How to find out the application name using PID (process identifier)

I am trying to install a VisualSVN server and have the message "The specified TCP port is busy with another service." How can I find which service or application is using port 443? "netstat -aon" only shows me

UDP 0.0.0.0:443 *:* 4252

OS is Windows. And yes, I used to have VisualSvn Server on this computer. Then I uninstalled it (I do not see any SVN service) and would like to reinstall.

I would also like to know which authentication mode I should choose. Given that I want to have a repository on an external drive.

Thanks in advance, Alex.

netstat output

  • In recent versions of Windows, run the Get-NetTCPConnection PowerShell cmdlet with PowerShell 5.

    For example, run this command to get the name of the process that is listening on port 443 on your computer:

     PS C:\> Get-Process -Id (Get-NetTCPConnection -LocalPort 443).OwningProcess Handles NPM(K) PM(K) WS(K) CPU(s) Id SI ProcessName ------- ------ ----- ----- ------ -- -- ----------- 143 15 3448 11024 4572 0 VisualSVNServer
