BO2K

BO2K is the most powerful network administration tool available for the Microsoft environment, bar none.
Built upon the phenomenal success of Back Orifice released in August 98, BO2K puts network administrators solidly back in control. In control of the system, network, registry, passwords, file system, and processes. BO2K is a lot like other other major file-synchronization and remote control packages that are on the market as commercial products. Except that BO2K is smaller, faster, free, and very, very extensible. With the help of the open-source development community, BO2K will grow even more powerful. With new plugins and features being added all the time, BO2K is an obvious choice for the productive network administrator.
