Ah, the details. I always seem to forget that you need to see them.
The server is running Microsoft Small Business Server 2003 Premium edition with ISA Server 2000 SP1.
ISA was installed at the very beginning.
The C:\Program Files\Microsoft ISA Server\avpxyftr.dll file does exist and is version 4.1.357.0 with a date of April 21, 2004.
Thanks,
