Cannot Connect To MSDE 2000

I am trying to connect to a MSDE 2000 database located on a server on my network. I can connect to a SQL Server 2000 database; however, I cannot connect to this MSDE database.

This is the error I get: Code:

Microsoft OLE DB Provider for ODBC Drivers error '80004005'

[Microsoft][ODBC SQL Server Driver][DBNETLIB]SQL Server does not exist or access denied.

/attach2.asp, line 28

Here is my connection string: Code:

<%
Set conn2 = Server.CreateObject("ADODB.Connection")
conn2.Open "Driver={SQL Server};" & _
"Server=192.168.56.181;" & _
"Database=Attachments721;" & _
"Uid=attach12usr;" & _
"Pwd=***;"
%>

What am I doing wrong? I can't figure it out. The ASP page and the MSDE are on two different servers, if that makes any difference. I can add the MSDE server to Enterprise Manger using the same login information too.
