While preview the report in the reporting server it will show me the password expired?

Hi Ychinnari,

Reporting Services provides a special account that is used for unattended report processing and for sending connection requests across the network. The account is used in the following ways:

• Send connection requests over the network for reports that use database authentication, or connect to external report data sources that do not require or use authentication.
  


• Retrieve external image files that are used in report. If you want to use an image file and the file cannot be accessed through Anonymous access, you can configure the unattended report processing account and grant the account permission to access the file.

According to the error message, password of unattended execution account has expired. To troubleshoot the problem, please refer to the following steps:

1. Start the Reporting Services Configuration tool and connect to the report server instance you want to configure.
   


2. On the Execution Account page, select Specify an execution account.
   


3. Type the account and password, retype the password, and then click Apply.
   


4. If credentials are passed in the connection string, you need to modify password of the connection string.

For more information about Configuring the Unattended Execution Account, please refer to the following document:

Thanks,
