Can't display reports from Eclipse client

We have a project which will not display reports from the Eclipse
client. It works from the web client, but not Eclipse. The server is
running RTC 2.0.

Multiple users report the problem. The same Eclipse client can run
reports from other repositories, and even another project in the same
repository.

Running a shared report usually results in this error displayed in the
editor pane instead of the report:

This program cannot display the webpage
Most likely causes:
- you are not connected to the internet
- the website is encountering problems
- there might be a typing error in the address

I've also seen this error:

Navigation to the webpage was canceled
What you can try:
- Refresh the page

I don't see anything pertaining to this in the system log. The project
public URI root appears to be configured correctly.

Thanks for your help.

Can you confirm you're running on Windows? If so, what version of
Internet Explorer do you have installed? Any interesting differences in
the configurations of the different servers that might help?

If you could open a work item against the Reports component with the
details, we can use this to track the problem.

Thanks,
