Performance Monitor Counters Produce Unlikely Results

• Microsoft Windows NT Server versions 3.5, 3.51

SYMPTOMS

When you use the HALAPIC.DLL hardware abstraction layer (HAL), applications that query performance counters may produce unlikely results. For example, Network Monitor Agent counters may produce numbers for network use that are known to be incorrect.

CAUSE

Applications that query Performance Counters on Intel based symmetric multi- processing (SMP) computers may receive incorrect timer information. As a result, counter values in Performance Monitor, and other programs that are calculated against this timer, may be incorrect.

RESOLUTION

To correct this problem, upgrade to Windows NT 3.51 (if you have not already done so) and install the latest U.S. Service Pack for Windows NT version 3.51.

STATUS

Microsoft has confirmed this to be a problem in Windows NT versions 3.5 and 3.51. This problem has been corrected in the latest U.S. Service Pack for Windows NT version 3.51.
