  No route to host.
  A socket operation was attempted to an unreachable host. See WSAENETUNREACH.</p>

  10051
  Network is unreachable.
  A socket operation was attempted to an unreachable network. This usually means the local software knows no route to reach the remote host.</p>
  
  <p>Is this a network error on customer network? 
  Is it something we can advise customer to do?</p>
  
  <p>WCF Client was able to connect to the server service before and seems that problem disappeared after reboot of machine (or maybe network problem was fixed in the meantime).</p>
  
  <p>Thank you</p>
