dns caching on TS portserver 16?

Is there a setting to prevent DNS caching on the terminal servers?

Alternatively, is there a way to get the TS to respect the 0 TTL being passed out in the DNS record?

Or, yet again, is there a command to tell the TS to reset its cache?

I’ve got a bunch of terminal servers, and if the IP address of a machine changes (for now let’s just say this happens relatively often), I’d like new connections to the machine to use the new IP address.

I can update the DNS server, but the TS does not seem to query the server for a particular name after it has recorded it into its cache.


There is a pre-release firmware candidate that has the ability to deactivate DNS caching available from Digi Tech. Support.
