"%Error opening tftp://255.255.255.255/network config" Error Message

You may get the following error messages while your Cisco device is booting up:

%Error opening tftp://255.255.255.255/network-confg (Socket error)
%Error opening tftp://255.255.255.255/cisconet.cfg (Socket error)
%Error opening tftp://255.255.255.255/router-confg (Socket error)

This is due to a default service configuration option included in the IOS which is trying to access a TFTP server in order to download its configuration file.


In order to fix this issue, issue the following command in global configuration mode:
Router (config)#no service config
