document.write --- access is denied

I want to write to a frame using document.write but get an 'access is denied' error. The target frame was generated via ASP; I do not get an error if I write to a non-ASP frame. Is there another way to change the content of this ASP frame from a script or is it simply not possible to make the changes because the ASP originates from the server?
Thanks,

Let me guess. Does the file in the other frame reside on the other server? If so that's violation of the same-origin policy (http://www.mozilla.org/projects/security/components/same-origin.html) and as such will throw a security exception.

bingo. thanks for the help and reference. problem solved.
