I have installed SQL Server 2008 R2 in with Analysis Services. My PC has Windows XP with User "abcd" as administrator role. I have created "abcd" as sql login as well and gave all the availiable permission. I have given all the persions for that user through regedit as well. Yet i receive error, Unable to connect to server 'localhost'. Please make sure user 'HO-IT-01\abcd' has at least read permission to some database on the server. I tried to change the localhost and change with the instance name as well. Looking forward for positive response. Please help.
