Transfer files on network automatically

Ok, All Techs listen up and provide some sound minded input.

Situation: Have a network throughout an entire state, appox 30 branches, 6 of which logon to the domain. Need to send and replace files automatically (i.e. HOSTS file for internet control).

Problem: No known active directory program or any program that can do this…

Hyena is a great Admin tool, no file transfer setup.

UpdateEXPERT is great and almost there, but only updates Microsoft hotfixes and updates…

Anyoneknow of any new programs or sources of information on what is available for this or would this be alot of scripting?

Thanks for your input
