Acrobat asking for a PRN file two times during the process

Question

Hello all, let me explain this a little more :
- i'm in MS Word (for exemple)
- i want to convert the DOC into a PDF file
- i use the "print --> Adobe PDF" or the "convert to PDF" icone (no matter)
- Acrobat ask me to name the PDF file he will create. I answer
- then he starts to convert
- he stops and ask me to name a PRN file (???). I answer
- he stops again, and ask me to name another PRN file (name must be different from the first one). I answer
- then, he creates the PDF, and the 2 PRN files (???)
The point is, when i have 20 PDF to create, he stops 40 times... i have no idea why he's doing this.
Of course, the box "print to file" is not checked.
the computer is a Windows XP SP3, with Office 2003 and Acrobat 8 pro from the Creative Suite 3 Design Premium.
It is a shared computer. Everything worked fine before, but someone should have done something wrong on the computer... i do not find what.
Anyone can help ? ;o)

This is interesting because it is not the box which Acrobat puts up.
That has a title of "Save PDF file as" and a "Save as type" of "PDF
files".
The box you are seeing is exactly the one you get in Word when
printing to a file (not in other programs). So something is making
Word think it is printing to file - and as long as it thinks that you
won't get a PDF.
It may be worth looking in the Printers Control Panel and checking the
PORT shown for the Adobe PDF printer. The port should be "Adobe PDF".
If the port is set to "FILE", you will see this effect.
