netstat -aon | findstr 443 Last column is process number which ties back to a process in the task manager (probably need to add the coulumn via "Veiw->Select Columns"

IIS in its v5 form, takes the cake (socket pooling sucks) Just love the word sucks, don't you?
http://support.microsoft.com/kb/259349/EN-US/
To work around this behavior, disable socket pooling in IIS as follows:
1. At a command prompt, switch to the "C:\InetPub\AdminScripts" folder.
2. Type the following command:
CSCRIPT ADSUTIL.VBS SET W3SVC/DisableSocketPooling TRUE
