Cannot Launch DTA - Failed to open new connection

Installed SQL 2005 STD and installed SP1 for SQL on a Windows 2003 STD server.

I launch DTA and I am logged in with the same windows account which the SQL services use and I get the following message:

===================================

Failed to open a new connection.

===================================

Could not find stored procedure 'msdb..sp_DTA_help_session'. (.Net SqlClient Data Provider)

Any help would be appreciated.

are you using RTM or sp1 version? a MSFT guy told me that there are problems he has heard of with DTA in the RTM build...I would tell you that while I love the product, DTA has not been the most stable of components overall from my expereinces w/it.|||

I am using the SP1 version for SQL 2005, I didn't even check to see if DTA worked before that since it is a brand new server.

I saw a post that stated the user does not have sysadmin rights for SQL and that is what the error message means but I created a Domain Admin account for SQL and that is what I am logged on to the server with.

Thanks,
Pete
