Ok. I'm not so good in long explanations as Helen, but I try.

You use named pipes as connection protocol. This is the source of
your problem, as I told you (or somebody else?) many times before.
Why named pipes are in trouble? Because of this function, called in
fbclient.dll or fbserver.exe: "ImpersonateNamedPipeClient". You can
read what it does in MSDN.
In short: it applies user name, password and rights of user
currently logged in on client computer to server's process. So, this
user must have full access to the database and the password database.
I.e. if you connect to FB server from computer SAMS_COMP where you
are logged in (locally) as SAM, user SAM on server (NSTI-2) must have
read/write access rights on file AUCTIONTRACKER.FDB _and_

You can avoid all these troubles using plain TCP/IP. Just change
connection string to
"NSTI-2:C:\Program Files\AT6TestData\AUCTIONTRACKER.FDB"

This long-standing source of supporing business is removed in FB2.
Thanks to Dmitry Yemanov.
