Hello. Here's my situation. server A has files I need on server C, but server A is in a PCI zone, so I can't directly connect server C to server A. Ok, I'll share the files from server A to server B, then access server B from server C. I tried this using nfs, but found out that this was a nfs re-export issue that isn't really kosher. So I tried exporting via cifs from server A to server B, but I'm unable to do so. I'm getting error 13 permission denied going from server B to server A. It should be noted that server B is currently serving a share for server A. Sorry about the confusion.

from server B:
sudo mount -t cifs -vvv //serverA/835 /mnt/835 -o username=user,password=******
