For a client, there are usually 2 places to look for nfs mounts defns:

1. /etc/fstab
2. autofs: start with /etc/auto.master, which may refer to other files http://www.linuxtopia.org/online_boo...ig-autofs.html.

If you're really unlucky you may have to look at NIS or LDAP maps. See that doc.

Can you post the contents of
Code:
/sbin/ifconfig -a
Code:
more /etc/fstab
and
Code:
more /etc/mtab
from the server and two client computers of a given cloned lab?

Does everything work correctly on the original lab that you made the clones from?

After you made changes to the different network files, did you restart the network services?
Code:
service network restart
(or if you have restarted the system, it would accomplish the same thing).

mount.nfs: backgrounding "192.168.20.51:home/atcsys/atc_storage/exports/exported/mounts/"

mount.nfs: mount options: "bg,vers=4,addr=192.168.20.51,clientaddr=192.168.20.46"

The computer I did this on is the correct client address of ....46 but it is calling on the original .51, rather than the new server IP ....44. How do I change what this mount.nfs is trying to call on so that it will auto-mount to 192.168.20.44?
I understand that I am quoting myself but after everyones previous advice still hadn't solved anything I went looking for that "/home/atcsys/atc_storage/exports/exported/mounts/" directory and couldn't find it. I then looked around and found this directory instead:

/home/atcsys/atc_storage/shared/mounts

What I found in there is a directory named 192.168.20.51!

Well, now I just need to figure out how to replace that folder and make a folder with 192.168.20.44 in there and it actually call on that folder. I guess I need to work on trying to edit that mount.nfs.

I did restart the computers after changing it all. It seems that the command more /etc/fstab does show it is calling on .51

If I changed the fstab, that should work correct?


[EDIT]

I tried that, and it is still not working, I will do the same results for that and if they're different then I paste it.

You would have to change /etc/fstab, then unmount the current mount to .51, then run
Code:
 mount -a
