DNS SOA standards for internal DNS
Please show me what good (standard), settings (i.e. Refresh #, Retry #, Expire #, Minimun #, and TTL for this record #'s), should be for an internal Server 2003 DNS SOA Record (not much changes as far as adding new fqdn's are concerned).
Also, what does "TTL for this record (DDDD:HH::MM::SS)", stand for?
Thank you!!

here is a good web definition of dns TTL
http://www.menandmice.com/online_docs_and_faq/glossary/glossarytoc.htm?ttl.htm
also from from sybex's MCSE 70-216 study guide: "the elapsed time in seconds that a DNS server is allowed to cache any resource records from this database file. This is the value that is sent out with all query responses from this zone file when the individual resource refore doesn't contain an overriding value."
as noted in my first post, the min TTL RFC standard is 1-3 hours

What I meant by "what does "TTL for this record (DDDD:HH::MM::SS)", stand for?", was "what does it do?" Also, " what should I set it to?"
