I am not familiar with Solaris, but if it works the same as RHEL, this
should work.
1. Start X server on PC C.
2. Configure Putty to use X11 on "localhost:0".
3. Ssh to Server B.
4. Ssh with Xll forwarding (usually ssh -X) to Server A.
5. Run X Application.
The key is that by using the above method, your X traffic will be wrapped
in your SSH connection which can traverse your firewall. When you export
your display, you are not wrapping your X traffic in an SSH session, and
most likely, it will not be able to traverse the firewall.
