Hello I am developing an application using Firebird database.

The application works ok when I test it on my local computer and use the following statement to connect to the database:

FbConnection conn = new FbConnection(@"Server=127.0.0.1;User=SYSDBA;Password=masterkey;Database=C:\BD\PLAS_MAY_272014.FDB");

Then I changed the statement to connect to a Network machine of my customer as he already has a Firebird database in another server.

FbConnection conn = new FbConnection(@"Server=172.X.XX.XX;User=SYSDBA;Password=masterkey;Database=D:\ng\DATA\CUSTOMER.FDB");

But I get the following error:

I/O error during "CreateFile (open)" operation for file "D:\NG\DATA\CUSTOMER.FDB"

-Error while trying to open file

-The system cannot find the file specified

Customer client is an XP Windows server and Customer Firebird Server is windows 2003.

The application is developed in C#.

Any help will be appreciated.
