title: Connecting two EC2 Windows instances
body: <p>I need to connect two Windows EC2 instances. One instance will serve as an Octopus Deploy Server, the other as a Deployment target with a tentacle.
  The two instances are running in the default VPC with the same security group.
  For now I allowed all TCP traffic through the security group.
  Octopus Server needs port 10933 opened to communicate with it's tentacles. I created a firewall rule to allow outgoing traffic through port 10933 on the Octopus Server instance and an Incoming Firewall rule to allow traffic through port 10933 on the Tentacle instance.</p>
  
  <p>The two instances can ping each other, but the Octopus Server is unable to find the tentacle on the other EC2 instance.</p>
  
  <p>What am I missing?</p>
