NFS sharing problems

[majestic_looser02]

Here's what I'm trying to do:

My brother has about 80 gigs of stuff on one comp. Some of the files on the hd are from a
partition from a previous install and have a different UID or GID than the his acount now.
We are wanting to send all of these files to another linux box cause he is running out of space. On the server side I have this in /etc/exports:

/home/whatever 192.168.1.100(rw)

I am able to mount this and view it but anytime I try to drag or drop any files it says I do not have read or write access although I have included the "(rw)" option.
any ideas would be greatly appreciated.
thanks

as the owner of the directory or as the root run 'chmod 777 /foldername' see if it helps
