    Port 1433

    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.

    From BOL
    "SQL Server 2000 uses UDP port 1434 to establish communications links from applications"

    For more info, have a look at BOL article "Connections to SQL Server Over the Internet" or search BOL for UDP

    Cheers

    Port number matters only if you connect to sql server with tcp/ip netlib, but not for named pipes.
