I've got two Redhat5/CentOS systems which share a folder. I'm trying to change the shared folder location, but I ran into this error on the machine on which the folder is mounted...

How can I correct this? I rebooted the computer but to no avail.

Server1 - where its "mounted"

/etc/fstab
IPADDRESS2:/opt/programA/common/files    /srv/server2-share nfs rw,intr    0 0

Server2 - where its "shared"

/etc/exports
/opt/programA/common/files IPADDRESS1/28(rw,insecure,sync,no_root_squash)

Ran the following on Server2

root@server2 [~]# /etc/init.d/nfs start
root@server2 [~]# rpcinfo -p
