"nbtstat -n" works from Command prompt but not from batch script?

[tobwz]

If I enter in Command Prompt the following command:

Code: Select all

nbtstat -n

to check NetBIOS status then it works.

If I execute exactly the same command from a DOS batch script I was told:

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

Whats wrong?

cmd will use the system variables %path% and %pathext% to search for nbtstat.exe.
You have probably changed these system variables in your script or used variables with these names.
Without the correct path large parts of cmd will cease to function, for example, find, notepad, reg are all external programs that rely on the systempath.

@OJBakker:

I disagree.

BOTH Command Prompt and batch scripts execution use the SAME Environment (variables).

So if I would change %PATH% and %PATHEXT% this would affect BOTH methods.

BUT: Command Prompt direct execution works while Batch Script execution NOT.

So it must be another reason

Is this an access permission problem?

[OJBakker]

No, Command prompt and scripts START with the same environment.
Try this script.

Code: Select all

@echo off
setlocal
%systemroot%\system32\where nbtstat
nbtstat -n
path=%TEMP%
%systemroot%\system32\where nbtstat
nbtstat -n
endlocal
pause

Please post the code that shows your problem, so we don't have to keep guessing for the cause of your problem.

Ok, at first here is the batch script ShowNetBiosState.bat:

Code: Select all

@echo off
cls

echo If you get any response other than "Failed to access NetBT driver -- NetBT may not be loaded" means NetBIOS is enabled
echo.

nbtstat -n

echo.

pause

When I double click on the batch script in fails with the error message mentioned in my first post

If I open a Command Prompt, then navigate to exactly the directory where the batch script is stored (D:\tools\net services\show state\" and finally enter the batch file name and hit RETURN the same, unmodified batch script runs fine.

[OJBakker]

add the following lines to your batch file.

Code: Select all

echo path: %path%
echo pathext: %pathext%
%systemroot%\system32\where nbtstat

Run this both from prompt and from windows.
Compare the output from both and that will show you why nbtstat can not be found.

First, you said:

nbtstat -n

If I execute exactly the same command from a DOS batch script I was told:

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

Whats wrong?

After that, you add:

When I double click on the batch script in fails with the error message mentioned in my first post

If I open a Command Prompt, then navigate to exactly the directory where the batch script is stored (D:\tools\net services\show state\" and finally enter the batch file name and hit RETURN the same, unmodified batch script runs fine.

From this description, I assume that the nbtstat command is not located in a directory of %PATH% variable, but in the same directory of the Batch script ("D:\tools\net services\show state\"). If so, you should:

• Copy or move the nbstat(.exe?) command to a directory in %PATH%, or
• Add the following command at the beginning of the Batch file:

  Code: Select all

  cd "%~P0"

I solved it as follows:

I reviewed my full PATH and PATHEXT environment strings and dropped (out of approx 40 entries) around 15 deprecated paths.
They were added in past but not removed when I uninstalled the corresponding software.

Then (after clean-up) I rebooted....and it worked.
This is curious

Thank you anyway
