HELP! 401 Authentication - Nothing Is Working!
Hi all, I've recently installed a fresh copy of SSRS 2008 for the first time (SQL SERVER 2008 EXPRESS SP2). Straight install. No changes. And of course, it doesn't work! I was able to get to my report manager page, but only after removing RSWindowsNegotiate and RSWindowsNTLM from the rsreportserver.config file and changing it all to RSWindowsBasic. I don't know why that worked, but it did. But now I can't authenticate to my web service. I keep getting 401 errors, and nothing seems to work. I am at my wits end here. Here is what I have tried: FYI, I am using Windows XP SP2, and VS 2008. 1) Changed the rsreportserver.config file so that it uses "RSWindowsBasic". 2) I have opened the Computer Management tool, and in the 6 SQL Server groups, I have added "Administrators", "NT AUTHORITY\SYSTEM", "ASPNET", and "NT AUTHORITY\NETWORK SERVICE". 3) My Execution Account in SSRS Config is "[MACHINE]\LocalSystem". 4) The Report Server Service Account is "Local System". 5) On the "Services" dialog, RS is running as "Local System". 6) My RS code is: rs.Credentials = System.Net.CredentialCache.DefaultCredentials; I assumed this means it runs as ASPNET on my development machine from VS 2008. I have read and re-read everything I can find on this site. I can't think of anything else left to do. I keep reading the same suggestions over and over. What haven't I done? Why isn't it working? Please give me something new to try. I just don't understand what is wrong. I've added EVERYTHING I can think of to the group "SQLServerReportServerUser$DNB01$MSRS10_50.SQLEXPRESS" and all the other SQL Server groups. Is there some other group I can create and add to? Thanks, Michael
