How do I know tcp/ip installed?

Any idea? Thanks

well if you can connect to the internet (which is how you got here to write this post) then you have tcp/ip installed. ;)

however if your talking about having tcpip installed in vb, then the closest thing would to use the winsock control. which you can add in the components window, and its under microsoft winsock control.

hope that helps :D

If you can ping 127.0.0.1 (localhost) TCP/IP is installed and working correctly. There might be a more elogant check using registry keys, though.

ping is the most reliable method because it checks that all the routing tables are set up correctly as well.
