There is a lot of mumbo-jumbo out there about Juniper. It seems to me, that the main reason for using Juniper is to provide a VPN connection. The only thing the I have that remotely resembles a network(?) is that I use a router when I use my laptop.
Juniper Host Checker software provides an API (NHC_EndpointSecure) for third-party vendor integration. Third parties implement these APIs to securely exchange information with Host Checker.
This function is implemented by McAfee FireNHC.dll. When Host Checker calls method NHC_EndpointSecure, an access violation exception is created within the McAfee implementation of FireNHC.dll for this API.
