Viewing Reports Via Report Manager Fails (while Other Methods Succeed)

I'm having a strange problem with SSRS 2005 that I'm hoping someone might be able to help with. I've reinstalled SSRS (multiple times) and even reinstalled IIS hoping to resolve the problem, but it still exists.

The problem is that trying to view a report via Report Manager is failing. All other operations within Report Manager work fine (browsing folders and report lists, viewing folder and report properties, changing properties, setting permissions, etc.) Only trying to view reports fails. Whenever I try to view a report, I get the following error:

The request failed with HTTP status 401: Access Denied.


I can view reports via other methods just fine. For example, if I browse to the http://localhost/reportserver URL directly, I can view any report just fine. And if I connect to SSRS via SSMS, I can view reports there as well. I believe that both of those methods use a direct reportserver URL versus using the http://localhost/Reports/Pages/Report.aspx page within the Report Manager virtual directory.

Here's a bit of configuration information that may or may not be helpful to someone:

1. This is on a laptop running Windows XP SP2 (32-bit). SSRS (and all SQL Server components) are installed as default instances and SQL Server SP2 has been applied to everything.

2. All of the latest updates and fixes for Windows, SQL Server, Office, etc. have been installed via Windows Update.

3. This laptop is a member of a domain, but I am typically not connected to the domain (not in the office very often). I am, however, logging into the laptop using a domain account (with cached credentials). Local user accounts are frowned on by the domain and IT administrators involved (except for running local services). My domain account has full admin permissions within Windows and within SQL everywhere.

4. As far as I can tell, everything with regards to IIS, asp.net, and SSRS are configured correctly (ASPNET account seems to be set up correctly, all SQL services including the SSRS service are running under a local account with admin permissions, the Reports and ReportServer virtual directories in IIS are set to use Integrated Security, etc.)

I'm not an expert on SSRS, so this one has me stumped. I've reviewed all of the config files that I can think of looking at for SSRS and I've looked at the SSRS logs. Nothing really jumps out at me in terms of changes that might be required (and the SSRS logs don't really say much other than repeating the error). For example, I see the following lines in the ReportServerWebApp__xxx.log file:

aspnet_wp!ui!8!5/14/2008-13:00:17:: e ERROR: The request failed with HTTP status 401: Access Denied.
aspnet_wp!ui!8!5/14/2008-13:00:17:: e ERROR: HTTP status code --> 500
-------Details--------
System.Net.WebException: The request failed with HTTP status 401: Access Denied.

Anyone have any ideas? I've searched Google for quite a while trying to find something that would help me figure this out, but thus far I've not been able to come up with anything. Any help (or pointers to something on teh web somewhere that I might have missed) would be appreciated!!
