Connect to Firebird 1.5 database on Windows Vista using Local Protocol

Using Local Protocol to connect to Firebird database no longer works in Windows Vista when we install firebird server using setup file's default configuration. Using local connection is convenient and fast if we perform GBAK, GFIX, QLI operation compare to TCP/IP connection. To configure Firebird 1.5 works with windows vista for local connection, install the firebird server to run as application instead of service: I haven't try using local connection for Firebird 2.x install on windows vista. Some suggest that changing IPCName in firebird.conf works even running firebird as service.
