SYMPTOMS
Under a race condition, you may receive a &quot;Stop 0x00000048&quot; error message when you stop the Computer Browser service.



CAUSE
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.



RESOLUTION
A supported hotfix is now available from Microsoft, but it is only intended to correct the problem that is described in this article. Only apply it to systems that are experiencing this specific problem. This hotfix may receive additional testing. Therefore, if you are not severely affected by this problem, we recommend that you wait for the next Windows 2000 service pack that contains this hotfix.

To resolve this problem immediately, contact Microsoft Product Support Services to obtain the hotfix. For a complete list of Microsoft Product Support Services telephone numbers and information about support costs, visit the following Microsoft Web site:

Note In special cases, charges that are ordinarily incurred for support calls may be canceled if a Microsoft Support Professional determines that a specific update will resolve your problem. The usual support costs will apply to additional support questions and issues that do not qualify for the specific update in question.
