An information processing method and apparatus for enabling more prompt sign-up. A network management server at step S62 received am equipment serial number from an information processing apparatus and, at step s63, references a database to retrieve a received equipment serial number. If the equipment serial number has not been found, the program moves to step S16 where a command for initiating manual setting is sent to an information processing apparatus. If the equipment serial number has been found, the program moves to step S81 to verify whether or not the admittance made or admittance not as yet made, recorded in the database in association with the equipment serial number received is admittance made. If the verified result indicates admittance not as yet made, the program moves to step S82 where the network management server sends an automatic setting initiating command to the information processing apparatus.
