I had to use a Windows 7 machine as Firebird server...after updating firewall rules everything is ok, but Firebird seems to ignore the aliases.conf file...I place the fdb file in a shared folder, with full access granted to everyone, and create the alias. I can access the database locally providing the full path, by if I try to use the alias I got this error:

Unsuccessful execution caused by a system error that precludes successful execution of subsequent statements.
I/O error during "CreateFile (open)" operation for file "XFILES".
Error while trying to open file.

any clues ?
