Thanks for this initial help helen.

ib_sql on the windows workstation allows me to connect to each of
the databases on the (i.p. = 192.168.2.10) server. No problems. I
can browse each database. No error messages and nothing is generated
in the firebird log file when I do this

There is repeated message in the firebird log file which I think
occurred during re-installation. This was due to an installation
issue that I corrected...(I downgraded to 1.5.1 SS which is the same
as the version I have in the office server)
asterisk1.local (Server) Wed Oct 4 21:22:10 2006
INET/INET_connect: gethostbyname failed, error code = 1

I'm not getting any firebird log messages now

Could there be a problem with security.fdb?
