AD Migration

My facility’s network is a Novell/Windows environment. Authentication is Novell and fileshare is as well. While we’re running 5.1, we have a W2k SQL server we’re beginning to use DNS services on and would like to eliminiate the Novell authentication, with the exception of the fileshare. For SOX compliance our corporate has developed a batch file for synchronizing which is breaking down but will not be supported.

So, my question is, is it safe to use a server running SQL as DNS & authentication? DNS was running on this machine for quite some time before my arrival on-scene but not utilized.

Your help appreciated.
