We want to use our ASA 5520 as a Time Server for a number of our servers. I have configured the ASA to update its time from 3 public NTP servers, and it is running correctly as an NTP client. I want to configure the ASA as the authoritative time source for the Windows Server 2008 that is running the PDC Emulator role, but the ASA is not responding to NTP client requests.
I have no previous experience with the ASA, and as a result, my boss has restricted my access to the GUI only; no command line interface access.
Is it possible to configure the ASA to be a time server, and if so, how can it be done using the GUI?
