Link problem between PCs and Macs

Question

Hello.  We have 3 Macs running OSX 10.5.x and Adobe Std CS5, and they share their Illustrator creations, images, etc., on a NAS file server.  Recently, I downloaded the CS5.5. trial version for a PC running Windows XP Pro and on the same network with same file access and security.  All machines use CIFS to access files.
PC user will create an Illustrator file in one of these shared folders on the NAS and link in images from another shared folder on the NAS and save it.  When a Mac user opens the Illustrator file, however, none of the links are valid so the Mac user has to re-link those images and re-save the file.  What change(s) do I need to make on the PC-side to stop this problem?  Does the PC need to be on CS5, too?

Thanks to both of you for your help.  We found out that the PC and Mac show the absolute path slightly differently when connecting to our NAS. However, if we create an ai file with linked images on the PC, save it, and then open it in the Mac, even though the links are off we can fix all of them if we simply re-link one image and then "Ignore" the rest of the pop-up error messages.  There are less (or no) link issues if the images are in the same folder as the ai file, but that kind of defeats the advantage of linking over embedding.  We need to have one central images folder since the same image can be used many times over.  Is there any way to force Illustrator to use relative paths instead of absolut paths?  For example,  if I have a share name "Sales" and three folder within:  "Images", "ABC company" and "DEF company", can the ai files I create in ABC company contain links like, "..\Images\image01.eps" instead of something like \\NAS2\Sales\Images\image01.eps?   Would be nice if Adobe Illustrator had a preference setting of something like "Default location of ai files" where I can set it to, \\NAS2\Sales\, and then any documents I create would use that setting as a link starting point.
