Can you open them on your PC?
Are they DRM protected?
Do they have some special encryption that needs the latest Adobe reader to be able to read them?
All of the above I have encountered in PDF manuals in the past and I expect to see the problems in the future as well. In fact we have developed a set way of dealing with these problems and we now run any new PDF file through the process as a matter of routine.
I don't know what your problem is with trying to copy across a lan - we do it all the time because our PDF documents are stored on a NAS. The only thing that comes to mind is that they might be 'doctored' PDFs that have some payload that will infect windows based machines - we have seen those in the past although we have yet to see one that messes with the network.
If none of the above helps you could PM me a short one and we'll take a look at it and try and determine what the problem is.
