Under Internet Security and Acceleration (ISA) Server stress testing that lasts for an extended period of time, or under similar deployment conditions where there is a continuous and high amount of traffic (TCP or UDP) that utilizes the Secure-NAT functionality of ISA Server, the ISA Server computer may appear to stop responding (hang).
