Cannot Ping from the command line.

Posted on 2004-10-06
Last Modified: 2010-04-14
Just recently I can no longer use the networking functions from the command line.  I can still use the "ping" command, and tracert commands if I browse directly to the Winnt/system32 directory and run them from there, however I can not just type it into the command window as I used to.  Is there a patch or something that took this functionality away?  I receive the error code 'Ping' is not recognized as an internal or external command.

has something tinkered with your PATH environment variable?

from dos, type SET and it should include something like this:
Path=C:\Program Files\NetworkSimplicity\ssh;C:\WINNT\system32;C:\WINNT;C:\WINNT\
System32\Wbem;C:\Program Files\Symantec\pcAnywhere\;C:\Program Files\Resource Ki
t\;C:\Program Files\Support Tools\

and c:\winnt\system32 should be in there

also can be seen under My Comp.. Properties.. Advanced.. Environment Variables - can edit it back in again here.

Nice tip, I looked and under path it is there everything is there with the exception that there is also a Perl directory in the front.

All put certainly an error in the path statement.  If you don't see it yourself, post the contents of the %path% variable here.  Just type

set path

in a command prompt and post the result.

The order's not important: from memory, when you enter a command, it tries the current folder, then the root, then works it's way through the PATH statement in order, checking each location for the command you entered.  
You may get a nanosecond or two faster response by moving c:\winnt\system32 to the start, but I wouldn't bother....

some googling turned this up
where someone else has a perl entry at the start, which caused their problem.  Your entries are all separated by semicolons ; yep??
heck, delete the perl entry, just for fun (note down what it was, first!), and let us know the outcome.
you may need to restart after making a change, for the new settings to take effect.

Well thanks, after you said that I remembered that prior to this problem I had installed the windows 2000 optional resource kit so that I could use the clear screen saver on my servers.  That is what installed the Perl into the path.  I set the path to Perl at the end and now my Ping and tracert and all my other commands work from the command line again.

just an afterthought - can you still see the utilities in the perl folder?  just wondering if we should check out possible limitations on the length of the path statement....
