I have RS2k on SQL2k for several months with no issues, all users can access
reports for which they have been granted access.

I have one new user lately that has not been able to access a report that he
has been granted access to.

He clicks the link to the report server http://servername.domain.com/reports 
and gets directed to the Home folder where he can see the report folder he
needs.

Then he clicks the folder icon so that he is at .../HisRptFolder/ and sees
the two linked reports that his user group has been granted access to. When
he clicks the hyperlink to either of these two reports, the header fo the
site (that has the breadcrumb bar) is still viewable, but the part of the
page that would normally show the "report is generating" message does not
appear and instead he gets a 'Page Not Found' error.

I have tried granting access to his username specifically, but no success.
I have looked at the web.config file but did not make any changes
(Impersonate is set to true, but no username or password is specified which
should cause the logged on user credentials to pass through.)
No other users are having this issue.
The reports are linked to reports in another folder which he does not have
access to.

Any suggestions?

Thanks.
