title: Unable to attach to remote geth: Invalid pipe address '/.rinkeby/geth.ipc'
body: <p>I'm on Windows trying to connect to Ethereum Testnet via rinkeby.</p>
  
  <p>I downloaded geth 1.8.2 and Ethereum Wallet 0.9.3</p>
  
  <p>I gave 1st command as:</p>
  
  <blockquote>
    <p>geth --rinkeby --fast --cache=1024</p>
  </blockquote>
  
  <p>NOTE: after above command, I get the url on cmd as:</p>
  
  <blockquote>
    <p>url=\\.\pipe\geth.ipc</p>
  </blockquote>
  
  <p>And 2nd command in another command prompt as:</p>
  
  <blockquote>
    <p>geth --datadir=./rinkeby attach</p>
  </blockquote>
  
  <p>The same commands were working earlier.</p>
  
  <p>I uninstalled both geth and Ethereum wallet and installed latest versions. I tried the commands on the earlier versions also where they were working but now they are not.</p>
  
  <p><strong>I also tried connecting to Private net just now, but got the error message on 2nd command prompt as:</strong></p>
  
  <blockquote>
    <p>Unable to attach to remote geth: no known transport for URL scheme "c"</p>
  </blockquote>
  
  <p>Thanks in advance!</p>
