I am working with users on both Macs and Windows XP machines and I'm trying to make it easier for them to login to remote databases that require authentication from another server. Right now, when the dialog box pops up for authentication, it autofills the account name either from the windows registry or on a mac, through the FM preferences. I found where to change the automatically filled information on the mac, but I haven't been able to locate where to change it in the registry for windows. Does anyone know the path to the key for this? I don't need to change it with a script for multiple users as most machines are single user machines. Thanks.

You'll need to change it *before* FM launches because it reads that key only once. Easiest way to make sure it's set to the username of whoever is logged into Windows is to use a Windows logon VBscript to change the key.

In FileMaker application select Edit menu >> Preferences. 'Preferences' dialog box pops-up. On 'General' tab, there is 'User Name' option. Change this to required. Next time onwards, whenever you open fp file this username is filled in as default account name in authentication dialog box.
