Direct Push has detected that the configuration value for the heartbeat alert threshold is set to a value that is too high. Therefore, the default heartbeat alert threshold of "%1" seconds will be used until the next time that the computer is restarted. To avoid seeing this message in the future, use Internet Information Services (IIS) Manager to correct this configuration. Reset the value to the default, or use another acceptable value.
