Server 2012 - Connectivity issues - "This page can't be displayed"

-

i'm trying , running on server 2012 1 host server , 2 virtual machines. on instances i'm having issues connecting external servers. example, if go crashplan.com or acronis.com, "this page can't displayed" message. can connect other sites fine (e.g., cnn.com). when fire telnet behavior same... "telnet crashplan.com 80" gets "could not open connection host", while "telnet cnn.com 80" returns html.

i not believe dns issue since nslookup resolves fine. i've tried disabling ie protection , firewall no avail. 

i have dependencies on external services unreachable, major showstopper. problem same on 3 machines (1 host + 2 virtual). no other machines in lan have problem.

thoughts?

thanks in advance

have checked ie settings?  have tighter default security earliers releaases of ie?  web sites things behind scenes not obvious, difference in settings possibly change results.

for telnet, have checked telnet settings?  default, telnet not allowed program through built-in firewall.
