Determine which process is using a specific port using PowerShell.

If you find that a process is using a TCP port and you want to know which process is using that port it's easy with PowerShell using the Get-NetTCPConnection and Get-Process cmdlets.


# Determine which process is using port 443

$owningProcess = (Get-NetTCPConnection -State Listen -LocalPort 443|SELECT OwningProcess)[0];
$processName = Get-Process -Id $owningProcess.OwningProcess|SELECT ProcessName;
Write-Host "Port 443: $($processName.ProcessName)";

Network Audit and Documentation     Sometimes we forget about some of Microsoft's very annoying "helpful" additions. This is one I just got stuck on when trying to access a UNC share you are constantly prompted for a username and password. When you try to map a network drive you receive the following error System error 86 has occurred. The specified network password is not correct. After a while of trying to remember what this meant, I realise this is the following option in Folder Options.
