Several users are reporting that after updating their Norton 360, they are no longer able to connect to the VPN, citing the Host Checker as the reason. Norton 360 (v2.x) is in the supported list of AntiVirus vendors. The specific Norton 360 version information is in the attached picture.
ESAP 1.3.8 does list Norton 2.X as being supported at the time ESAP was released. Norton 360 version 220.127.116.11 was released on March 6th 2008 I believe, considering that ESAP 1.3.8 was released June 6th 2008 I am surprised that you are encountering a problem such as this. I have had a search for any related issues reported by other customers in the past months and have not found any. I am assuming from your report that ALL of your clients that have upgraded to Norton 360 18.104.22.168 are now having this issue and that it is not the case that SOME 22.214.171.124 users are passed correctly? If my assumption is correct and you are statified with your host checker configuration; I would strongly suggest you raise a case with JTAC and they investigate your issue in greater detail.
