NFS - Solaris 10 client from Ubuntu server gives Rpcbind error

Question

Hello All,
New to Solaris, and I've been scouring the Internet to find a solution, but none have been produced. I'll start by giving you details about the setups, and then go into the error:
Server Setup:
Ubuntu 8.04
Exports file ->
/home/<folder> <Solaris 10 Server DNS name>(rw,no_subtree_check,async)
Client Setup:
Solaris 10
Set /etc/default/nfs to have NFS_CLIENT_VERSMAX=3
Ran svcadm -v enable -r network/nfs/client and then tried
mount -F nfs <Ubuntu Server DNS name>:/home/<folder> /mnt/test/
and all I ever get are Rpcbind failure - RPC: Timed Out and then it says it's retrying: /mnt/test
I've gotten the firewall out of the way, I can ping the Ubuntu server from the Solaris server and vice versa, and I'm able to mount the Ubuntu NFS share on another Ubuntu machine perfectly, but I can't get it to mount on the Solaris server. If I specify v3 of NFS, that doesn't change anything. If I specify v4 of NFS, I get the error that the file or folder doesn't exist on the Ubuntu server.
Any ideas? Any more info needed?

This is the exact same problem I've been having. My server is Ubuntu 8.10, and the client is Solaris 10. This is on my home network, so I'm pretty confident it isn't a network issue. I do NFS all the time at work between Solaris machines, but I'm stumped on this one. I've noticed there are similar threads on the topic with no real answer that I have found --

I did a dfshares from the Solaris box, and I actually get a response listing the shares. Even though I can see it I still can't mount it. Here is what I see:
bash-3.00# dfshares tabasco
RESOURCE SERVER ACCESS TRANSPORT
tabasco:/media/Shared tabasco - -
bash-3.00# mount -F nfs -o ro tabasco:/media/Shared /mnt
nfs mount: tabasco:/media/Shared: No such file or directory
bash-3.00#
NFS is working on the server, as I can mount it locally (see below)
root@tabasco:/# cat /etc/exports
/media/Shared *(ro,sync)
root@tabasco:/# mount tabasco:/media/Shared /mnt
root@tabasco:/# cd /mnt
root@tabasco:/mnt# ls
Videos lost+found Music Pictures Other
root@tabasco:/mnt#
Yes... my server''s name is tabasco... remember it's a home network... and I like Tabasco... :)
