go to the dos promt and type cd\
and then edit fixblast.bat.
That will becaome your batch file.
edit assume that you out the fixblast.exe also in the root directory of the pc, the line in the batch file would be c:\fixblast.exe
and save it.
put that fixblast in the startup folder of all users so it will run as soon as someone loggs into the pc.
Another way of doing it is to put the file fixblast.exe in the netlogon folder of the w2k advance so that it will run also as soon as somebody logs in. (less work, but would only run for nt based systems not w9x systems)
