Thanks for the replies.  My netork machine is on before I bring up the poser machine.  The mapping works fine in other apps and even Poser can see the files when I click on the add button albeit with a big red X next to each drive.  This only when I first start the poser machine and bring poser up the first time.  The "GPP" issues sounds like it might be what's going on.  What does "GPP" stand for?  I'm not familiar with the acronym.
