I just deployed a Sophos UTM 120 for a small office environment. An old Windows 2003 server provides the Windows domain (e.g, authentication and file server services) as well as DHCP and DNS services for the office computers. We have strategic plans to replace the Windows server with a newer model before Windows 2003 goes to end of life next summer.
WISDOM OF THE LIST QUESTION
Which will give us better overall performance and reliability:
(a) Continuing to run DHCP and DNS services from our Windows server?
or
(b) Switching those services to the Sophos UTM?
Are there any penalties or caveats? - Things I should be wary of if we switch off DHCP and DNS on the Windows server? Does the Windows server include additional DHCP or DNS capabilities that the client computers use that I may not be aware of?
Are there other advantages of using one over the other that I am missing?
Are there any similar services that I should be migrating to the UTM (or not)?
