Required Server Roles: None.

Minimum OS Version: Windows Server 2008, Windows Vista.

Event Versions: 0.

Field Descriptions:

Application Information:

  • Process ID [Type = Pointer]: hexadecimal Process ID of the process that was permitted to bind to the local port. Process ID (PID) is a number used by the operating system to uniquely identify an active process. To see the PID for a specific process you can, for example, use Task Manager (Details tab, PID column):

    If you convert the hexadecimal value to decimal, you can compare it to the values in Task Manager.

    You can also correlate this process ID with a process ID in other events, for example, “4688: A new process has been created” Process Information\New Process ID.

  • Application Name [Type = UnicodeString]: full path and the name of the executable for the process.

    Logical disk is displayed in format \device\harddiskvolume#. You can get all local volume numbers by using diskpart utility. The command to get volume numbers using diskpart is “list volume”:

Network Information:

  • Source Address [Type = UnicodeString]: the local IP address of the computer running the application.

    • IPv4 Address

    • IPv6 Address

    • :: - all IP addresses in IPv6 format

    • 0.0.0.0 - all IP addresses in IPv4 format

    • 127.0.0.1, ::1 - localhost

  • Source Port [Type = UnicodeString]: the port number used by the application.

  • Protocol [Type = UInt32]: the protocol number being used.

Service Protocol Number
Internet Control Message Protocol (ICMP) 1
Transmission Control Protocol (TCP) 6
User Datagram Protocol (UDP) 17
General Routing Encapsulation (PPTP data over GRE) 47
Authentication Header (AH) IPSec 51
Encapsulation Security Payload (ESP) IPSec 50
Exterior Gateway Protocol (EGP) 8
Gateway-Gateway Protocol (GGP) 3
Host Monitoring Protocol (HMP) 20
Internet Group Management Protocol (IGMP) 88
MIT Remote Virtual Disk (RVD) 66
OSPF Open Shortest Path First 89
PARC Universal Packet Protocol (PUP) 12
Reliable Datagram Protocol (RDP) 27
Reservation Protocol (RSVP) QoS 46

Filter Information:

  • Filter Run-Time ID [Type = UInt64]: unique filter ID that blocks the application from binding to the port. By default, Windows firewall won't prevent a port from binding by an application, and if this application doesn’t match any filters, you'll get value 0 in this field.

    To find a specific Windows Filtering Platform filter by ID, run the following command: netsh wfp show filters. As a result of this command, the filters.xml file will be generated. Open this file and find the specific substring with the required filter ID (<filterId>), for example:

  • Layer Name [Type = UnicodeString]: Application Layer Enforcement layer name.

  • Layer Run-Time ID [Type = UInt64]: Windows Filtering Platform layer identifier. To find a specific Windows Filtering Platform layer ID, run the following command: netsh wfp show state. As a result of this command, the wfpstate.xml file will be generated. Open this file and find the specific substring with the required layer ID (<layerId>), for example:
