The definition of cloud computing depends largely on whether you are a consumer or producer. The public cloud is geared more for the individual consumer or small company, while the private cloud is geared more for a medium-to-large company. In addition, the private cloud is branching out to incorporate the ability to have some data and applications serviced from the public cloud. This white paper examines the different types of cloud computing and shows what cloud computing can offer you.

The flexibility, reduced cost, and mobility of cloud computing have made the concept a hot topic. Before implementing this method of computing, however, it is important to consider the security of the "cloud." In this white paper, you will learn some of the risks and benefits of cloud computing to be sure it is the right solution for you.

Can we make the hundreds of new Group Policy setting available to Windows 7 Windows Server 2003 DCs?” This is not an unusual situation. Some organizations find they need to replace their desktop computers immediately because of age or obsolescence and others wish to upgrade to Windows 7 because of its superior security and performance. But there may be no budget or desire to upgrade to Windows 2008 or 2008 R2. Luckily, it is not difficult to adapt Server 2003 to work with Windows 7.

The subject of this week’s post was actually prompted by a question from a former colleague.  Soon after the PIX Firewall added support for IPSec Virtual Private Networks, a command was added to the command-line, sysopt connection permit-ipsec. This command was subse...
