title: RPC Authentication error
body: <p>Last week I was using RPC and could run my RPC server program just fine. However, today I tried to start it again and I am getting this error:</p>
  
  <blockquote>
    <p>Cannot register service: RPC: Authentication error; why = Client
    credential too weak unable to register (X_PROG, X_VERS, udp)</p>
  </blockquote>
  
  <p>Can anybody tell me what the cause of this error can be?</p>
  
  <p>rpcinfo gives me this:</p>
  
  <pre><code>   program version netid     address                service    owner
      100000    4    tcp6      ::.0.111               portmapper superuser
      100000    3    tcp6      ::.0.111               portmapper superuser

  <p>The weird thing is that I haven't even been using this pc the past week.
  Are there any services that should be running?</p>
  
  <p>Hope you can help me out.
