Nfs client mount RPC Error: Program not registered.


I was having few issues on my linux box, I am getting this error whenever I tried to mount a share on a client linux host.

# mount -t nfs /mnt
mount: mount to NFS server '' failed: RPC Error: Program not registered.

I see the error and I tried to restart portmap but that did not helpful. Running into same issue.
I see the rpc.statd process running and rpc.lockd process not running, how can I start rpc.lockd service

While I was going through couple of online links, mentioned "If you are using a 2.2 or later kernel with the /proc filesystem you can check the latter by reading the file /proc/filesystems and making sure there is a line containing nfs. If not, typing insmod nfs may make it magically appear if NFS has been compiled as a module; otherwise, you will need to build (or download) a kernel that has NFS support built in." -- I did checked in /proc/filesystems I didnot see nfsd entry. So in this case do I need to start nfs serivce on the client, to load nfsd module??

not sure what am I missing here to fix this issue.

I was able to mount the nfs filesystem.
but this is what I noticed, first time when I tired to mount it using fqdn of nfs server, I got this error message.
mount: mount to NFS server '' failed: RPC Error: Program not registered.

Then when I tried to remount with IP address it worked fine.

Not sure why I am getting this error, but when I run nslookup on or nfs I got the response, but not sure why mount command is not picking up from DNS. What am I missing any idea ??
