Question

@echo off
:begin
for /f %%a in (computerlist.txt) do (
  setlocal
  psexec \\%%a -u user -p password -i -d "d:\path\command.exe"
  endlocal
)

when the script is running, when it finds a machine to be unreachable I want it to skip it.

How do i write the script to skip an unreachable computer and continue to the next one in the txt file?

Answer 1

How about a simple test to see whether a machine is pingable?

@echo off
setlocal
:begin
for /f %%a in (computerlist.txt) do (
    ping -n 1 %%a >NUL 2>NUL
    if %errorlevel%==0 (
        psexec \\%%a -u user -p password -i -d "d:\path\command.exe"
    ) else echo Skipping unreachable host %%a
)
endlocal
