A deadlock occurs when a program that uses WMI calls the LoadLibrary() or the FreeLibrary() function in Windows 2000

Article ID: 834010 - View products that this article applies to.

SYMPTOMS

Assume that a Microsoft ASP.NET program or a program that uses a Windows Management Instrumentation (WMI) provider makes direct or indirect calls to the LoadLibrary function or to the FreeLibrary function to load a DLL. Then, the DLL calls the RegisterTraceGuids or the UnRegisterTraceGuids function in the DllMain export function. In this scenario, a deadlock may occur in the ASP.NET program or in the program that uses a WMI provider.

For example, Microsoft Internet Explorer, Control Panel, and the Add/Remove Programs tool may stop responding (hang) after you install Microsoft Windows 2000 Service Pack 3 (SP3) or Service Pack 4 (SP4). When you stop the Remote Registry service, this permits the programs that have stopped responding to resume. This issue may occur in environments where a remote performance monitoring solution, such as PerfMan or SiteScope, is installed.

Also, when this issue occurs, Microsoft Visual Basic scripts may not run correctly, and you receive no error message. Additionally, the Task Scheduler tool may not run.
