Performance Monitor Error after Installing NT 3.51 SP4 (148749)

This article was previously published under Q148749 SYMPTOMS
After you upgrade to Windows NT 3.51 Service Pack 4 and run Performance
Monitor, the following event is logged in Event Viewer:
Event ID: 1008
Source: Perflib
Description: The Open Procedure for service "NwlnkSpx" in DLL
"perfctrs.dll" failed. Performance data for this service will
not be available. Status code returned is DWORD 0.
CAUSE
When the NWLINK IPX/SPX protocol is installed, an Nwlnkspx.sys key gets
created in the registry, and it has a Performance key under it. When
Performance Monitor loads, it calls the open SPX performance procedure for
Nwlnkspx.sys. The problem is that Nwlnkspx.sys is not started by default
and the error above is logged. Nwlnkspx.sys gets loaded when an SPX-based
application is started or NET START NWLNKSPX is issued from the command
prompt. NWLNKSPX counters do not appear in Performance Monitor until it has
started.
Changes to Service Pack 4 appear to cause this error. They do not adversely
affect the operating system in any way.
WORKAROUND
To monitor NWLINK IPX/SPX statistics in Windows NT 3.51 Service Pack 4,
type the following at a command prompt:
NOTE: This loads the NWLNKSPX.SYS file, which is necessary to monitor the
NWLINK IPX/SPX statistics.
- or -
Go into Control Panel, Devices and set all three of the NWLink devices to
startup automatically. This will prevent the errors from being logged as
the system is first coming up after a reboot.
STATUS
Microsoft has confirmed this to be a problem in Windows NT version 3.51
Service Pack 4. This problem was corrected in the latest Windows NT 3.51
U.S. Service Pack. For information on obtaining the Service Pack, query on
