If I have my web server on a different machine from my Sql Server machine and I'm making calls to it from my asp pages, over which port does the web server talk to Sql Server? I thought it was 1433, but after changing the default port in the Server Network Utility to something other than 1433, my dbase-driven asp pages still work without changing my connection string. Is 1433 only used for Sql Server client connections? Thanks.
