The environment will give you %COMPUTERNAME% and %USERDNSNAME%, so you could:

if /i %COMPUTERNAME$ == "HostA" exit (or use a goto label if more needs to be done in the batch).

The /i would mean ignore case.

Copy to checkbginfo.bat
-------------
echo off
for /f "tokens=*" %%G in (testcomps.txt) do if %%G == %computername% (call CALLBGINFO.BAT)
-------------

Where testcomps.txt contains a list of computers you want to run BGINFO on.  Make sure you use UPPERCASE characters to define these.

And CALLBGINFO.BAT is another batch file to call BGINFO with the command line parameters - you probably want to display BGInfo immediately instead of waiting for the timeout.

paka thanks mate

echo off
for /f "tokens=*" %%G in (testcomps.txt) do if %%G == %computername%
(call CALLBGINFO.BAT) do have to use the brackets

testcomps.txt  you mean all the computernames should be uppercase in txt file

my bginfo look like this do i have to change anything

@echo on


del "C:\Documents and Settings\guled\Local Settings\Temp\BGinfo.bmp" /F /Q
echo deleted image
pause
goto Bginfoexe

:bgcreate
echo create directory
pause
mkdir C:\WINDOWS\Temp
cacls C:\WINDOWS\Temp /E /G  "Authenticated Users":F
goto Bginfoexe

:Bginfoexe
if NOT exist C:\WINDOWS\Temp goto bgcreate
echo bg create
pause
start C:\bginfo\bgibmp\bginfo.exe C:\bginfo\bgibmp\bginfo.bgi /silent /nolicprompt /timer:0
echo done
pause
EXIT

Add all 100 computernames to the testcomps.txt file (make sure they are in capital letters) and the batch will read though the file and run BGInfo for those that are in the file.  Obviously, there will be a performance penalty if the the list gets too big, but for 100-200 the hit shouldn't be noticeable.

The for /f statement will take care of loading the names, the if %%G will check the names...

You could have a names.txt of to be excluded then you could do something like:

find %COMPUTERNAME% c:\file.txt > NULL
if ERRORLEVEL 1 exit

I believe this will work, but should definitely tested.

Might need quotes around the variable.

find "%COMPUTERNAME%" c:\file.txt > NULL
