Perfmon and Network Monitor Counters Show Incorrect Values (137968)

This article was previously published under Q137968 SYMPTOMS
Under heavy stress situations, Windows NT computers running Network Monitor
or Performance Monitor on a Token Ring 16Mb network with a NetFlx Eth/TR II
network interface card (NIC) return zero for the following performance
counters:
Perfmon Network Segment Object:
% Broadcast frames
% Multicast Frames
% Network utilization
Broadcast frames received/second
Multicast frames received/second
Total bytes received/second
Network General
% Broadcast frames
% Multicast Frames
% Network utilization
Broadcast frames received/second
Multicast frames received/second
Total bytes received/second
This typically occurs when network utilization is continuously greater than
70-80 percent.
NOTE: The Performance counters do appear after a short period of time to
recover as the values start to again increment but they never fully recover
in that the values appear extremely low.
CAUSE
The NetFlex II NIC stops responding (hangs) and the counters are reset to 0.
RESOLUTION
This problem has been corrected in the latest Service Pack for Windows NT
version 3.51. Windows NT now polls the NIC every 2 seconds to check for a
hung condition. If hung, it is reset, but not into promiscuous mode. This
problem does not happen when the NIC is running in normal mode.
STATUS
Microsoft has confirmed this to be a problem in Windows NT version 3.51.
This problem was corrected in the latest Windows NT 3.51 U.S. Service Pack.
