Recently, I was asked the following question: “We plan to implement Windows 7 in our network very soon. We want to use Windows 2003 Domain Controllers for the next couple of years. 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.

Part 11 of this blog series looked at Class Based Weighted Fair Queuing. This blog will explore the next queue mechanism; Low Latency Queuing (LLQ). As seen in the previous section of this QoS series, CBWFQ provides user defined traffic classes allowing for more con...

Part 10 of this blog series looked at Weighted Fair Queuing, so now we move on to the next queue mechanism; Class Based Weighted Fair Queuing (CBWFQ).CBWFQ provides user defined traffic classes allowing for more control and functionality then weighted Fair Queuing. C...

I recently was presented with the challenge of logging ALL of the pertinent connection, disconnection, and termination messages associated with the Cisco SSL AnyConnect client without overwhelming the syslog capture display with extraneous messages. This blog will br...

WFQ is a flow-based method that sends packets over the network and ensures packet transmission efficiency which is critical to the interactive traffic. This method automatically stabilizes network congestion between individual packet transmission flows.

In part 8 of this blog series congestion management and its four main queuing methods were explored. This post will look at the first of four queuing methods: First In First Out (FIFO) queuing. To refresh our memories, congestion can occur anywhere within a network,...

In light of the recent tragic events in Haiti, it might be a good time to review some of the requirements for a well designed Uninterruptible Power Source (UPS) to be included in all of our critical network installations. As a CCNA, we are called upon to help maintai...

In part 8 of this series we are going to unravel the mysteries of congestion management and its four main queuing methods.Congestion is the result of many factors and can occur in many places on the network. A few of the reasons for congestion are traffic aggregation...

Internet Protocol (IP) routing protocols have one primary goal: to fill the IP routing table with the current best routes it can find. The goal is simple, but the process and options can be complicated. Routing protocols define various ways that routers chat among th...

Project procurement activities are often managed by specialists. By this I mean that the procurement department takes over responsibility for purchasing and contract management from the project manager. As a result of this separation of responsibilities, the steps and stages of procurement are often poorly understood by PMs. In this and the next few blog submissions, I will attempt to shed light on procurement activities and relate these activities to the PMI PMBOK.
