Can't deploy Data Cube from SQL BIDS 2005 - A connection cannot be made. Ensure that the server is running.

Hello,
I am trying to deploy a Data Cube to a named instance on SQL Server 2005, but am getting the error messages below.
SSAS is installed for this instance and the service is running.
SQL Browser is also running.
I can connect and get the Relational DB tables, so my connection string is correct.
My Impersonation Information is using a User name and Password that have domain access.

Here's my error message when I go to the Browser

TITLE: Microsoft Visual Studio
------------------------------

A connection cannot be made. Ensure that the server is running.

ADDITIONAL INFORMATION:

Unable to read data from the transport connection: An existing connection was forcibly closed by the remote host. (System)

An existing connection was forcibly closed by the remote host (System)

Here's the error message when I try to deploy:

Error    1    The project could not be deployed to the '<server>\<namedinstance>' 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.        0    0   


Could someone please assist?

Thank you,
Aaron
