I am still not sold on a single system running CM... If all of your "name resolution"is through this one box, what happens when it dies... and believe me.. it will die at the most inopportune time. NFS mounted filesystems have the same inherent flaw - SPOF (Although I am doing some investigations of the SAN solutions which is making things really interesting in configuring a data center.. and some of these use NFS) That is usually why you have more than one DNS server and usually on different segments. Avoid SPOF (single point of failure) Which is also why I like to use an OpenVMS Cluster, with mirrored disk-subsystems...

Although, since my customers mostly use the U*** word, I am stuck working with it as well.
