Repair and Reset Windows Vista TCP/IP Winsock Catalog Corruption
TCP/IP stack Winsock settings in Windows Vista may get corrupted, causing errors and problems with Internet connectivity. Corrupt Winsock or Windows sockets configuration can be due to a lot of reasons such as installation of a networking software, or due to virus, trojan or malware infection, or sometime even due to disinfection of spyware by security software.
When Winsock corrupts, the networking errors that you may face include unable to surf the Internet with “Page cannot be displayed” error message in Internet Explorer or AOL even though the DSL/ADSL/cable Internet connection is connected. Sometimes, Windows Firewall/Internet Connection Sharing (ICS) service is terminated as well.
To repair and reset the Windows Vista
- Click on Start button.
- Type Cmd in the Start Search text box.
- Press Ctrl-Shift-Enter keyboard shortcut to run Command Prompt as Administrator. Allow elevation request.
- Type netsh winsock reset in the Command Prompt shell, and then press the Enter key.
- Restart the computer.
What netsh winsock reset command does are it resets Winsock Catalog to a clean state or default configuration. It removes all Winsock LSP (Layered Service Providers) previously installed, including the potential malfunctioned LSP that causes loss of network packets transmission failure. So all previously-installed LSPs must be reinstalled. This command does not affect Winsock Name Space Provider entries.
Note: To check which LSPs installed on your Vista system, use netsh winsock show catalog command.
It’s also possible to reset TCP/IP Internet Protocol stack.

If you get the “requires elevation” message, find Command Prompt in Start > All Programs > Accessories; right-click and select Run As Administrator.

I’m a little lost here…after typing Cmd into the search thing, I don’t have time to type ctrl-shift-enter. A black box just automatically pops up. I’m not sure if that is what’s supposed to happen, I’m not a computer genius or anything…
Is the black box the Command Prompt Shell?

Hello, I’m a little bit lost here.. I dont know where to continue searching heres my issue:
I cant access internet from any Internet Based Software EXCEPT for IE7.
I mean I open Firefox and cant even access my Router HTTP frontend (192.168.1.1) and when I close any internet program (FF, WLM, Skype.. etc) The program closes and then a crash message pops-up and Windows alerts me that the program has been shut down to prevent data execution (DEP). But IE works “perfect” and donsent crash.
Does anyone know what’s all this about?
Im running Vista Ultimate x64 and connecting through a Modem+router setup.
Thanks in advance.

This fix worked perfect and took only 5 minutes to complete. The only other thing I did was boot in Safe Mode first (press F8 at pc boot up and select boot in Safe Mode). I’m truely grateful you took the time to add this fix online – Thank you, God Bless!
I had been working on this issue for many hours prior to. My pc had all the noted symptoms and booted up slow as it was trying to start Windows Services that would not come up. Everything was a mess. These steps completed perfect and upon restart my pc came up as if someone turned a light on, truely amazing. thanks again, gg

This post is great! It’s also taking something that isn’t very common knowledge and relating it in a way that’s easy for most users to understand. Great work.
Keep it up.

Oh man!! You have no idea how badly you saved my life. I had preinstalled Vista machine; I installed a parental control software “Cybersitter”. The stupid software worked fine for a few weeks, then totally messed up my internet connectivity; which wouldn’t work even after uninstalling it. I’ve been looking for a simple yet effective solution for months now! Thanks a mil! I am going to post this link on some of the Cybersitter “help” sites.
Grateful.
