Hi @wiliansilva, 2008 R2 and 2012 are supported by 7.2, which may be downloaded from here: https://www.splunk.com/en_us/download/previous-releases/universalforwarder.html For 2003 you have two options, you can request an old version of the UF from Support, or you can try running one of the newer ones. It won't be supported, but it might work (unfortunately I don't have a 2003 VM where I can test). Good luck! Cheers, - Jo.
