while VPN is disconnected, you need to look for a different VPN client or at least keep it disabled while performing a certain task that will trigger the error.
