Hello, Balla;
the first thing to check is that the ASP.NET Worker process has rights to your Temp folder. You will find where it is by checking your Environment variables.
Use the correct name for the ASP.NET worker process depending on your operating system - LocalMachine\IIS_WPG(Windows 2003 Server) or ASPNET(XP) or (Vista) IIS_IUSRS
To give the IIS_WPG account full control of a folder:
1. Right-click the folder and select 'Properties'.
2. Go to the 'Security' tab and click the 'Add' button.
3. Click the 'Locations' button and select the
computer name. Click 'OK'.
4. Type "IIS_WPG" under the 'Enter the object names to
select' box.
5. Click 'Check Names'. <Your machine name>\IIS_WPG
appears. Click 'OK'.
6. Check 'Full Control' from 'Permissions for IIS_WPG'.
Click 'OK'.
====================
NOTE:
The IIS_WPG includes the LocalService,
System, and NetworkService accounts.
====================
If that is not the issue:
What database driver are you using in the design of your report? Go to Database|Set datasource location and tell me the properties of the database connection.
Do you logon to the database in your code or pass the data to it using Datasets?
Are there subreports in the design? How many are there? What section are they in? What data source does each one use?
Do you have a lot of formulas in the report?
