'ping' is not recognized as an internal or external command etc

[Christopher Woods (CM)]

Hi Chris,

Check your PATH. Something may have removed the C:\Windows\System32\; 
entry from its start. What you're looking for is in System Properties, 
Advanced tab, Environment Variables.

If you're using Windows 7 as a standard user with UAC enabled, once in 
the box you will find you can't actually edit the PATH. (Of course.) To 
do this you need to open the dialog elevated through UAC; in the Control 
Panel (System category) choose "Advanced system settings" - which should 
have the UAC shield next to it - then choose "Environment variables".

If you go from the Start menu and type "environment" it'll offer you two 
selections, both of which open the same box -- however only the option 
explicitly marked "Edit the system environment variables" will open UAC 
elevated.

This is what my PATH looks like (Windows 7, pretty new installation with 
just dig for Windows installed as extra):

%SystemRoot%\system32;%SystemRoot%;%SystemRoot%\System32\Wbem;%SYSTEMROOT%\System32\WindowsPowerShell\v1.0\;C:\dig;

To verify that this is the problem, before you edit your PATH open a DOS 
prompt and cd to C:\windows\system32 . Can you invoke ping manually from 
there? How about if you cd \ back to the root? If it works there then 
something else is afoot and it sounds like a script error. Otherwise, 
it's your Windows PATH and you should go doublecheck it's not been altered.


Cheers
Chris
