I have just upgraded my server from CentOS 5 to CentOS 6 and am having connectivity problems. My laptop runs Fedora 14, and I have been in the habit of mounting data partitions on my server by fstab entries. Since the update I've not been able to do that. On watching the messages during a reboot I saw a statement that the connection was denied by the server (where are those messages stored so that I can quote accurately?).
I have temporarily disabled both the firewall and selinux, and the problem persists, so clearly they are not the cause. Logwatch has the following section which may or may not be connected:

An example fstab line is
/Data1 /nfs4exports/Data1 none bind 0 0
Under CentOS 5 this was mounted by the exports line:
/nfs4exports/Data1 192.168.0.0/24(rw,insecure,no_subtree_check,nohide)
Following advice, I have changed this to:
/Data1/ 192.168.0.0/255.255.255.0 *(rw,sync,insecure,no_all_squash)
That hasn't helped at all.
I'm completely at a loss, and really need to get this connection working again. I've done lots of googling and reading, but just feel to be digging an ever-deeper hole. All help appreciated.

I didn't read your original post carefully enough the first time.
You show the exports file, but nowhere do I see a reference of how the client is mounting the export from the server. THe bind mounts above are remounting a local file system in a different location, they do not mount an NFS share from an external server. Usually it looks something like this:
server:/share /local/mount nfs defaults 0 0
(obviously defaults can instead be specific options)
