How to Repair Damaged Winsock2
 

When we try to release and renew an IP address using IPCONFIG command then sometimes we get an error massage which says:

An error occurred while renewing interface 'Internet': An operation was attempted on something that is not a socket.
Again Internet Explorer may give the following error message:
The page cannot be displayed Additionally, you may have no IP address or no Automatic Private IP Addressing (APIPA) address, and you may be receiving IP packets but not sending them.

Actually this error occurs if the system winsock2 file is damaged.

To confirm that winsock2 file is damaged. Follow the steps below:

Winsock Test Method 1
Run netdiag /test:winsock
After execute his command
Lastly tell Winsock test ..... passed

Winsock Test Method 2
go to Run and type Msinfo32
Click on the + by Components
Click on the by Network
Click on Protocol
There should be 10 sections if the Winsock2 key is ok
MSAFD Tcpip [TCP/IP]
MSAFD Tcpip [UDP/IP]
RSVP UDP Service Provider
RSVP TCP Service Provider
MSAFD NetBIOS [\Device\NetBT_Tcpip...
MSAFD NetBIOS [\Device\NetBT_Tcpip...
MSAFD NetBIOS [\Device\NetBT_Tcpip...
MSAFD NetBIOS [\Device\NetBT_Tcpip...
