Ok -- per the requests above here are the files 

First off -- some background --

The server is our file server -- called SRVFS-01 -- a Pentium 4 2.0ghz
box -- running FC2 -- IP 192.168.0.13
The working server is VULCAN - our testbed server -- a dual Pentium 3
400 running FC3 -- IP 192.168.0.22
The non working server is SRVDB-01 - our database server a Pentium 4 2.
ghz running FC2 -- IP 192.168.0.19



The /etc/exports file from SRVFS-01 -- this is the NFS server

/home 192.168.0.0/255.255.255.0(sync,no_root_squash,rw)
/shared 192.168.0.0/255.255.255.0(sync,no_root_squash,rw)
/root 192.168.0.0/255.255.255.0(sync,no_root_squash,rw)

The FSTAB file from VULCAN -- the test bed server that is working

The Entry for /trial is a test mount that I did from the Vulcan server
to make sure that there was not some thing strange in the client, and it
mounts normally


The output from the mount -a command when run on srvdb-01
