What is dnsrslvr.dll?
The caching resolver reduces DNS network traffic and speeds name resolution by providing a local cache for DNS queries.
About dnsrslvr.dll (from Microsoft)
“Name query responses are cached for the TTL specified in the response (not to exceed the value specified in the MaxCacheEntryTtlLimit registry entry (HKLM\SYSTEM\CurrentControlSet\Services\Dnscache\Parameters)), and future queries are answered from cache when possible. DNS Resolver Cache Service supports negative caching. For example, if a query is made to a DNS for a particular host name and the response is negative, succeeding queries for the same name will be answered (negatively) from the cache for an amount of time equal to the value in the NegativeCacheTime registry entry (HKLMSYSTEMCurrentControlSetServicesDnscacheParameters) (the default value is 300 seconds).”
