Perflib Application Log Error when Deploying a Site

[Mike]

Hi.

Each time I move an asp.net file (bin, .aspx file, etc) to my production
server the following error appears in the server's event viewer's application
log.
-------------------------------------------------------------
The Open Procedure for service "IAS" in DLL "C:\WINNT\System32\iasperf.dll"
failed. Performance data for this service will not be available. The Status
code returned is the first DWORD in the attached data.

For more information, see Help and Support Center at

-------------------------------------------------------------

After researching this error I have no idea why it is appearing. Does
anyone know why this appears?

Thanks.
