authentication rpc

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:

Cannot register service: RPC: Authentication error; why = Client credential too weak unable to register (X_PROG, X_VERS, udp)

Can anybody tell me what the cause of this error can be?

rpcinfo gives me this:

   program version netid     address                service    owner
    100000    4    tcp6      ::.0.111               portmapper superuser

    100000    2    udp       0.0.0.0.0.111          portmapper superuser
    100000    4    local     /run/rpcbind.sock      portmapper superuser
    100000    3    local     /run/rpcbind.sock      portmapper superuser

The weird thing is that I haven't even been using this pc the past week. Are there any services that should be running?

Hope you can help me out. Grtz Stefan

this error is linked to rpcbind,so you should stop service portmap like this:

sudo -i service portmap stop

then

sudo -i rpcbind -i -w

at end start service portmap:

sudo -i service portmap start
