Subject Re: [firebird-support] Cannot open database file in local hard disk

Hello Eduardo,

you might want to check the setting DatabaseAccess in firebird.conf. If it is set to None or Restrict for some reason the behaviour you describe can happen.

Best regards,

I use Firebird 2.1 and in some computers I cannot open a database file which is in the local hard disk.

For example, let's suppose I have the database C:\Test\MYDATABASE.FDB and I try to open it with IB_SQL (from IBObjects).

If I use C:\Test\MYDATABASE.FDB I get "unavailable database".
If I use SERVERNAME:C:\Test\MYDATABASE.FDB I get "unavailable database".
If I use \\SERVERNAME\C:\Test\MYDATABASE.FDB I get "unavailable database".

If I modify firebird.conf creating the alias MYDATABASE=C:\Test\MYDATABASE.FDB, then using MYDATABASE I can open the database.

In almost every computer with any Windows version (XP, 7, 10, 2003, 2008, 2012, 2016) I can open the database using every one of the four methods, but in some computers the first three methods return "unavailable database" and I can open the database only using an alias. Now I am having the problem in a computer with Windows Server 2008 R2 Standard with Service Pack 1, but I remember having this problem in other computers from time to time.

Any ideas of which may be the reason? ... and the solution?

Thanks in advance. Regards
