Cannot Bind Socket
Posted by Linda, Last modified by on 09 February 2007 12:26 AM
Instructions for finding what process is holding a socket, for instance, port 80 with Web Host.

Open the Task Manager, Select the View menu / Select Columns. Add the PID (Process Identifier).

Start a DOS box. Start / Run. Type cmd, Enter. At the prompt type:

netstat -a -n -o

This will display all ports, state and a PID, that is an identifier for the process that is using the ports.

The services that primarily use the ports 80 & 443 are as follows,

80 TCP HTTP Windows Media Services
80 TCP HTTP World Wide Web Publishing Service
80 TCP HTTP SharePoint Portal Server

443 TCP HTTPS HTTP SSL
443 TCP HTTPS World Wide Web Publishing Service
443 TCP HTTPS SharePoint Portal Server
443 TCP RPC over HTTPS Exchange Server 2003
