SQL Server 2005 Connection Error

I have a application written in classic ASP that I am having problems getting to connect to a SQL Server 2005 server. This application has been running for years on SQL Sever 2000, but the server the database is on is being taken down and replaced with on on 2005. The following is what I am using to connect (which works fine on the old 2000 server).

Code:

set objConn = Server.CreateObject("adodb.connection") 	 		
ds = "MYSERVER
pwd = "PASSWORD"
user = "USER"
db = "DATABASE"
connstr = "Provider=SQLOLEDB.1;Password=" & pwd & ";Persist Security Info=True;User ID=" & user & ";Initial Catalog=" & db & ";Data Source=" & ds
objConn.Open connstr

When I use this I get the following error.

Using the same user name and password I am able to log into the new server with Query Analyzer so I know that isn't the problem. I am also able to create a ODBC connection with this user and password. Any ideas?
