Outpost

just wondering, can u get the SAM files ?
if u can get it, get some tools to brute it

ps if u dont like retina, get nmap

instead of trying to guess ur way in, get a vulnerability scanner (*cough* Retina *cough*) and scan for other vulnerabilities that the server may have, you might just stike lucky if they dont update their boxes often

cheers and g'luck
