Hi i am new to batch programming
I just need to:
1. start Windows Task Manager inside my batch file
2. list all active processes
3. discover the wanted-processes (check by doing netstat -ano is port no 1099 being used if yes the get the PID and find the name of the process)
4. kill it

soma

you can list processes with tasklist in XP. I guess its avaible in w2003 as well.

Anyway.. try this

::CODE
@echo off
for /f "tokens=1-5 delims= " %%a in ('netstat -o -n ^|find "1099"') do (set PID=%%e
call :KillPID)

:KillPID
taskkill /f /PID %PID%

it seems you know what's the process name by using netstat..here's a vbscript to kill process. Its just an example. Don't use svchost.exe in your case
[code]
strComputer = "."
Set objWMIService = GetObject("winmgmts:{impersonationLevel=impersonate}!\\.\root\cimv2")

Set colProcessList = objWMIService.ExecQuery _
("Select * from Win32_Process Where Name = 'svchost.exe'")

For Each objProcess in colProcessList
objProcess.Terminate()
Next
[/code]

Scr0Om:
If you used your batch script the 'find' command could output a line with "1099" as the PID, instead of the port. Its unlikely, but anyway to fix this you could use

@echo off
setlocal EnableDelayedExpansion
for /f "tokens=1-5 delims= " %%a in ('netstat -on ^|find ":1099"') do (
set PID=%%e
taskkill /f /PID !PID!
)
