I've wrote a handy batch file that painlessly generates the WOL.dat file for you. I borrowed a big chunk of the code from Rob van der Woude of www.robvanderwoude.com

Right now the process writes to c:\WOL.dat, just change that to where you would like the dat file to be stored. This process checks for the computer name in WOL.dat, and removes it's line from the file if it is found. This makes it easy to update a computer's mac address in event of name change or a new NIC. It also pings for the computer before it does makes any changes to the dat file. If the computer isn't found, nothing is changed. Anyways.. have fun with it, hope it helps some of you.

Just make a .bat file with this as its contents, and make a new Hyena tool that calls newBatFile.bat %e%

edit: added some checks for when nbstat does not find a mac address..

edit: Added a nslookup check to confirm the computer name and IP correspond with each other. I also made the log only have one entry per computer, to help keep track of which computers need to be updated. Also added checks to work better when updating the same computer the script is running from.

Hopefully there will be no more updates..
