sql server - "could not find stored procedure"

Question

I am maintaining a classic ASP website that has a SQL Server 2005 backend. For a small piece of new functionality I wrote a stored procedure to do an insert. This is the only user stored procedure in the database.

When I attempt to call the stored procedure from code I get the following error:

Microsoft OLE DB Provider for SQL Server error '80040e14' 
Could not find stored procedure 'InsertGroup'. 
/newGroup.asp, line 84 

The DB uses SQL Server authentication. When I connect to the DB server in Visual Studio using the same user/pw as in the connection string the stored procedure is not visible but all tables are.

The user has datareader and datawriter roles and explicit execute permission on the stored procedure.

What am I missing?

UPDATE: My apologies, the server admin misinformed me that it was a 2000 server when it is actually a 2005 server (running on Windows Server 2003 x64).

Answer 1

Walk of shame:

The connection string was pointing at the live database. The error message was completely accurate - the stored procedure was only present in the dev DB. Thanks to all who provided excellent answers, and my apologies for wasting your time.
