        A flaw in the ISA Server DNS intrusion detection filter could result in a denial of service. If you have configured your ISA Server computer to server publish DNS, the DNS intrusion detection filter may not properly handle a specific type of request. In this case, ISA Server would stop sending further DNS requests to the DNS server. All other ISA Server functionality would not be affected. For more information, see Knowledge Base Article 331065. This security patch resolves the issue.
