Symptoms

After a Windows Vista system or a Windows Server 2008 system runs continuously for 30 to 45 days, the Microsoft Internet Information Services (IIS) 7.0 performance counters stop updating. Therefore, you cannot collect IIS 7.0 performance data by using Reliability and Performance Monitor. Additionally, an application event that resembles the following is logged in Event Viewer:

Cause

This issue occurs because of an optimization logic that was introduced in IIS 7.0. This logic ignores the queued performance counter requests when the time stamps of the queued performance counter requests are smaller than the time stamps of the performance counter data in shared memory.

IIS 7.0 uses the GetTickCount Win32 API to obtain the time stamp values for both the queued performance counter requests and the performance counter data in the shared memory. These time stamp values are stored as DWORD values and are reset to zero if the system runs continuously for 49.7 days.

After the time stamp value of a request is reset to zero, the time stamp value of a request is always smaller than the time stamps in shared memory. Therefore, the request is ignored and the IIS performance counters stop updating.
