PDC, MS Word

[Steve Lee]

I have setup Samba default from 
RedHat 7.2. ver 2.2.1a as a PDC
for my windows =network.  I all works
great except when i try to use
MS Word, i get this error

"word cannot complete the save due to a file permission error"

does anyone know how to remedy this problem.
permissio for the my profile is okay, i am able to
write when i log out, only when i try to use
MS word, this error pops up.
