Hi Peter, a few things to check, from what you say you are familiar with
FB and Delphi:
localhosts is not needed, its part of the setup of dns

Aliases.conf examples
fibrominn=e:\apps\fibrosys\fibrominn\fibrosys.fdb
pjsmouldings=e:\apps\pjsmould\orders.fdb
miracle=e:\apps\miracle\ordproc\miracle.fdb
These are from a similar setup to your's - windows 7 64bit with Fb 2.5.1
32 bit. Could use 64bit but Udfs don't work well.

Can you run the Delphi app on the machine itself

Is IPV4 running or IPV6 - has been/is a problem on some systems

Hope this helps a bit.
