SYMPTOMS
When an ASP application is updated on a dual processor server, there is a possibility that the Internet Information Server (IIS) will deadlock and the service will stop servicing requests. The only way to stop IIS is to restart the server.



CAUSE
Two IIS threads are executing on each of the system's processors. Each thread is waiting on the other thread to complete, causing the deadlock.



RESOLUTION
A supported fix that corrects this problem is now available from Microsoft, but has not been fully regression tested and should be applied only to systems experiencing this specific problem. If you are not severely affected by this specific problem, Microsoft recommends that you wait for the next Windows NT service pack.
