Hello everyone, my cmd under Windows 7 can't ping, netstat and other network commands seem to be unusable, but commands like cd\ and dir can be used. When pinging, it shows that it is not an internal command or an external command.

I set the environment variables when installing Java recently. Does that have something to do with it? I remember it used to be okay.

Oh, you wouldn't have deleted the original things in the path when setting the JAVA environment variables and changed it to the path of your JAVA, right??

You should edit it, separate with semicolons and add the path of your JAVA. I don't know the WIN7 system path, it should still be %windir%\system32, right? Just find that path and add it in.

Enter "set" in the command to check the "path" part of the variables

Oh my god, did you delete the original content in the path when setting up the Java environment variables and replace it with the path to your Java?

Hehe, you're right. I also had this thought at the beginning, but then I didn't think too much and just overwrote it with the Java path. Now I've changed the path to: %JAVA_HOME%\bin;%SystemRoot%\system32;%SystemRoot%;%SystemRoot%\System32\Wbem. It's already working. Thanks!~~
