Moving the DHCP Database Files
You may find that you need to dismantle or change the role of your DHCP server and
offload the DHCP functions to another computer. Rather than spend the time re-creating
the DHCP database on the new machine by hand, you can copy the database files and use
them directly. This is especially helpful if you have a complicated DHCP database with lots
of reservations and option assignments.
By copying the files, you also minimize the amount of human error that could be
introduced by reentering the information by hand.
Compacting the DHCP Database Files
There may be a time when you need to compact the DHCP database. Microsoft has a
utility called jetpack.exe that allows you to compact the JET database. Microsoft JET
databases are used for WINS and DHCP databases. If you wanted to use the jetpack
command, the proper syntax is
JETPACK.EXE <database name><temp database name>
After you compact the database, you rename the temp database to dhcp.mdb .
Summary
DNS was designed to be a robust, scalable, and high-performance system for resolving
friendly names to TCP/IP host addresses. This chapter presented an overview of the basics
of DNS and how DNS names are generated. We then looked at the many new features
available in the Microsoft Windows Server 2012 R2 version of DNS, and we focused on
how to install, configure, and manage the necessary services. Microsoft's DNS is based on
a widely accepted set of industry standards. Because of this, Microsoft's DNS can work
with both Windows- and non-Windows-based networks.
This chapter also covered the DHCP lease process as it relates to TCP/IP configuration
information for clients. The following stages were covered: IP discovery, IP lease offer, IP
lease selection, and IP lease acknowledgment. You learned how to install and configure
the DHCP server on Windows Server 2012 R2 and how to create and manage DHCP
scopes and scope options. I also discussed the authorization of DHCP servers within Active
Directory and scopes for IPv4 and IPv6 and showed how to create them. Finally, I covered
superscopes as well as managing client leases with the options therein.
