The process of installing Windows 7 involves a stage in which end users need to Set a Network Location. The SNL dialog window can be revisited after deployment, and the settings altered. In this context, location is key. In order to simplify the network configuration, Windows 7, just as Windows Vista before it, allows users to set up a network connection in accordance to location. The SNL dialog offers three different network locations: Public, Work and Home. What it does is that when the computer detects a network connection, options are provided for the user to help define and apply appropriate network settings automatically.
User interaction is only necessary when choosing among Home, Work or Public locations, as Windows 7 does all the heavy lifting. But you can’t even tell there’s any heavy lifting involved as the configuration process is extremely fast, and I for example, have yet to see it fail even once, after countless installs of the platform in pre-Beta, Beta, RC and pre-RTM stages.
In all fairness, the Windows 7 client comes with an additional option for network location, namely Domain. However, Domain is reserved for enterprise environments and is out of the reach of end users. The option is controlled entirely by a network administrator, users cannot opt to take advantage of Domain by themselves or alter the configuration. Read More»

A DNS server translates a human address like google.com into a numerical IP address so your computer can take you to the right site. Usually, this takes a few hundred milliseconds to complete so it’s barely noticeable, but over time, these milliseconds can really build up. Also, your ISP’s DNS server isn’t always reliable as witnessed by Comcast subscribers recently when their DNS server failed, leaving customers unable to access Google and other sites. By using OpenDNS and FastCache, you can solve the two problems of reliability and speed.
OpenDNS runs a distributed network of DNS servers so using it is more reliable. It filters out bad addresses so phishers and spammers can’t direct you to their site. OpenDNS also detects typos in the URLs you enter so entering craigslist.og leads you to craigslist.org.
A piece of software called FastCache takes care of the problem of speed. It stores the IP address that is returned by your DNS server so your computer doesn’t have to request it every time you want to go to a particular site, saving a few hundred milliseconds each time. Read More»

Jason 1. Your computer isn’t turning on? “Oh, no!” You think, “I’d better get a new one!” STOP right there. Before you get too frustrated, be sure you have checked that the power cord is actually plugged into your wall socket properly. You may think it sounds silly, but believe me, it’s more common than you think even for the computer savvy. If your computer is connected through a power board, you should try plugging it directly into the wall (note for the safety conscious: by plugging the power cable directly into the wall, you lessen the chance of power failure and damage to your machine). Another reason that your PC may not start is if you have made any repairs or modification to your machine. You may have unwittingly pulled out a connect plug; check all connections.
2. If your computer is starting but is spitting error messages at you, then you might need to take out any memory modules such as RAM and then reset them by plugging them back into different RAM slots.If you get an error such as ‘Unexpected Interrupt in Protected Mode,’ then there is a problem with the settings you have entered in BIOS. To fix it go into BIOS and set it to default settings. If the problem still won’t go away, then you must remove the CMOS chip on your motherboard then put it back in to clean BIOS completely.

I used to rely on Norton’s Speed Disk, then, eventually Perfect Disc and Diskeeper to optimize my HDD. Defragmenting is the idea- an antiquated process of reorganizing bytes on spinning platter so that each file is grouped into contiguous locations on the disk. Many still believe that defragmenting hard disk drives on a regular basis keeps PCs operating at peak performance. But that idea is behind the times.
Defragmenting served its purpose back when folks chugged along on 486DX4 PCs powered by 5400rpm drives. Now those where slooooow drives and extra spindle movements arising from defragmentation truly hobbled the system. But that’s no longer the case. Today, 7200-RPM hard-disk drives with monster seek and latency times are the bare minimum; most brag a 16-MB cache buffer. Couple that with Windows XP’s high speed NTFS and you’ll quickly discover that defragmenting no longer makes much improvement, if any, to system performance. I say this after thorough experimentation on my QuadCore running on a 10,000RPM Western Digital Raptor. Read More»

TCP/IP, an acronym for Transmission Control Protocol/Internet Protocol, is a suite of protocols supported by Microsoft with the Windows family of platforms. Essentially, through its components, TCP/IP is used for communications on both private networks and on the Internet. As far as the world wide web is concerned, the most common aspects of TCP/IP are IPv4 (Internet Protocol version 4) and IPv6. The Redmond company is offering extensive documentation on TCP/IP as it is supported in Windows Vista, Windows Server 2008, Windows Server 2003 and Window XP. TCP/IP Fundamentals for Microsoft Windows is available for download.
“This online book is a structured, introductory approach to the basic concepts and principles of the Transmission Control Protocol/Internet Protocol (TCP/IP) protocol suite, how the most important protocols function, and their basic configuration in the Microsoft Windows Vista, Windows Server 2008, Windows XP, and Windows Server 2003 families of operating systems,” revealed Keith Combs, Microsoft IT Pro Evangelist, citing an excerpt of the documentation’s description.

Jason Compared to their predecessors, Windows XP (on the client side) and Windows Server 2003 (on the server side), Windows Vista and Windows Server 2008 bring to the table evolved networking technologies. Illustrative of the network enhancements of the latest client and server operating systems from Microsoft are the high-performance, auto-tuning TCP/IP stack and the integrated support for both IPv4 and IPv6. According to the Redmond company, Vista and Windows Server 2008 both include a redesigned TCP/IP stack offering functionality not only for Internet Protocol version 4, but also for Internet Protocol version 6, as well as ensuring a smooth transition from IPv4 to IPv6.

Jason Windows XP is configured to help you take care of networking. It uses the TCP/IP protocol for networking in workgroups, or what you might call small office or home networks that do not use a dedicated server.
The problem is that automatic IP addressing can be slow. When your computer boots, it has to query the network to see what IP addresses are already in use and then assign itself one. If you want to speed up the boot time a bit, consider manually assigning IP addresses to all computers on the network. This way, the network computers do not have to worry about locating an automatic IP address. Because one is manually configured, the operating system doesn’t have to spend time solving this problem.
