First, let me apologize for the late response.
In regard to the drive mapping issue, I think that would be the way to go. We have worked with Microsoft on a printing to file problem on mapped drives within Terminal Services. When attempting to print to a file which included printer codes (Not using the ASCII parameter) we received an error that the target file was unavailable. Using the ASCII parameter to printing it would work. (This problem appears in NOTEPAD.EXE, WORDPAD.EXE, etc. It is not a VFP issue). When we removed drive mappings and worked with the actual drive letters (C: and D:) the reports printed to file without error. Microsoft said the problem was in the TS redirector.
Again, I do apologize for not getting back to you sooner,
