This document provides explanations of service configuration errors encountered during initial hardware bootup when you run Cisco IOS® software.
There are no specific requirements for this document.
This document is not restricted to specific software and hardware versions.
The information in this document was created from the devices in a specific lab environment. All of the devices used in this document started with a cleared (default) configuration. If your network is live, make sure that you understand the potential impact of any command.

Occasionally, during bootup of Cisco hardware through Cisco IOS software, error messages similar to these are displayed:
%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://255.255.255.255/3620-confg (Socket error)
%Error opening tftp://255.255.255.255/3620.cfg (Socket error)
These error messages are related to the default service configuration option built into Cisco IOS software, which attempts to access the service configuration files from a network Trivial File Transfer Protocol (TFTP) server.
In order to disable this feature, issue the no service config global command.
Router#config terminal Enter configuration commands, one per line. Router(config)#no service config Router(config)#exit Router#copy running-config startup-config
These error messages no longer appear at the next bootup of the router.
