Thanks and very nice input. And good idea http://www.ipdetective.ca sounds good since lok like new kid on town and only works with windows platform i doubt rs could make software like that
On the large firm network structure,the network itself is composed of many different platform, It depends whether windows,netBSD or Unix which machine is configured as a DNS Server or the FTP server.And for the security issue as you mentioned http://www.ipdetective.ca clould only work for windows.
Recently security is the main issue wherever you name,on wireless,ftp,web server and almost everywhere.
i would recommend www.ipdetective.ca Their software package is intalled on each of your client's computers and it automatically updates their IP address on your ftp site.
Lol,sounds very interesting.
