"Stop error code 0x00000048" occurs when you stop the Computer Browser service

This article was previously published under Q331484
Under a race condition, you may receive a "Stop 0x00000048" error message when you stop the Computer Browser service.
This problem occurs in the Kernel-mode browser code. The code processes all canceled I/O request packets (IRPs) on a particular queue, instead of only the IRP that was passed to it. The code does this without holding the cancel spinlock, so other IRPs might be in the process of being canceled while the code is running.
