Connection problem SQL Data Tools for VS

Question

Hi
Appologies I hace this question in SSIS forum- but think this is a better place to ask.
I downloaded SSDT for VS in order to try some data mining on my developement edition of SS
When I try to use the mining model viewer (setting up source, sourec view and mining structure all worked fine) - it fails and tells me that "OLE DB error: OLE DB or ODBC error: Login failed for user 'XXXXX\DAVID-PC2$'.; 28000.
When settiing up the Impersanation Info- I used "Use the Service Account".
To get past this bit I was advised by Olaf Helper to change to "Use Credentials of current User" but then it also fails as apparently when you set up SSDT the system creates user credentials that differ to my windows authincation in my SSMS- So
the question is how and what do I change in SSDT so that my Windows Authincation becomes the same as "Use the service Account"- or make both talk to each other.
Hope you can help
Thks

Answer 1

What I'm doing is based is SSDT.
It appears to me that SSDT is configured for Analysis Services to be called Localhost
Went into the Analysis service project- and changed target server from localhost to DM_DEV - when I go into Config Manager I can see that SQL Services Analysis Services (DM_DEV) is running- so is SQL Server Brouser.
But when I'm in the project and try to run it I get
The project could not be deployed to the 'DM_DEV' server because of the following connectivity problems :  A connection cannot be made. Ensure that the server is running.  To verify or update the name of the target server, right-click on the project
in Solution Explorer, select Project Properties, click on the Deployment tab, and then enter the name of the server.
Is there maybe some specific way of putting DM_DEV- e.g in barckets use " " etc? what am I missing here!!
Thanks
