Greets. For the past couple of nights, I've been getting these Application Log Errors: <err> Microsoft ISA Server Control failed. The failure occurred during Handling Bandwidth Control Service change notification because the system call IasInitializeRouteCache failed. Use the source location 202.1449.3.0.1200.50 to report the failure. The error code in the Data area of the event properties indicates the cause of the failure. For more information about this event, see ISA Server Help. The error description is: Insufficient system resources exist to complete the requested service. </err> Both times, I get about 80 messages in a 5 minute period, and then the external interface shuts down. You can't log into the box locally (sits forever) and must cycle the box. Upon restart, everything comes back up fine. I have looked up the error message, but can't find any information on it. The box is a PII 333 with 256 meg of RAM. All he does is ISA and RAS. Any ideas?
