The task is works locally but not work in remote

This task include one batch file that can find patches in client computer by remote. I build this batch file as package into ALtiris 7.5.

Now the issue is run batch file in my hard disk by manual, everything is fine. For example, will showed "PC1234, 3065822 Patch found".  I checked PC1234 by remote, the 3065822 patch is installed.

However If I use job task and push this package to my computer (I want this task can automatic run in weekend), then will showed "PC1234, 3065822 Patch does not exist ".

This is code

@ECHO OFF

SETLOCAL

set LOGFILE_DATE=%DATE:~6,4%.%DATE:~3,2%.%DATE:~0,2%

set LOGFILE_TIME=%TIME:~0,2%.%TIME:~3,2%

set LOGFILE=log-%LOGFILE_DATE%-%LOGFILE_TIME%.txt

rem log-2014.05.17.txt

echo %date% : %time% > %LOGFILE%

set PATCH=3078071

for /f %%i in (workstations.txt) do (Call :CHECK %%i)

Goto End

:CHECK

Set COMPUTERNAME=%1

:PING

ping %COMPUTERNAME% -n 1 > .\temp\Ping.txt

find /I "out" .\temp\Ping.txt > .\temp\Reply.txt

if %errorlevel% == 0 Echo %COMPUTERNAME%, is Offline >> %LOGFILE% & Goto END

find /I "check" .\temp\Ping.txt > .\temp\Reply.txt

if %errorlevel% == 0 Echo %COMPUTERNAME%, Host is Not Found >> %LOGFILE% & Goto END

REM # Determine patch

:Search Pathch

wmic /node:%COMPUTERNAME% qfe | find /I "%PATCH%"

REM # IF ERRORLEVEL = 0 it is there

IF %ERRORLEVEL% == 0 (GOTO REPLACE_FILES2) ELSE (GOTO LOOP)

:REPLACE_FILES2

Echo %COMPUTERNAME%, %PATCH% Patch found >> %LOGFILE%

GOTO END

:LOOP

Echo %COMPUTERNAME%, %PATCH% Patch does not exist >> %LOGFILE%

:END

I think this code cause issue "wmic /node:%COMPUTERNAME% qfe | find /I "%PATCH%""

However spent couple hours, can't fix this issues.

Please help me, thanks.
