I have never encountered this problem ever before,except this morning. I intend to finish a lab, and startup the cisco router when some error information appearing. During  bootup of Cisco hardware through Cisco IOS software,error messages similar to these are displayed every time, what's more, it also appeared occasionally when you checked the interfaces' status, once you operate the router with commands, error messages similar to these are displayed:
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)

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.

Solution

To disable this feature, execute 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
           Router#reload
Hereafter,these error messages no longer appear at the next bootup of the router.
