Security Trust Issue?

[Michael E. Matthews]

I have just installed a new 4.2 box into a 4.1 existing infrastructure. I am receiving a "Failed Server Name Validation" error in the HTTP server on the host when I run a software status polling query from the CMS. I can install software on the host from the repos and can login to the CMS, repository and the host VCA....It all worked fine in 4.1. Where does 4.2 choose the name to validate and further, what is the validation process? Thank you in advance.
