TCP/IP is commonly known as the Internet Protocol Suite. Messing up with TCP/IP settings also cause problems and errors while accessing the Internet.

Do you get this error message even when you are connected with your dial-up, ADSL or cable Internet connection?

Is your Internet Connection Sharing (ICS) service or Windows Firewall terminated frequently?

This can happen when your TCP/IP stack Winsock settings may be corrupted. These get corrupted owing to virus, malware infection, installation of anti-spyware software or ill-functioning of anti-spyware/anti-virus software.  

Another problem that you may encounter is that Windows Vista is unable to get IP from a DHCP server.
