Connection Timeouts When Using Multisubnetfailover=True

When you try to connect to Microsoft SQL Server 2012 through an AlwaysOn availability group listener from a client application, you may experience a logon time-out error message.

Connection Timeouts When Using Multisubnetfailover=True

This issue occurs because the Tdx.sys driver does not handle the Closesocket() function correctly when the function is called in the middle of a TCP/IP handshake.


After installing the below hotfix . I am able to connect to SQL database using “multisubnetfailover=true” without any issue.

Unlock your AT&T iPhone for free


After giving in to the pressure from consumers, AT&T finally started unlocking contract-free iPhones as of April 8th. Well for once, AT&T is actually going above expectations to make the process easier. You don’t even have to visit your local AT&T store to unlock the iPhone; you can do it online right from home.
First you’ll have to obtain your contract-free iPhone’s unique IMEI number. Jump into the Settings app, then General, then About. Scroll down and voila! First step complete. Next, log in to AT&T’s website with your credentials and bring up AT&T Wireless Support Chat, both of which I’ve linked to here for your convenience. Fire up a chat with one of the support representatives and request that your device be unlocked. As long as your iPhone was bought from AT&T, not locked into a contract, and you have your IMEI number handy, you shouldn’t have any problems.
The final step requires some reliance on Apple. AT&T pushes your request to Apple, then Apple has to email you the unlock code. It’s done within 72 hours, but it could take as little as an hour to receive the email. Before utilizing the unlock code, you’ll have to backup and restore the iPhone through iTunes. If all goes as planned, you’ll be able to roam freely with your unlocked toy.
It’s not too hard, but there’s a lot of opportunities for disaster here so stay cautious. If you’re feeling sociable today, you can always take the traditional route and visit your local AT&T store. Happy unlocking!


Windows 8 Release Date In India







Looks like, Microsoft has finally decided to release its killer OS just before the holiday season kicks off. The company announced the official availability of Windows 8 OS on October 26 via a blog post. 
The world’s largest software maker is pinning high hopes on Windows 8 platform. The eager firm is doing everything to make sure that its newest OS does well in the critical environment dominated by Apple and Google. Windows 8 plus office 13 is one of the bright examples that will surely lure buyers.
Windows 8 OS is designed to run on both tablets and traditional PCs. This could be the biggest test in front of Microsoft to prove its mantle in front of millions of hardcore windows users.
For the first time, Microsoft has decided to manufacture its own range of tablets running on Windows 8 to compete with iPad and Nexus 7. The software giant could announce the pricing and availability of Surface tablets in late October as well.
Intel Corporation, world’s largest chip manufacturer recently stated that more than 20 atom chip powered Windows 8 tablets will be available by the year end. 
The success of Windows 8 powered tablets is dependent upon the pricing set by the hardware manufacturers. By looking at the specifications required to run a Windows 8 tablet, it would be safe to say that the manufacturers are not in a mood to place their fancy tablets against Google Nexus 7 or Amazon Kindle Fire. 
Recently, Microsoft’s chief operating officer, Kevin Tuner made an unforgettable mark by saying that Apple’s idea of ‘Post-PC’ era doesn’t make any sense. He further said we would like to call this era as PC+ generation. 
It would be interesting to see the cat fight between two tech titans. Now, all eyes set on October 26.

Install OS X Snow Leopard in VMware Windows 7

The following step by step guide will help you in installing Mac OS X 10.6 Snow Leopard as a guest virtual machine in Windows 7. You’ll need to have a system with an Intel processor which supports hardware virtualization, original OS X Snow Leopard retail disk, VMware Workstation 7 and Windows 7, Vista or XP installed as host operating system. If you meet all these requirements, you can then install OS X Snow Leopard as a VM under Windows and can enjoy the best of both worlds.



Note: We don’t in anyway encourage downloading Apple software via file-sharing / torrent sites and run it in an virtualized environment under Windows. This guide is for informational purposes only. If you like OS X Snow Leopard, Get a Mac.



Step 1: Download and install VMware Workstation 7.
Step 2: Download pre-made modified version of Snow Leopard.vmdk and darwin_snow.iso files required to get this thing to work. Please don’t ask for the link to these files. You can find them easily elsewhere on the web.
Step 3: Start VMware Workstation and open up “Mac OS X Server 10.6 (experimental).vmx” file which you downloaded in Step 2.









Step 4: Click on”Edit virtual machine settings”, select CD/DVD (IDE) option from left hand side and then and select “Use ISO image file” option. Point it to “darwin_snow.iso” which you downloaded in Step 2.


Step 5: Now power on the virtual machine and hit “F8” key. You should now have a screen similar to the one shown below.


 
Step 6: Now you’ll have to point your virtual machine to OS X Snow Leopard retail DVD instead of “darwin_snow.iso”. To do this, right click on CD/DVD option found in lower right most corner of your VMware window and select settings.




Insert OS X Snow Leopard retail DVD in your DVD drive and select the “Use physical drive” option.
Step 7: Now go back and select “c” option (Boot DVD) from the prompt which you got in Step 5 to boot from the OS X retail DVD. OS X boot screen with Apple logo should now appear. If the boot screen doesn’t appear for you, try booting it in verbose mode by pressing “F8” key after selecting “c” option, and then enter “-v” (without quotes). This will enable the system to boot OS X DVD using verbose mode.




 
Step 8: Wait for a couple of minutes for the Installation Setup screen to show up. From here on, simply follow the onscreen setup instructions to install OS X Snow Leopard. Make sure you format your virtual hard drive in “Mac OS Extended (Journaled)” format using Disk Utility. Customize your installation with minimum set of printer drivers and language options for a lightweight trouble free installation experience.
Step 9: Once the installation is completed. System will automatically reboot. At this point, close your guest virtual machine and change your CD/DVD option again like you did in Step 2 to point it to “darwin_snow.iso”.
Step 10: Start the virtual machine again. Press “F8” key and select “h” option to “Boot first hard disk”. Voila! Snow Leopard should now be running live under Windows 7! [via ihackintosh]
Feel free to ask me any question should you run into any problem in getting Snow Leopard VM to work under Windows 7.
