Reload DNS

What are the implications of reloading a DNS Zone? I'm missing an entry and want to repopulate. If I reload the DNS zone will it cause issues?

You may easily create that entry in zone then restart it, that restarting process will take 5 to 10 secs and during it DNS cannot resolve queries.

this will both flush the cache and make the dns server unavailable for a few seconds depending on the performance of your host and the size of your zone.

the cache is not an issue on an authoritative-only server since afaik ms's dns will load the whole zone in memory anyway, but it might be if that same server is also a busy resolver/cache.

as a side note, i see little to no reason why changing or adding a dns entry would require a restart. did you try to simply add the entry ?

What DNS server are you using?

Sometimes, when the zone file is updated, people will forget to update the the sequence number, which results in downstream DNS servers not performing a zone transfer.

Does not apply to AD-integrated zones, of course.
