In 2010, there were 8 new posts, growing the total archive of this blog to 73 posts.

The busiest day of the year was December 21st with 70 views. The most popular post that day was Clearing Windows Update Cache Upon Update Failure .

Where did they come from?

The top referring sites in 2010 were social.answers.microsoft.com, social.technet.microsoft.com, google.com, tek-tips.com, and google.co.in.

Some visitors came searching, mostly for limitlogin, limit login, standard tcp ip port missing, ntfrs, and clear windows update cache vista.

Introduction to Google Public DNS

Filed under: My Knowledge — Rahul Patel @ 11:42 am

As web pages become more complex and include more resources from multiple origin domains, clients need to perform multiple DNS lookups to render a single page. The average Internet user performs hundreds of DNS lookups each day, slowing down his or her browsing experience. As the web continues to grow, greater load is placed on existing DNS infrastructure.

Since Google’s search engine already crawls the web on a daily basis and in the process resolves and caches DNS information, we wanted to leverage our technology to experiment with new ways of addressing some of the existing DNS challenges around performance and security. We are offering the service to the public in the hope of achieving the following aims:

* Provide end users with an alternative to their current DNS service. Google Public DNS takes some new approaches that we believe offer more valid results, increased security, and, in most cases, better performance.
* Help reduce the load on ISPs’ DNS servers. By taking advantage of our global data-center and caching infrastructure, we can directly serve large numbers of user requests without having to query other DNS resolvers.
* Help make the web faster and more secure. We are launching this experimental service to test some new ways to approach DNS-related challenges. We hope to share what we learn with developers of DNS resolvers and the broader web community and get their feedback.

Google Public DNS is a recursive DNS resolver, similar to other publicly available services. We think it provides many benefits, including improved security, fast performance, and more valid results. See below for an overview of the technical enhancements we’ve implemented.

Google Public DNS is not, however, any of the following:

* A top-level domain (TLD) name service. Google is not an operator of top-level domain servers (generic or country-code), such as Verisign.
* A DNS hosting or failover service. Google Public DNS is not a third-party DNS application service provider, such as DynDNS, that hosts authoritative records for other domains.
* An authoritative name service. Google Public DNS servers are not authoritative for any domain. Google maintains a set of other nameservers that are authoritative for domains it has registered, hosted at ns[1-4].google.com.
* A malware-blocking service. Google Public DNS does not perform blocking or filtering of any kind.

To try it out:

* Configure your network settings to use the IP addresses 8.8.8.8 and 8.8.4.4 as your DNS servers or

Critical security hole in Adobe Acrobat PDF readers

Filed under: My Knowledge — Rahul Patel @ 9:17 am

Adobe has issued a security alert after a critical zero-day vulnerability was discovered in their popular PDF reading program which could allow hackers to take control of computers.

The risk is that hackers could deliberately construct a malformed PDF file that would trigger the vulnerability, allowing them to open a backdoor and run malicious code on your computer. This would mean that criminals could, for instance, spam out a PDF file that would infect your PC, or plant malicious PDF content on a website.

As PDF files are so widely used on the internet, and regularly exchanged to share information, there is an obvious concern that hackers may be quick to take advantage of this vulnerability.

The vulnerability, which is not limited to Windows users but also affects Mac and Unix users, means that Adobe users are being advised to disable JavaScript in Adobe Reader and Acrobat until a proper fix is available.

Adobe advises that JavaScript can be disabled by following these instructions:

1. Launch Acrobat or Adobe Reader.
2. Select Edit/Preferences
3. Select the JavaScript Category
4. Uncheck the ‘Enable Acrobat JavaScript’ option
OR

Converting Dynamic Disks Back to Basic Disks

Filed under: My Knowledge — Rahul Patel @ 11:14 am

Windows 2000, XP and 2003 provide a feature called Dynamic Disks. A dynamic disk can contain simple volumes, spanned volumes, striped volumes, mirrored volumes, and RAID-5 volumes. When using dynamic storage, you can perform disk and volume management without the need to restart the computer.

Once the change has been made to Dynamic Disks, they cannot be changed back to Basic Disks without deleting the partitions and rebuilding the disk. This can be troublesome, thankfully there is a way to hack it back to a Basic Disk.

Caution: Make sure you have a full, verified backup of all your data before you proceed. If you make an error during this procedure the disk will become corrupt and data loss can occur. Before you begin you will need a tool from the Windows 2000 SP4 Support Tools called DskProbe.

DskProbe is a sector editor tool that allows you to edit, save, and copy data on a physical hard disk. Once you have downloaded and installed the support tools, run DskProbe.exe from C:\Program Files\Support Tools.

Note: Windows 2003 Support Tools includes DskProbe 2.

-The GUI is changed but the steps are the same. With DskProbe running click on Drives and select Physical Drives.

-In the Open Physical Drive window double click the drive you wish to edit and then click on Set Active. Once the drive has been set as active, close the window.

-Next click on Sectors and select Read.

-Enter the Starting Sector as 0 and the Number of Sectors to 1 then click Read.

-Scroll down until you locate sector 01C0 and the third byte from the left should read 42. Along with being the answer to Life, the Universe and Everything else, it is also what identifies this as a dynamic disk.

-Change this byte to 07.

-Next click File and then select Exit. You will be prompted to save the changes made.

-Click yes, and when DskProbe closes reboot the machine. Once the computer has rebooted open up Disk Management and the drive should be restored back to a Basic Disk. You will have to do this for each partition on the disk.

Microsoft TechNet Sysinternals Online Toolset

Filed under: My Knowledge — Rahul Patel @ 10:23 am

Microsoft is testing a service that gives IT managers anywhere access to all the free Sysinternals diagnostic and troubleshooting utilities from any machine connected to the Internet.IT administrators no longer need to download and unzip the tools.They can run them from any Web location.
The idea is to provide full web-based access to the Sysinternals Toolset without unzipping files, etc.

Microsoft releases first iPhone app

Filed under: My Knowledge — Rahul Patel @ 1:30 pm

Engineers in the company’s Live Labs have released the company’s first application for Apple’s popular smartphone–even before making it available on Microsoft’s own mobile platform. Seadragon Mobile, which was added to Apple’s App Store on Saturday, is a free image-browsing app that allows users to quickly “deep zoom” images while online and is intended to demonstrate what is possible with a mobile platform.

Seadragon is the backbone for Microsoft’s Photosynth, which allows users to take a grouping of photographs and stitch them together into a faux 3D environment. Other iPhone apps are reportedly in development in Redmond; Microsoft’s Tellme unit was expected to release the company’s first iPhone app in the form of a voice-activated search for a variety of phones, including iPhone and BlackBerry.
