Hay list, First thing I want to sorta do a network security lockdown... so, here is what I want to do. I want to set up a dns server on my linux box, and have windows signing into it. I also want to have 128 bit authentication (which ever one the dns server and windows both support) Last, I want to set up an acl for some of the users on this windows system. Can someone help me with what programs to use? Thanks,
