DNS - Any way to force a nameserver to update the record of a domain?

I am doing some work with some domain. I'm upgrading them. By utilizing dig I can quiz our nameserver and also I can see that the proper name has actually been upgraded. Nonetheless our workplace dns cache is still revealing the old name. The other day I set the TTL to 10 mins, so I do not need to wait long. Nonetheless exists any kind of means to fool the workplace is dns cache to update? Any kind of stealthy little method I can do to make points less complicated?

UPDATE Let is think I do not have accessibility to the web server, and also can not reactivate it? Exists anything else I can do?

If you are running BIND as a resolver for your workplace - ie. not forwarding to an additional a resolver.

Flush every little thing in the cache:

rndc flush

Flush a details document:

rndc flushname example.com

If you are forwarding after that you go to the grace of the forwarder is cache.

Assuming your DNS server gets on a computer and also not a router etc:

Linux cache flush:

/etc/init.d/nscd restart

Or for distros without nscd

/etc/init.d/named restart

Windows customer cache flush for specific equipments:

ipconfig /flushdns

Windows server cache flush for workplace server (many thanks to ericmayo for the improvement):

  1. Navigate to Administrator Tools
  2. expand the server object
  3. appropriate click cached things
  4. select clear cache

Mac (perhaps?!):

dscacheutil -flushcache

If you have an internet GUI etc for a router, there will certainly be an alternative in there someplace.

Cross platform cache flushing as above
