Check which program occupies the port

During the php environment today, after the software is installed, the service cannot be started. Previously, tomcat and apache were uninstalled, and IIS was not installed, but 80PortOccupied.
The solution is as follows:
Use doscommandViewPortProcess number, and then compare the task process number to find out.
C: \ Documents ents and Settings \ Administrator> netstat-ano
Active Connections
Proto Local Address Foreign Address State PID
TCP 0.0.0.0: 80 0.0.0.0: 0 LISTENING 3676
TCP 0.0.0.0: 135 0.0.0.0: 0 LISTENING 1592
TCP 0.0.0.0: 445 0.0.0.0: 0 LISTENING 4
C: \ Documents ents and Settings \ Administrator> tasklist

Image name PID session name session # memory usage
========================================================== ======================================
Iexplore.exe 5300 Console 0 43,252 K
Thunder5.exe 3676 Console 0 14,220 K
Conime.exe 5840 Console 0 4,616 K

The result is clear. The reason for thunder is that it is OK after it is closed. The evil thunder actually occupies less than 1024Port.
