Question : reporting services needs to pull data via linked-server

I have SSRS 2005 on Server A. I have data on Server B. A linked server exists on both servers to pull data. The report works just fine in Visual Studio.

After I've deployed the report to SSRS on Server A, I am getting an error that states "An error has occurred during report processing. Cannot create a connection to data source 'VIP_Data' "  

(VIP_Data is a data source that points to the data on Server B.)

I assume this issue has to do with setting security to  Windows Authentication and that my credentials are not being passed to Server B.

What is the work-around?
