DHCP for Windows 2000
by Neall AlcottDHCP for Windows 2000 is custom-designed for system administrators who are responsible for configuring and maintaining networks with Windows 2000 servers. It explains the DHCP protocol and how to install and manage DHCP on both servers and clients--including client platforms other than Windows 2000.
DHCP for Windows 2000
by Neall AlcottDynamic Host Configuration Protocol (DHCP) is an open standard Internet protocol used to allocate and manage IP addresses dynamically. Before DHCP came along, administrators had to manually configure each host on a network with an IP address, subnet mask, and default gateway. Maintaining the changes and the associated logs took a tremendous amount of time and was prone to error. DHCP uses a client/server model in which the system updates and maintains the network information dynamically. Windows 2000 provides enhanced DHCP client-server support. DHCP for Windows 2000 is custom-designed for system administrators who are responsible for configuring and maintaining networks with Windows 2000 servers. It explains the DHCP protocol and how to install and manage DHCP on both servers and clients--including client platforms other than Windows 2000. Readers get detailed and explicit instructions for using Windows 2000 DHCP to manage their network IP configurations much more efficiently and effectively.They get background information for using DHCP in general, plus complete information about the Windows 2000 use of DHCP. For those interested in what's on the horizon, the author steps up to the plate with an analysis of the future direction of DHCP and Windows support for IPv6.

DNO the SEO Revolution: A Detailed Guide for Achieving Permanent Page-One Rankings for Under $100
by Robert McAndersonThe total number of searches conducted across all search engines in 2011, will exceed 300 Billion and will cost companies competing for these page-one listings in excess of 50 Billion Dollars. DNO the SEO Revolution is a how-to-guide for achieving Permanent page-one rankings for under $100. This one extraordinarily simple idea will shatter traditional SEO concepts allowing every reader the opportunity to gain multiple Page One Rankings. I know because I have achieved multiple rankings for my own company and a select number of customers who participated in our trials. Achieving the top three listings on Page One of Google for under $100 is an amazing accomplishment but for them to be permanently listed and not be under threat from competitors who are prepared to pay more for the ranked position is extraordinary. The use of SEO, PPC and SEM to achieve a Page One Google Ranking are expensive but more importantly they offer no permanency. Keyword auctions that encourage competitors to pay a higher price for the number one ranked position are insane and it is time to do things differently. Remember Einstein said, “The definition of insanity is doing the same thing over and over again and expecting a different result.” Act now before your competitor does or face the consequences of their domination over you.
