Unable to process the objects in Analysis Services but deploy

This ate few minutes from my allocated time :). I was able to successfully deploy the Analysis Services 2008 project to another server that has only SSAS 2008 installed but had no way of processing. I was able to connect to the SSAS via MS too and see the deployed items but it did not allow me to process too. This was the error; OLE DB error: OLE DB or ODBC error: Login timeout expired; HYT00; A network-related or instance-specific error has occurred while establishing a connection to SQL Server. Server is not found or not accessible. Check if instance name is correct and if SQL Server is configured to allow remote connections. For more information see SQL Server Books Online.; 08001; Named Pipes Provider: Could not open a connection to SQL Server [2]. ; 08001. I was bit confused but finally figured out the problem. The issue was with the data source. Though the connection string that was used with data source in the project can be used for connecting to the data source, once deployed, SSAS cannot connect to the data source via same credential. I changed the credential of project's the data source that allows to connect to the data source from both machine. Finally I was able to deploy and process the objects :). You may face for same, hence shared it.
