I am trying to deploy a report to SSRS using BIS. Every time I deploy, I am prompted with a Reporting Services Login. I shouldn't be getting this dialog. But even when I try every logon username/password combination including the domain in the username and excluding it, the logon fails.
My project TargetDataSourceFolder, TargetReportFolder and TargetServerURL are all set up correctly. I have OverwriteDataSources set to false.
