I think the main answer you're looking for is that success and failure of a command can be tracked by the automatic variable %ERRORLEVEL% and choices can be made in the script with "IF ERRORLEVEL":
::::::
net use \\10.40.12.1\ipc$ >NUL 2>NUL
IF ERRORLEVEL 2 GOTO :NEXT
echo \\10.40.12.1 has IPC$ >> c:\temp\ipc.txt
:NEXT
::::::
Note that error level 2 or any error higher would match the IF and bypass. No error (Success=0) or error level 1 (share is there but we cannot connect) would fails the above IF, and causes the reported line.
If you want to expand that to a "walk" you can drop it into a FOR loop:
::::::
FOR /L %%K IN (1,1,254) DO (
net use \\10.40.12.%%K\ipc$ >NUL 2>NUL
IF NOT ERRORLEVEL 2 echo \\10.40.12.1 has IPC$ >> c:\temp\ipc.txt
IF NOT ERRORLEVEL 1 net use \\10.40.12.%%K\ipc$ /delete >NUL 2>NUL
)
::::::
Notice, if it's there we report it even if a level one error prevented using it. We only need to release the resource to clean up our act if it actually did connect.

You could try this:
@echo off
set reportFile=Output.txt
if "%~1"=="REFRESH" if exist "%reportFile%" del "%reportFile%"
set firstTime=Y
for /f "tokens=1,2" %%a in ('net use 2^>NUL' ^| findstr /l /i IPC$') do if not "%%b"=="" call :PROCESS "%%b"
goto :EOF
:PROCESS
if "%firstTime%"=="Y" (
>>%reportFile% echo [%date% %time%] %computername% has IPC$ mapped
set firstTime=
)
>>%reportFile% echo %~1
You'd want to change reportFile to a network share that accessable to all computers. A problem with this might be file contention. In that case you could modify the processing to output to a file that uses the individual's machine name and place the output in some directory on a network share.
This processing allows you to clear the content of the report file by passing REFRESH as a command line parameter.
Good Luck,
