I'd assume that 'telnet hostname 443' is intended to be a test for an
https web service - which should in fact not permit a connection without
ssl encryption. The linux version of telnet probably tries to do some
options negotiations before it says it is connected and perhaps the
windows version doesn't. A better test would be
wget https://adp.eease.com
