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
