Denise,

I am totally guessing here, but I ran across this little snippet of
information in some of David Bartosik's documentation:

"An issue that was found during testing of this feature is that on some web
servers the sites supporting folder (containing all pages after the home
page) is hidden, not visible when logged on to the server and viewing the
contents. MS identified this as being an issue with the web servers handling
of xml files. The user can contact their web host about this permissions
issue or they can elect to not use the supporting folder option."

While there is really nothing you can do to change the coding engine in Pub
2003, but perhaps go to Web Site Options > untick the "Organize supporting
files in folder" option, along with "enable incremental...", "Rely on
VML...", and "Allow PNG...", and see if that helps at all.
