I have Firebird 1.5.4 running on a Vista machine. I'm calling gbak
from a C++ Builder program. Initial error message was "system can't
find fbclient.dll". I located this file in the Firbird folder and
copied it to the System32 folder. On next call, I get the error
message "unavailable database". I verified the Firebird server was
running as a Service. Any ideas what might cause this error?

Thanks,
Warren S.
