Hello, On the same server (OS 2008 R2), I have SQL Server 2008 R2 + SharePoint 2010 Foundation. I have been able to integrate RS with my SharePoint farm and I am able to publish some reports without any issue. However I noticed in SharePoint IIS logfiles HTTP 401 errors each time a report is displayed : 2010-11-25 09:22:30 #IP# POST /_vti_bin/ReportServer/Reserved.ReportServer - 80 MYDOMAIN\MYLOGIN #IP#- 200 0 0 205 2010-11-25 09:22:30 #IP# POST /Reports/_vti_bin/ReportServer/ReportService2010.asmx - 80 - #IP#- 401 2 5 7 2010-11-25 09:22:30 #IP# POST /Reports/_vti_bin/ReportServer/ReportService2010.asmx - 80 - #IP#- 401 1 2148074254 7 2010-11-25 09:22:30 #IP# POST /_vti_bin/ReportServer/Reserved.ReportServer - 80 MYDOMAIN\MYLOGIN #IP#- 200 0 0 118 2010-11-25 09:22:30 #IP# POST /Reports/_vti_bin/ReportServer/ReportService2010.asmx - 80 - #IP#- 401 2 5 4 2010-11-25 09:22:30 #IP# POST /Reports/_vti_bin/ReportServer/ReportService2010.asmx - 80 - #IP#- 401 1 2148074254 5 2010-11-25 09:22:30 #IP# POST /_vti_bin/ReportServer/Reserved.ReportServer - 80 MYDOMAIN\MYLOGIN #IP#- 200 0 0 220 2010-11-25 09:22:30 #IP# POST /Reports/_vti_bin/ReportServer/ReportService2010.asmx - 80 - #IP#- 401 2 5 6 2010-11-25 09:22:30 #IP# POST /Reports/_vti_bin/ReportServer/ReportService2010.asmx - 80 - #IP#- 401 1 2148074254 6 2010-11-25 09:22:30 #IP# POST /_vti_bin/ReportServer/Reserved.ReportServer - 80 MYDOMAIN\MYLOGIN #IP#- 200 0 0 155 2010-11-25 09:22:30 #IP# POST /Reports/_vti_bin/ReportServer/ReportService2010.asmx - 80 - #IP#- 401 2 5 3 2010-11-25 09:22:30 #IP# POST /Reports/_vti_bin/ReportServer/ReportService2010.asmx - 80 - #IP#- 401 1 2148074254 6 2010-11-25 09:22:32 #IP# POST /_vti_bin/ReportServer/Reserved.ReportServer - 80 MYDOMAIN\MYLOGIN #IP#- 200 0 0 1081 2010-11-25 09:22:32 #IP# POST /Reports/_vti_bin/ReportServer/ReportService2010.asmx - 80 - #IP#- 401 2 5 4 2010-11-25 09:22:32 #IP# POST /Reports/_vti_bin/ReportServer/ReportService2010.asmx - 80 - #IP#- 401 1 2148074254 3 2010-11-25 09:22:32 #IP# POST /_vti_bin/ReportServer/Reserved.ReportServer - 80 MYDOMAIN\MYLOGIN #IP#- 200 0 0 192 Any idea ?

Hi Sylvain, The "Reports/_vti_bin/ReportServer/ReportService2010.asmx ....... 401 1" log error message indicates that some account try to access reporting services web services but failed. And your reports do not call any RS webserivces methods, so they works. I would suggest you logon the IIS manager and make sure the IIS authentication uses Windows Integrated Authentication who should can access web services (ReportServices2010.asmx) instead of Anoymous accout. thanks, Jerry

Hello Jerry, Basically I have not changed default settings regarding authentication methods. It is already set to Windows integrated only as configured during SharePoint setup. The above log is definitely related to the same access. This is the test server that was only accessed by myself. HTTP 401 are generated at the time I want to access any report. Each time I want to access a report: 1. Those HTTP 401 access are generated 2. Access is granted with Windows authentication Regards.
