title: Failed to run mongod, windows 10, "T�r: errno:11001 No such host is known."
body: <p>I am very new, I have looked and looked but haven't found anything that helps. I hope this isn't a super obscure problem.</p>
  
  <p>I am running windows 10 and have installed MongoDB. I am attempting to get mongod to run but right after it starts listening on port 27017 it kicks back:</p>
  
  <blockquote>
    <p>[HostnameCanonicalizationWorker] Failed to obtain address information for hostname T�r: errno:11001 No such host is known.</p>
  </blockquote>
  
  <p>And that is where it stops. I have tried many things. I run the console in administrator, I reinstalled MongoDB, I have made sure the port is not being blocked by the firewall. I even gave trying other ports a go.
  Everything that I have looked up says that where I am at mongod should now run and be listening on port 27017.</p>
  
  <p>Here it is in full:</p>
