Error Msg 7399, While Trying Run DMX Query From SQL Server

EXEC master.dbo.sp_addlinkedserver

@server = N'DMServer',

@srvproduct=N'Analysis Services 2005',

@provider=N'MSOLAP',

@datasrc=N'SVRRRDB10DEV',

@catalog=N'Adventure Works DW'

GO

select * from openquery (DMserver, 'SELECT DISTINCT [Gender] FROM TM_Cluster')

(I referred to 'Executing predictions from the SQL Server relational engine' article on this web site)


But I am getting following error :

Msg 7399, Level 16, State 1, Line 1
The OLE DB provider "MSOLAP" for linked server "DMserver" reported an error. Access denied.
Msg 7350, Level 16, State 2, Line 1
Cannot get the column information from OLE DB provider "MSOLAP" for linked server "DMserver".



Pl. help.

Thanks,
