I kind of figured from what I read.  I wish I knew the spec for pnm so I
can
read the header and tell what is wrong with this server's setup.  I
assume
I can't copy an old plugin from 3260 versioning dlls?

Henry, maybe you can answer my other post about where dnet and ddnet has
gone also.
I am having to copy those 3260 dlls to my helix for its use.:(
