External Network User Information Management Server Client PC WebDAV Server Figure 1 An example of MFP s use environments An intra office LAN exists as a network in the office e MFP is connected to the client PCs via the intra office LAN and has mutual data communications When a SMTP FTP or WebDAV server is connected to the intra office LAN MFP can carry out data communications with these servers too The DNS service will be necessary when setting a domain name of the SMTP FTP WebDAV server It is also assumed to unify management of user IDs passwords in a server In this case TOE can control access to the MFP by using the user registration information in the user information management server When the intra office LAN connects to an external network measures such as connecting via a firewall are taken and an appropriate setup to block access requests to the MFP from the external network is applied e The intra office LAN provides a network environment that cannot be intercepted by office operations including using switching hubs and installing wiretapping detectors The public line connected with MFP is used for communications by Fax and the remote diagnostic function Copyright c 2009 KONICA MINOLTA BUSINESS TECHNOLOGIES INC All Rights Reserved 8 111 bizhub C652 bizhubC
