Server console quitting

I VNC in to a remote machine to administer their FMS9 machine on OSX 10.5.8.

Clients can use the served databases just fine. The console loads fine. I can choose any of the Configuration settings just fine.

But as soon as I select any sub heading under the Administration heading, I get an error:

Admin Server Connection Error

Unknown error has occurred

And the console quits.

Any recommendations?
