ENTERPRISE SERVER MANAGEMENT2
Introduction
An organization has suffered serious outage within IT system as for failure of
hardware. The business of the organization over last few years have undergone huge shift
from the sales to new system of e-commerce which brought it from a single number
percentage with respect to sales to representation of third of half of their sales. However,
increase in usage and the e-commerce system’s popularity did not have same interest and
investment in IT teams who manage, run and develop the e-commerce systems that is forced
in continuing with less staff members and quite less budgets. After detecting the cause of the
outage, it is determined by the IT team that the outage caused due to failure of single device,
however one that is really a crucial equipment of the system. It took several services down,
which included prevention of online sales, costing their business even after one whole
weekend of their sale. Senior management realized that IT is needed and asked IT department
for creating proposal for overhaul and modernization of existing services of IT for building
better scalability and resilience for services that are needed for their business.
The major aim for the changes in IT area is in attempting for minimizing risks of
repeat event’s risks. Team of senior management is eager for reacting quickly in correcting
the faults within their system, hence speed of implementation must be considered as of high
priority where significant downsides are not brought by it in ongoing maintenance and
operations. There are two sites for the business, main HQ having 350 users having leased
connection of line and the secondary site having 100 users on basic service of ADSL. Every
service, which includes those that are accessible externally are hosted in secondary site and
main HQ, accesses internal only by services through VPN. Secondary sites has issues
constantly in accessing both internet and internal services of IT that the modernization must
address also.

Key Infrastructure Services
Dynamic Host Configuration Protocol (DHCP)
It is protocol of network management that is used on networks of UDP/IP where
server of DHCP assigns the IP address dynamically and all other parameters of network
configuration for every device within network, so these could communicate with IP’s all
other networks. DHCP server enables the systems in requesting networking parameters and
IP addresses from Internet Service Provider (ISP) automatically, by reducing need of user or
network administrator for assigning IP addresses manually into every network device (Bilge
et al. 2014). Without a server of DHCP, a system or device within the network should be
assigned manually IP address or by assigning itself with APIPA address that would be
enabling it in communicating outside of the local subnet.
DHCP could be implemented within networks having different range of size. A
residential gateway or router could be enabled for acting as server of DHCP. Maximum
network routers get different IP address in ISP network. In local network, server of DHCP
assigns the local IP address for every device that is connected with the network (Issac 2014).
DHCP could be implemented within the system of the organization for providing bettor
networking system. Cost of implementation of DHCP is around 600 dollars.
DHCP needs routine maintenance and would unlikely have various problems. One of
these problems would likely be a sign that everything is not right with DHCP. A warning
message is received “Client of DHCP cannot renew IP address lease” (Tripathi and Hubballi
2015). User would find that the web cannot be accessed or the program would work. When
attempt is made in using DHCP manager, warning message would be received. When there is
attempt of starting service of DHCP, warning message would be received that service is
unable to start. In each of the cases, the start of DHCP service should be verified (Dinu and
