IIS EventLog Errors

Question

I keep getting this error in my event viewer on IIS 6. I'm trying to figure out if my error resets my connection (maybe recycles the worker processes?).

The error is:

An attempt was made to load filter 'C:\Program Files\Software Artisans\FileUp
\FileUpIsapi.dll' but it requires the SF_NOTIFY_READ_RAW_DATA filter notification and 
this notification is not supported in Worker Process Isolation Mode.

Answer 1

Looks like your ISAPI filter is not compatible with IIS6 Worker Process Isolation Mode. It sounds like it was written for IIS5.x.

For more information see this Microsoft KB article:
