title: Flamerobin doesn't connect to Firebird database (msg: -902 isc_attach_database failed)
body: <p>I'm studying Firebird 2.5 with FlameRobin 0.9, installed on a VM Virtualbox (with O.S. Win7 32bit PRO). The .fdb files are on the same disk of the Firebird machine and the FlameRobin program. The machine is not embedded and run as Superserver.</p>
  
  <p>With FlameRobin I've created more than one.FDB file, created tables, triggers, generators, etc: all works fine.</p>
  
  <p>I use Delphi7 to create executables that utilize the .fdb file.
  Yesterday, during a proof, Delphi arise an error of "out of system resource": disconnect .FDB in Flamerobin, close Flamerobin (quit), close the VM; re-open the VM, re-open FlameRobin, re-register the .fdb... error: </p>
  
  <blockquote>
    <p>IBPP:: SQLException; Context: Database::Connect; Message: SC_ATTACH_DATABASE
    failed; SQL message: -902 unsuccessful execution caused by a system error
    that precludes successful execution of subsequent statements. Unable to 
    complete network request to host LocalHost.</p>
  </blockquote>
  
  <p>On the VM there is no antivirus and Windows firewall is disabled (on the host machine, Avast Internet Security is running).</p>
  
  <ul>
  <li>I've haven't varied any parameters, all is developed as described. </li>
  <li>In the .conf file, the Firebird machine can connect to all.</li>
  <li>If I use a program compiled with Delphi, to insert or update some record in a Firebird table, all works fine, but FlameRobin doesn't want connect to Fdb.</li>
  <li>In FlameRobin, the item "user manager" lists SYSDBA-masterkey and another user added by me 10 days ago.</li>
  </ul>
  
  <p>On Internet, I've not found cases of the kind. Does it depend on Win7? And how? Can someone help me, to continue the work? Thanks for any suggestion that can be useful to understand the problem.</p>
