There are three methods that you can use: Right click on the Local InterBase Server icon and select "Startup Configuration" then select "Manual Startup". Try taking the Local InterBase Server out of you Startup Menu, or comment it from the run/load lines of your Win.ini file. Run REGEDIT.EXE and activate the key: HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Run and remove manually the IBSERVER entry.
