Windows Server DNS Cache

[RobBentley]

Hello,

Does anybody know how to stop / shorted the DNS cache in Windows Server 2003. If we change an IP address of one of our webservers (etc) the only way to see the change for the best part of 24hours is restart the Windows 2003 DNS server service or right click it in MMC and click "Clear Cache".

The DNS server is using root hints to resolve WAN queries.

It may take upto 4 hours to change the DNS setting on the internet and this is due to the root hints DNS settings

If you trying to conect localy (within your Domain) try changing the cashe setting in DNS

By default the TTL (time to live) is set 1 hour, you can change this for the whole zone or just a single device in the properties in DNS, However the problem could also be to do with the Replication of Active directory if you have Active directory intergated DNS.

In this case if you can leave the TTL to 1 hour which will leave the cashe setting the same and try forcing replication.

you can also flush the DNS cashe on the client PC by typing at the command prompt IPCONFIG /flushdns
