Enzoic for Active Directory uses a local port for communications between its processes on each Domain Controller where it is running. This is communications between the password filter driver and the Enzoic service that run locally on the machine.

The default port is 6164. If this port is being used by other software on the system, unexpected behaviors may result. If necessary, the port can be changed using the following registry setting after install:

Registry Key: "HKEY_LOCAL_MACHINE\SOFTWARE\WOW6432Node\Enzoic\Enzoic for Active Directory"

Value Name: ServicePort 

Value Type: DWORD

Value: (new port to use)
