Authorization Error in Reporting Services on Windows 2003

Hi,
I have just reinstalled Reporting Services on win 2003 server that was
added to a domain and has been renamed. Two strange things happen:
1) In IE I am prompted for an ID and password with a basic security
prompt.
2) After supplying the credentials I get some of the report manager web
page but it has a 401 error instead of the folder and options to manage
projects.
The page looks like this:
Error
The request failed with HTTP status 401: Unauthorized.
Home
The reporting services error log contains the following error:
Unknown!ui!ed8!2/9/2005-20:44:32:: v VERBOSE: User
map'<Users><User><Name>DOMAIN\Administrator</Name><Paths><Pa=ADth>/reports/= Home.aspx</Path><NrReq>1</NrReq></Paths></User><=AD/Users>'

HTTP status 401: Unauthorized.
Unknown!ui!a24!2/9/2005-20:44:35:: e ERROR: HTTP status code --> 500
I have not changed any of the config files that are installed.
Thanks for any help in advance,
EricTry restarting IIS. I think that is how they fixed the problem here.|||Try restarting IIS. I think that is how they cured the problem here.
