I'm trying to get up and running on Server 2012 with one host server and 2 virtual machines. On all instances I'm having issues connecting to certain external servers. For example, if I go to crashplan.com or acronis.com, I get a "This page can't be
displayed" message. I can connect to other sites just fine (e.g., cnn.com). When I fire up telnet the behavior is the same... "telnet crashplan.com 80" gets a "could not open connection to host", while "telnet cnn.com 80"
returns the html.
I do not believe this is a DNS issue since nslookup resolves just fine. I've tried disabling the IE protection and the firewall to no avail.
I have dependencies on external services that are currently unreachable, so this is a major showstopper. The problem is the same on all 3 machines (1 host + 2 virtual). No other machines in my LAN have this problem.
Have you checked your IE settings? They have much tighter default security that earliers releaases of IE? Some web sites do some things behind the scenes that are not obvious, so a difference in settings could possibly change your results.
For telnet, have you checked your telnet settings? By default, telnet is not an allowed program through the built-in firewall.
