The SQL 2005 HTTP endpoint had been successfully created using the code and the SQL stored Procedures for the custom database had successfully been created . The connection to the HTTP URL from a remote machine was successful but when the same URL was tried from the MOSS server itself it gave a 501 error. Trying to connect to the ?WSDL link as a webservice from the SI Configurator also was unsuccessful resulting in not being able to see the Stored Procedures form the SI webparts

The Endpoint was dropped and then created again after making the following changes on the line
AS HTTP (PATH=N'/TestOffer', PORTS = (CLEAR), AUTHENTICATION = (NTLM, KERBEROS, INTEGRATED), SITE=N'TestServer', CLEAR_PORT = 80, COMPRESSION=DISABLED)
AS HTTP (PATH=N'/TestOffer', PORTS = (CLEAR), AUTHENTICATION = (NTLM), SITE=N'TestServer', CLEAR_PORT = 80, COMPRESSION=DISABLED)
Mentioning all the three methods (NTLM, KERBEROS, INTEGRATED) for authentication was failing the connection of the SI webpart as a WebService and hence not being able to expose the Stored Procedures in SQL
Modifying it to show only '(NTLM)' resolved the issue.
