mount: RPC: Program not registered

I'm trying to mount a share from one Mandrake 10 install on another and I keep getting this error. I'm having other issues with the server as well, like if I try to run a df -h my ssh session freezes and if I try to run rpm it freezes as well. I only have about 3GB of free space so I need to mount a share on a bigger server for a backup. I need to reboot the server to see if it'll clear it but before I do I want to back some of the info up in case it dies. I've verified that portmap, nfs, and rpc.mountd are all running. I've tried recycling the nfs services using /etc/init.d/nfs restart. For some reason I just can't get the command to work.

[root@server init.d]# mount -t nfs 10.x.x.101:/ /home/user1/mount
mount: RPC: Program not registered

[root@server init.d]# rpcinfo -p
program vers proto port
100000 2 tcp 111 portmapper
100000 2 udp 111 portmapper
100003 2 udp 2049 nfs
100003 3 udp 2049 nfs
100003 4 udp 2049 nfs
100003 2 tcp 2049 nfs
100003 3 tcp 2049 nfs
100003 4 tcp 2049 nfs
100005 1 udp 869 mountd
100005 1 tcp 872 mountd
100005 2 udp 869 mountd
100005 2 tcp 872 mountd
100005 3 udp 869 mountd
100005 3 tcp 872 mountd

Other drives are mounted and functioning properly. I've mounted to this server in the past. Just to make sure nfs itself wasn't gummed up, I mounted a share from the server to one I was originally trying to mount and it was successful but it doesn't help as I still have to create the backups on the original server then move them off the share. Does anyone have any ideas as to what I can try that I haven't already?

A couple of things I see here, that you may try.
NFS is a bastard, just by the by.....

Firstly, you state that you have other files mounted on this machine. I would unmount them, as it seems though you are mounting / of that box - which presents a sort of weird conundrum - you have / mounted, but then you also have other dirs deeper in the FS mounted elsewhere - it's a lot for RPC to keep tabs on.

Secondly - omit the "-t nfs".
Mount can determine you mean NFS by the presence of the colon.

Lastly - do you have an entry for / in your /etc/exports file on the server? Does exportfs -a exit 0?
I would umount - on the client - all that you have NFS mounted from that server.
On the server, do an exportfs -ua
Then, remove all but / from the /etc/exports file (leave the perms - rw,root=*, etc....)
Rerun exportfs -a
Try again.

If that doesn't work - exportfs -ua
Restart NFS
exportfs -a

Good luck.

Well, I'm getting timeouts trying to unmount my mounts on the client. My exports file only has / listed and then two entries for two separate servers. exportfs -a shows some stats but no error codes; only suggestions on how to shore up some of my shares. The only connections to the box are at / and there are two mounts off server. I'm afraid I'm going to have to reboot it to get some of these freeze-ups to clear. Sheesh; wish me luck. Thanks for your reply.

I got this error message when trying to mount an NFS share. This article

led me to my solution -- I had neglected to change my /etc/hosts.allow information when I changed the subnet of my network after installing a wireless router.
