Hey guys,
So we want to set a registry entry on our Windows 7 machines to get avoid negative lookups to be cached on the local computer. I found that the registry entry that takes care of this isMaxNegativeCacheTtl to be set under HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\DNSCache\Parameters
So I have been testing this out on a number of machines and it tools like this registry value has a minimum threshold of 60 seconds. So even if I give it a value of 0 or 5 seconds, the negative cache still takes 60 seconds to clear out. Is there a way to get rid of the negative cache right away?
Thanks.
Bilal
