I can ping machines across our WAN successfully. However, ping -R
(record route) to the same hosts fail. Any suggestions?

Thanks,

Jason

A router has been configured to drop any IP packet with unusual IP options
set? This is often done in the name of 'security', even if it makes no
difference to the security of the system.

You could see if you can get your system administrator to install 'traceroute'.
This takes a different approach, in that it constructs packets that are
designed to fail, and then prints the resulting errors. Note that traceroute
is much more disruptive to the network than 'ping -R' so you should ask your
network people to fix the 'ping -R' problem if possible, rather than use
traceroute.
