The services that are running on this network would be file and printer sharing for the desktops. The File and print servers. I do not doubt that the two servers on this network are servers however they are not operating as servers. This most likely a workgroup where all resources are shared with every other resource. The service that is utilized for these workstations to communicate is called Netbeui Pronounced net-booey, NetBEUI is short for NetBios Extended User Interface. It is an enhanced version of the NetBIOS protocol used by network operating systems such as LAN Manager, LAN Server, and Windows for Workgroups, Windows 95 and Windows NT. It is utilized in workgroup networks to accomplish peer to peer communication, and it is not routable. So moving forward this protocol must be removed from all workstations as it will have no purpose after the network is upgraded.
The next service that can be removed from the network that will no longer be needed would be File and Printer Sharing for this Workgroup, because once this network is upgraded there will no longer be a need to share files amongst all of the workstations.
The application server will usually be dependent on the database server. If a web server is going to be added to connect to the outside world a firewall must be installed in order to create a barrier that will prevent external intrusion.
The router proposed in the network expansion must have some sort of network barrier to not only the Web server, the database and application server but also the 30 workstations as well. If 10 additional laptops
are going to be added to the network a decision needs to be made as to what form of connectivity these laptops will use will the use remote access services as well. All of these servers will need a patch management solution in order to prevent Operating System vulnerabilities.
Since the amount of switches is not given it can only be assumed that there are more than three concurrent connections at...
