I have a problem running DOS commands when opening a cmd window. I open the
window and try to execute a command such as 'ping' and receive the following
error;

'ping' is not recognized as an internal or external command, operable
program or batch file.

However, if i type the full path c:\windows\system32\ping i can get the
program to run

Please let me know fast the solution

Open a cmd window and type the word path and hit enter.
It should show you one or more paths to various folders, separated by
semicolons. One of those paths should be c:\windows\system32.

If that path is not there, you should be able to google for info on
how to add it to your path or let us know and someone should be able
to help you add it in a way that it will be persistent even after
rebooting. I can't remember the details right now.

Do like Paul says, and open a CMD window and type PATH to see what the
current environment variables are.

If they are missing, or pointing to the wrong places, you can change
them as follows:

- Right-click on Computer and select Properties.
- Click on "Advanced System Settings". You will needs to respond to a
UAC prompt.
- Click on "Environment Variables".
- Double-click on PATH, and check that you have the following paths
entered (Without the quotes) : "_%SystemRoot%\system32_",
_\"%SystemRoot%_" and _\"%SystemRoot%\System32\Wbem_"
- Click OK for all dialogs.
- Reboot the computer
- Try the PING command again in a CMD window. If it still does not
work, then the file may have been deleted. Run an Admin-level CMD
window, and type "SFC /scannow" (without quotes) to try an fix the
problem.*Warning:* If you improperly change the PATH variable, you could alter
the behaviour of more than just Windows itself. Use caution, and always
make a note of what the original value was before making any changes, in
case you ned to get back.

OK, I'm a little dense
In system properties, I go to the 'advanced' TAB.
I click 'environmental variables'.
PATH is incorrect, so I click 'edit'.
I then type in all the stuff you show in quotes, without the quotes.
my question is ...does all that go in PATH with the commas?

Each entry in PATH must be separated by semicolons, like this:
"%SystemRoot%\system32;%SystemRoot%;%SystemRoot%\System32\Wbem"

What happens when you activate this admin account that always has full admin
rights?

Right, let's se if we can help here.

- Click "Start"
- Right-click on "Computer", then select "Properties"
- In the left pane, click "Advanced system settings" (You'll need to
respond to a UAC prompt)
- In the "Advanced" tab, click "Environment Variables"
- Under "System variables", find the "Path" entry, and then make sure
that "%SystemRoot%\system32;%SystemRoot%;%SystemRoot%\System32\Wbem"
is there (without quotes). If you're not sure, copy and paste the
entire "path" value into a new post here so we can see what is there.

If you don't want to go the above route, then try this:

- Open a "CMD" window as you normally would. Make a note of which
folder is current in the command window.
- type "set >vars.txt" (without quotes) and press <ENTER>
- Close the CMD window
- Open Explorer, and go to the folder you noted earlier in step 1
- Attach the VARS.TXT file to a reply post here so we can see what
your environment variables look like.

In either case, the idea is to see what you have for PATH, and from
there help you to make whatever corrections you require (if any).

The problem are the underscores and the back-slash b4 the environment
variable %systemroot% (which = c:\windows - for most w/ c: as OS drive).
Change your's in red to what appears in blue -

Code:
--------------------

_%SystemRoot%\system32_;_\%SystemRoot%_;_\%SystemRoot%\System32\Wbem_

--------------------

Code:
--------------------

%SystemRoot%\system32;%SystemRoot%;%SystemRoot%\System32\Wbem

--------------------

Thanks my dear, I hv been able to run attrib in th command prompt but it
is only showing the attributes of c: while in other drives it is showing
file not found;;;moreover when i try to run the Ping while being
connected to the net;; it asks to host the specified ping until the
connection is stopped and then displays th number of commands
