    Hi thaiphu007,

    I think there are some errors in your IIS, I suggest that you could reinstall IIS.

    On the other hand, this issue is related to IIS, I suggest that you should post it to the IIS forum for better solution.

    Best Regards

    The symptoms you are facing usually occurs whenever there is an unhandled exception thrown in other than ASP.NET request thread. Do you have any fire&forget threads started by your application? Focus your diagnostics there...

    (In worst case you will have to connect a debugger to your application and wait for the exception, i.e. using AD Plus or DebugDiag.)
