NFS Mount FreeBSD 8.0

[Grant Peel]

   Hi all,

I have been running a backups storage server for many years on FreeBSD 
5.2.1. It has been and still is working fine. Several 6.x machines are 
connected to it on the local network.

Since installing FreeBSD 8.0 on two machines (they used to run 6.x and 
connected to the nfs mount fine), But with FreeBSD 8, the are no longer 
connecting.

ps ax shows (on the client machiens)

  551  ??  Is     0:00.00 mount_nfs -t 10 -b -o rw enterprise:/mnt /mnt

Obviously backgrounded.

It never connects. df- h confirms this.

I have tested the network thuroughly, i.e. I can connect to the backup 
machine using ssh, ftp etc. named is working fine, hosts file is correct.

-No firewalling issues,
-quadruple checked the network settings,
-Checked all the settings for nfs.
-Have added the patches from Errata (all 7 of them).

I was wondering if there is some new/changed settings for the client that I 
missed in the documentation somewhere.

SERVER SETTINGS:

    rc.conf
        nfs_client_enable="YES"
        nfs_server_enable="YES"
        nfs_server_flags="-h 192.168.0.4 -n 15"
        rpcbind_enable="YES"

    /etc/exports
        /mnt -alldirs -mapall root -network 192.168.0.0 -mask 255.255.255.0

CLIENT SETTINGS:

    rc.conf
        nfs_reserved_port_only="YES"
        nfs_client_enable="YES"

    fstab
        enterprise:/mnt         /mnt            nfs     -t=10,-b,rw     0 
0

Any hints would be appreciated.
