Normal
When the tvserver and MySQL Server is on the same host it should also be possible to use a named pipe. That is normally specified using "." as hostname but it's does not yet work to enter "." in the dialog specifying connection parameters. Also the mysqld need to be configured to use names pipes. Use MySQL Administrator and go to "Startup Variables" and check "Enable named pipes". There is a comment saying it will only work on "Windows NT+only" - that includes XP.
