If you are referring to the Security Reporter server you would run this at the command line
Let me clarify...I see two options:
1. Resolve the un-resolved IP addresses into fully qualified host names.
2. Perform resolution of IP addresses into host names using cache.
DNS Cache Size (drop down selections are 25MB, 50MB, or 100MB)
Does the first option use the local (security reporter) server's DNS settings?
Where is the cache for option 2, and how can it be flushed?
I never received an answer to the second question. Does anyone know the answer?
I have asked our security reporter SME.
Hopefully have a response tomorrow.
There is not a file that the Firewall reporter is writing too.
To flush the cache you would need to restart the security reporter service under services.
