NW6.5sp5 with all patches...

When I run NRM: I don't get the images on the web

When I then enter the username/password and login I get a "page cannot be
found error" and the address line in the browser shows:

If I hit the browser back button I do get to the proper NRM display but
again, the images on the left side of the page do not appear - only Xs. All
functions work properly. My other servers don't exhibit this behavior. What
did I do?
