If it helps anyone:
I have a dataportal which is accessed by the public.I have asp pages which have links to report exports(pdf,excel).I access the reports using the URL method.Whenever I click on the Reports it is asking for the username and password(the admin one).I have to avoid this as I cannot make public users enter username and password.how can I do it?
This was my problem
Solution:
Go into the IIS,Go into ReportServer & Reports;Directory Security check anonymous logon and provide admin user name and password.So that the user will not be prompted for user id and password.
