Windows Server 2012-based cluster responds to requests slowly

Applies to: Windows Server 2012 DatacenterWindows Server 2012 DatacenterWindows Server 2012 Standard

When a client computer calls the Getaddrinfo function to access a Windows Server 2012-based cluster to perform name-to-address transactions, there is a delay of two to three seconds for the accessing. Additionally, the DNS cache is cleared every 60 seconds if the client computer is a Windows Server Failover Clustering (WSFC) node. Therefore, the delay frequently occurs.


Microsoft has confirmed that this is a problem in the Microsoft products that are listed in the "Applies to" section.
