hey, its rami, and i am breaking my head on that, but still cant find a solution: i have windows xp pro, and i want the logon script -thru Group Policy- will run just at once and not after etc logon. how can i do that? EDIT: ==== in search i was found that: if not exist %systemroot%\nameofile.txt ( some commands another command more commands ) > %systemroot%\nameofile.txt which needed to be in the a batch file at logon script at Group Policy. found here. what it means: some commands another command more commands ? EDIT: ==== solved. i was put an example batch test file which include the lines: if not exist %SYSTEMDRIVE%\text.txt ( copy f:\test.txt c:\test.txt ) > %SYSTEMDRIVE%\test.txt which search if the file test.txt is not found on c:\. if its found he does nothing. if its not found it preform a copying command from to the text.txt file from f:\ to c:\
