I am new bie trying to learn SSAS. I have these errors in trying to process my cube after it has shown to have deployed successfully. I need help.

2. Errors in the high-level relational engine. A connection could not be made to the Data source with the Data source ID of 'AdventureWorksDW2008R2', Name of 'AdventureWorksDW2008R2'.
3. Errors in the OLAP storage engine: An error occured while the dimension with the ID of 'Dim Date', Name of 'Dim Date' was being processed.
4.Errors in the OLAP storage engine: An error occured while the 'Date key' attribute of the 'Dim Date' dimension from the 'SSAS Project' database was being processed.
5. Internal error: The operation terminated unsuccessfully.
6. Server: The operation has been cancelled.

it seems that the SQL server that has your relational database has 'NT AUTHORITY\NETWORK SERVICE' rights wrong.
Go to your SQL server, expand security and then expand Logins, find 'NT AUTHORITY\NETWORK SERVICE', double click. See what roles it has, probably only public checked. Mark everything else. Since you set up 'NT AUTHORITY\NETWORK SERVICE' to be a default service account, you can give it more rights that public.

I have the same problem. I have SQL 2008 installed on my local system. Created a windows local account and in SQL server added this account with sysadmin access. I have changed the account in the analysis servesis services(configuration manager) to this account. Now I am able to start and stop services but when I go nad try to process any dimension in SSAS I get the above error.
OLE DB error: OLE DB or ODBC error: Login failed for user '029W-8MS0CK1\srini'.; 28000.
Process failed.
Any suggestions appriciated Thanks for reading.

| I solved the problem by going to impersonation tab of my data source and providing my windows login username and password.

I am hi-jacking this thread. I have a similar problem as srivasuk described: I have a Windows global admin account under which all SQL Processen run. I receive the same cannot-login-failure, made this account explicitly member of the Windows Administrators group. Did not work, gave it explicitly SA role within SQL Server, still I receive this cannot-login-error.
Now, I can try one of the solutions given, but I would like to understand what is happening here. Also, it is policy here to use this specific global account for these services. In another, similar, SSAS setup this account gives no problem. Obviously there must be a difference, but I cannot find what that is.
Any other hints?
TIA
EDIT/SOLUTION: I found out that the datasources of the cubes where pointing to an alias, which is used on all servers of a specific OTAP que. This new server did not yet have this alias installed, hence the login failure. I am amazed however why I get this cannot-login-error, and not a cannot-find-server/alias...

This error is caused by the Data Source connection not having access into the OTLP database. Connect to your SSAS instance and verify the connection string of your data source is accurate. Make sure to update the Security Settings to use the proper Impersonation Info. The impersonation info defines what credentials to use to connect to the data source, independent of who triggers the processing.
Most likely, your Analysis Services is running under 'NT AUTHORITY\NETWORK SERVICE' and your impersonation settings is set to Run As Service Account. In production environments I've worked in, we usually create a windows service account that runs Analysis Services and grant that service account read access to the underlying data sources. In dev environments, I just run the service under my credentials or just set the data source to use my credentials by using Impersonate Account.

Thanks - yulia.klimov, your answer below is still helping people. It solved my problem running the basic tutorial using AdventureWorksDW2008R2_Data.mdf
yulia.klimov (12/20/2010) it seems that the SQL server that has your relational database has 'NT AUTHORITY\NETWORK SERVICE' rights wrong.
Go to your SQL server, expand security and then expand Logins, find 'NT AUTHORITY\NETWORK SERVICE', double click. See what roles it has, probably only public checked. Mark everything else.
