[Firebird-net-provider] Backup and Restore Problem

[Phillip C. <phi...@ba...>]

Hello,
 
I have just completed a program that performs a Backup and Restore on a
Database using the .NET Data Provider. The program worked fine on my own
computer and a few others that I have tested it on but now I am finding
an increasing number of computers where I get the following error when
the program tries to start the backup:
 
No message for code 152 found.
 
FirebirdSql.Data.Firebird
FirebirdSql.Data.Firebird.FbException: No message for code 152 found.
 ---> FirebirdSql.Data.Firebird.Gds.GdsException: Exception of type
FirebirdSql.Data.Firebird.Gds.GdsException was thrown.
   at FirebirdSql.Data.Firebird.Gds.GdsSvcAttachment.Attach()
   at FirebirdSql.Data.Firebird.Services.FbService.Open()
   --- End of inner exception stack trace ---
   at FirebirdSql.Data.Firebird.Services.FbService.Open()
   at FirebirdSql.Data.Firebird.Services.FbService.startTask()
   at FirebirdSql.Data.Firebird.Services.FbBackup.Start()
   at Database_Cleaner.frmCleaner.Backup()
 
I have tried the program on various version of Firebird and made sure
all people are using the most up to date version of the Firebird .NET
Data Provider by distributing this with the program but to no avail.
Still it is 50\50 whether the program is going to work or not. I also
stop and start the service before the program runs to ensure that the
problem is not related to someone else using the database at the time of
performing the backup.
 
Can anyone think of what could be causing this error and why only a few
people get this problem?
 
Thanks in Advance
Phill
