I´ve a Firebird 2.1 install, multiple databases, users and programs.
In only one workstation (among ~15) and for a single table (from around
100) I got "unavailable database 08004". Always, but not at program
start (I can use the whole program except for that single function). At
all other workstations the program works fine.

Any tip to what should I check? (I´ve verified fbclient and odbcfb
versions, and do an ODBC trace which logs the error at the end of the
trace, plus a few lines like "SQLFreeConnect" and similar).

Thanks!
