The problem I have began when a "ConHook.B trojan attempted to install on my machine, but it supposedly was successfully removed at the time, 1/15/2008, according to the Windows Defender history log.
AVG Anti-virus, Ad-aware, Spybot, and Windows Defender scans all report no problems. I have run Registry Mechanic to clean the registry.
However the problem remains that I cannot connect to the internet. I first get a message that I am offline, and then when I try to connect again I get this message:
"Windows has detected a problem with the Winsock Provider Catalog on this computer. Would you like to reset the catalog to the default configuration?" If I click yes and restart the computer it does not change anything. If I click the "View last diagnostic run" I get the following information:
info All base service provider entries are present in the Winsock catalog.
info The Winsock Service provider chains are valid.
error Provider entry MSAFD Tcpip [TCP/IP] could not perform simple loopback communication. Error 10050.

Also I have found that my Windows XP firewall is not connected...it was before. I cannot start it in the services menu; when I right click on "Windows Firewall/Internet Connection Sharing " and press start, I get the following message:
"Could not start Windows Firewall/Internet Connection Sharing on Local Computer. Error 2001: The specified driver is invalid"
I tried to re-install the firewall according to these instructions from a microsoft kb article:
Method 1: Call the "Setup API InstallHinfSection" function to install Windows Firewall
To install Windows Firewall, follow these steps: 1. Click Start, click Run, type cmd, and then click OK.
2. At the command prompt, type the following command line, and then press ENTER:
Rundll32 setupapi,InstallHinfSection Ndi-Steelhead 132 %windir%\inf\netrass.inf
3. Restart Windows,
4. Click Start, click Run, type cmd, and then click OK.
5. At the command prompt, type the following command, and then press ENTER:
Netsh firewall reset
6. Click Start, click Run, type firewall.cpl, and then press ENTER. In the Windows Firewall dialog box, click On (recommended), and then click OK.
It did not help.
I have read several Microsoft Knowledge Base articles and tried many of the things they suggested.
I have reloaded IE7 default settings and cleared temporary files and restricted sites and trusted sites.
I have deleted the Winsock and Winsock2 keys, and then reinstalled TCP/IP as instructed.
I have typed "netsh winsock reset" at the command prompt & rebooted, but this does not help.
I also installed the net diagnostics tool from my XP disk. When I go to command prompt and type netdiag/test:winsock/v, I get this message:
"Failed to get information for a network adapter. The error occurred was: The pipe is being closed
<232> [Fatal] Cannot find the TCP/IP configuration from the registry.
I am in contact with Microsoft support by email, but it takes 1 to 2 days for a response each time, so it does not seem that they will be able to help me very quickly. My next step may be to re-install XP, but my disk is so old that it would take me many hours to re-install all the windows updates.
Any help is greatly appreciated. I have already seen a lot of great information on this forum.
