Perflib Error in NT

I am getting the following error and am not sure what it can be attributed to:  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.

The error shows up in the Event Viewer, and it seems to refer to NWLink.  NWLink IPX/SPX is disabled on this system.  The system is running IIS4, Cold Fusion, and connecting via NetBUEI to a SQL Server for the DB stuff.  Can someone tell me what is causing the error and how to fix it?

If you are using NT 3.51 with SP4, this is a known problem.  It has been corrected in the later SPs.  The reason being, if you have installed NWLink on your computer before, some service is trying to access the IPX/SPX parameters.  Since you disable it now, the service is not getting what it wants. Hence the PERFLIB failure.  
Solution is to find the service and change its settings not to look for IPX/SPX.  
OR
Go to Devices in Control Panel and enable all three NWLink objects.
OR
Upgrade to the latest SP or go to NT 4.0 if it applies.
OR
Do nothing 'cuz it has no effect on the OS performance.  Just consider it a warning if it is not coming in your way.

Good luck..

I am running NT4 with SP3.  Any possibility that these issues could still apply?

Guess so.  Why don't you enable the NWLINK devices for a quick fix?  Later on, you can figure out which application is causing the unwanted errors.  The problem with NT 3.51 I referred to was dealing with the Performance Monitor.  When it tries to get the metrics for IPX/SPX protocol, it fails.  You problem might be associated with some other application.
There is no easy way to point to it, because no one knows (of us) what is running on your PC.  You are best judge.
