The information in this article applies to:

- Microsoft Internet Information Server 4.0 
- Microsoft Windows NT Server version 4.0, Terminal Server Edition

SYMPTOMS
========

When you access Performance Monitor counters from the HTTP service or FTP
service from an ActiveX component, the application may stop responding or there
is no data filled out in the Performance Monitor data blocks (the data after the
Performance Monitor header is all zeros).

CAUSE
=====

The FTP service and HTTP service performance object extension fails to serve
Performance Monitor counter data when an OLE Automation Server (out of process)
calls RegQueryValueEx(HKEY_PERFORMANCE_DATA).

RESOLUTION
==========

To resolve this problem, obtain the latest service pack for Windows NT 4.0 or
Windows NT Server 4.0, Terminal Server Edition. For additional information,
please see the following article in the Microsoft Knowledge Base:

version 4.0. This problem was first corrected in Windows NT 4.0 Service Pack 4.0
and Windows NT Server 4.0, Terminal Server Edition Service Pack 4.
