I was told my DNS server allows Zone transfers and was asked if this could be disabled. The zone in question is a primary DNS zone. From what I've read in the forums I believe a primary DNS Zone will only do out bound (push) transfers and not allow in bound transfers. Is this correct? I do have the Zone Out Filter configured for those servers that should receive updates from my DNS server. Is this all I need to do to secure my DNS server? I'm running NetWare 6.5 SP5. Thanks
