pingwww.google.com
ping.exewww.google.com
%windir%\system32\pingwww.google.com
%windir%\system32\ping.exewww.yahoo.com
%systemroot%\system32\pingwww.google.com

Invoke ping this way:
Start /Run /Cmd Ping
What you did was
Start /Run Ping
Which displays as you stated.

See if one of these commands works.
ping /?
Should show ping Help.
%systemroot%\system32\dllcache\ping.exewww.yahoo.com
%systemroot%\ServicePackFiles\i386\ping.exewww.yahoo.com
If you had a ping.com, you'd get an error message when using ping with no
extension or path.
If the path was messed up, you'd get a "is not recognized" message.
Sounds like ping.exe might be messed up. If it works with the dllcache or
i386 path then WFP can fix it.
ping.exe normally exists in
C:\WINDOWS\system32
and
C:\WINDOWS\system32\dllcache
or
C:\WINDOWS\ServicePackFiles\I386
The ping.exe in C:\WINDOWS\system32 is the one that gets used. The other
one is for backup. If Windows File Protection is working correctly, the
following should help.
Try this.
Start | Run | Type: system32 | Click OK |
Size the window so you can also see your Desktop.
Scroll down to ping.exe.
Left click and drag ping.exe to your Desktop.
Wait just a minute.
Now scroll down clear to the bottom of system32.
Is there a new ping.exe there?
If there is a new ping.exe delete the one on your Desktop.
Close system32.
If there is NOT a new ping.exe drag the one on your Desktop back into
system32.
Close system32.
If there is a new ping.exe in system32, you'll see something similar to
this in the Event Viewer under System, listed as Information; Windows File
Protection:
Event Type: Information
Event Source: Windows File Protection
Event Category: None
Event ID: 64002

Description:
File replacement was attempted on the protected system file
c:\windows\system32\ping.exe. This file was restored to the original version
to maintain system stability. The file version of the system file is
5.1.2600.2180.
If that doesn't help expand a copy of ping.exe from the XP CD.
Ping.exe is on your XP CD listed as PING.EX_ in the I386 folder. The
underscore (_) means that the file is compressed. The compressed file needs
to be expanded to be of any use. To expand it to the proper location...
Insert your XP CD into your CD drive and enter (Copy and Paste) the
following command into the Start | Run box:
expand D:\I386\PING.EX_ c:\windows\system32\ping.exe
Hit your ENTER key or click OK.
NOTE :
Change D to your CD drive letter if different.

Mike said:Something weird happens.
When I copy the "ping.exe" from "c:\Windows\System32\" to some other
folder, like "d:\". Then I invoke it like " d:\ping.exe www.hotmail.com"
, I can see the output correctly.
Why the same "ping.exe" will behave differently in different folers ?
I don't quite get it.
Hi Mike
Does it work correctly if you specify the *literal* path, like this:
C:\Windows\System32\ping.exewww.hotmail.com
while it doesn't if you use a system variable such as %systemroot% or
%windir%?
If so, it's likely the data type of the Registry entry for your Path is
wrong -- usually REG_SZ when it should be REG_EXPAND_SZ. The link that
Wesley gave you to Bill Stewart's site has a program called Fixpath that
will change it for you, and instructions on how to do it manually if you
prefer:http://internet.cybermesa.com/~bstewart/cmdprompt.html#6

No, it still doesn't work if I specify literal path. It's so weird.

Hi Mike
Okay. . . so we have established:
Your Path looks correct;
The data type of the Path entry in the Registry is correct;
There is nothing wrong with the actual ping.exe file in
\Windows\System32 (since when you copy it to D:\, it works).
The only thing I can think of is that something is blocking the ping
command when run from that location. Have you checked your firewall in
case you have accidentally set up a rule to do that?
