Two things there: first, it looks like there might be some firewall working and blocking the rpcinfo connections; second, I think there are usually other services shown in rpcinfo on nfs servers, like lockd and mountd or similar. I'm not sure how RedHat starts such things, but debian has /etc/init.d/nfs-common start /etc/init.d/nfs-user-server start or similar.
Just noticed one more:
[root@dell stelmack]# more /etc/exports 192.168.1.2(rw) 192.168.1.1(rw)
That doesn't look like a valid exports file to me. Check it against man 5 exports on your system (which might use a different format).
Hope that helps,
