Integrated Security with local SQL & IIS

I have SQL RS running on a Win 2K (dev only) machine with IIS on the same local machine. I am trying to access the reports from another computer, but am getting an error An error has occurred during report processing. (rsProcessingAborted) Get Online Help Cannot create a connection to data source '<Shared Data Source Name>'. (rsErrorOpeningConnection) Get Online Help Login failed for user '<DOMAINNAME>\Guest'.

IIS and the Datasource are setup for integrated security and the Datasource is aimed at the local SQL DB. Anonymous access is turned off in IIS and it prompts for the login info when trying to access it via the web. My understanding is that this should work without problems due to IIS & SQL being on the same machine, but I can't seem to get it to work. Is there a doc somewhere or anything that goes thru the settings so I can see what I'm missing? Or does anyone have any ideas?

Thanks.

Does it work if you access the reports locally? How about using stored windows credentials for hte data source instead of integrated security?|||

Yes, the reports work fine locally. I just can't access them from another machine. I need to use integrated security due to needing the windows login to lookup the correct info in the report and to know the type of user (admin, basic, etc).

Thanks for your help.

Probably a kerberos configuration issue. Try forcing NTLM. See the workaround in http://support.microsoft.com/default.aspx?scid=kb;en-us;871179
