I have two machines, and I am trying to copy files from one to the other via SCP.
Since this machine is accessible from two of our networks, we're trying to restrict the use of SCP to a select few individuals to prevent unauthorized data transmission from network to network.
What we did was we chmodded 700 /usr/bin/scp. The owner has remained root and the group has remianed root.
From a different machine, I'm trying to scp to that machine, but I'm receiving an "access denied".
My ssh key is in the authorized users file in the root profile.
Anyone have a logical explanation?

So your setup is while setting at host1 you execute scp root@host3:myfile root@host2: and get "access denied"?
further I expect you are using ssh-agent.
if so, I expect it has something to do with scp dropping agent forwarding. search 'scp agent forwarding' I once found a script to work around it, but that is painful.

there are many ways for users to circumvent this, e.g. cat <file> | ssh otherhost "cat > file" or using their own scp binary (copied from a different machine, or extracted from the .rpm)
