,Xresources and ,Xdefaults ignored.

Below are my two files (.Xdefaults and .Xresources); when I open an xterm window, I get the desired results on two of my linux servers, but I get no effect on my third linux servers. It is as if these two files are not being read. Any ideas?

.Xdefaults:
!after editing .Xdefaults it may be reloaded with:
!xrdb -load ~/.Xdefaults
