NFS troubles

My 1 year old daughter "rebooted" a machine at home "for" me. Now NFS won't work between two machines.

I have 3 machines; let's call them server, client, and laptop. Each of these machines can mount their own drives over NFS, not useful for too much to me other than NFS debugging. All machines can mount the others drives just fine *EXCEPT* that the laptop can no longer mount drives on the server. The laptop-server NFS connection worked just fine before the server reboot. When I try to mount a server drive on the laptop it just hangs. Looking invar-log-syslog on the laptop I see this:

Port mapper failure - RPC: Unable to receive Mar 20 18:48:15 laptop automount25212: lookup(program): lookup for server failed Mar 20 18:48:15 laptop automount25212: failed to mountnet-server

I don't see anything in the server logs caused by the mount attempt. dmesg on the server says this though:

nfsd: bad address count in freeclient!

That seems to be from the time it booted.

Myetc-exports file on the server says this:

home 192.168.1.2(rw,norootsquash,sync) home 192.168.1.3(rw,norootsquash,sync) home 192.168.1.4(rw,norootsquash,sync)

Myetc-hosts.allow file on the server says this:

ALL: 192.168.1.2 ALL: 192.168.1.3 ALL: 192.168.1.4

I don't think those files would be the source of the trouble since I didn't change them; the machine just rebooted. I don't see any difference in how the server is configured to respond to the client versus how it's configured to respond to the laptop.

The server is Mandrake 9.0 running a 2.4 kernel. The client and laptop are both Mandrake 10.1 running a 2.6.8 kernel.

Anyone know how I can further debug my problem and get the laptop to mount the server via NFS again?

Thanks...
