Intermittent 401: Not Authorized

The first time I try to access a RS report after an IISreset, I get a
"System.Net.WebException: The request failed with HTTP status 401:
Unauthorized." error. If I try to access it again, I get in without a
problem.
In addition to the "first attempt after the iisreset", which happens
consistently, we also intermittently experience the same error, infrequently.
Any idea what is going on here? Caching of Credentials?
Michael DorfmanHello Michael,
To understand the issue better, I'd like to know the following information:
1. Does the issue only occur with a specific RS report or any RS report
such as sample reports including in RS installation?
2. Do you have anonymous access enabled on Report Manager or Report Server
virtual directories?
Also, this issue might be related to a known issue in .Net framework 1.1
sp1, I suggest that you contact CSS to get 887563 installed hotfix 887563
to see if it helps:
884537 FIX: You may receive a "System.Net.WebException" error message when
you
http://support.microsoft.com/?id=884537
887563 Availability of the .NET Framework 1.1 Post-Service Pack 1 rollup
http://support.microsoft.com/?id=887563
Also, please search if there are multiple copies of security.dll on your
SQL Reporting Services machine. If there are security.dll other than
%windir%\system32 folder, please tempoarily rename them to test the
situation.

||||Are you using 2003 server and applied SP1? If so, I did the following and
solved my same problem:
"create a DWORD entry called DisableLoopbackCheck to
HKLM\System\CurrentControlSet\Control\Lsa. Set this key to a value of 1"
This is an issue which occures after appling SP1 to 2003 server.
I hope, this helps.
