On a Windows Server 2003-based computer that has security update 941672 installed, you may experience the following issues:
•
A DNS server consumes increasing amounts of memory over time. In extreme cases, the DNS server may consume about 2.8 gigabytes (GB) of memory on an x86-based domain controller that has 4 GB of RAM installed.
•
A DNS server consumes more CPU resources than expected. In extreme cases, CPU usage for the DNS server may reach 100 percent.
•
DNS stops responding after several days of run time. When you restart the operating system on the DNS server or when you restart DNS, DNS functions as expected until a certain threshold of leaked memory is reached again.
•
Computers that have security update 941672 installed become unresponsive to logon requests at the console. Or, they become unresponsive to administration from the local console or from a remote console.
•
Operations that depend on DNS name resolution fail. Such operations include, but are not limited to, the following operations:
•
Logon requests (CTRL+ALT+DEL) from domain members
•
Active Directory directory service replication

Mail flow
•
DNS zones do not load, or they take longer than expected to load. Additionally, zone transfer may fail between primary and secondary DNS servers.
