#define EVENT_DNS_CACHE_NETWORK_PERF_WARNING 0x80002B2AL
MessageId: EVENT_DNS_CACHE_NETWORK_PERF_WARNING MessageText: The DNS Client service could not contact any DNS servers for a repeated number of attempts. For the next %3 seconds the DNS Client service will not use the network to avoid further network performance problems. It will resume its normal behavior after that. If this problem persists, verify your TCP/IP configuration, specifically check that you have a preferred (and possibly an alternate) DNS server configured. If the problem continues, verify network conditions to these DNS servers or contact your network administrator.
