batch file If exist timeout

Question

I tried following code:

if exist "\\%1\c$\users\Public\" (
set sysos=Windows 7
) else (
set sysos=Windows XP
)

But when they can't find \\computername\c$ it takes more than 20 seconds for a time out. How can I create a shorter timeout in the code?

I tried clarifying the question based on what I think you were trying to ask. If I guessed incorrectly then please edit the question to better highlight what you are wanting accomplished. — Matthew Green, Feb 11 '14 at 17:22

See if this solves your issue:

set "sysos="
ping -n 1 %1 >nul && if exist "\\%1\c$\users\Public\" (
      set sysos=Windows 7
   ) else (
      set sysos=Windows XP
   )
if not defined sysos echo %1 server is offline

May be with WMIC commands it will work faster ?

@echo off
setlocal

for /f  delims^= %%a in ('wmic /node:%~1 os get version /format:Wmiclivalueformat') do (
    for /f %%O in ("%%~a") do set "%%O"

)
set /a version=%version:.=%

if %version% LSS 620000 if %version% GEQ 610000(
    set "sysos=Windows 7"
)

if %version% LEQ 520000 if %version% GEQ 510000(
    set "sysos=Windows XP"
)

echo %sysos%
endlocal

Does not check if the remote machine exists...
