Problem: Service Configuration Error Messages

sometimes displays similar Error Messages during Cisco IOS software startup of a Cisco device:
% 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)
A practical example:
% SYS – 4 – CONFIG_RESOLVE_FAILURE: System config parse the from (TFTP:// 255.255.255.255 cisconet. CFG) failed
These error messages are related to the default service configuration options built into Cisco IOS software, which attempts to access the service configuration file from the (TFTP) server.

Enter configuration commands, one per line.  

Router(config)#no service config

Router(config)#exit

Router#copy running-config startup-config

Which error messages will not appear after the router’s next restart.
