Windows Vista: EDatabaseError: [DBNETLIB][ConnectionWrite (send()).] General network error. Check your network docu...

Hello,

I have a SBS Server 2003 R2 / SQL Server 2005 with 10 Windows XP Pro SP2 Clients and since two weeks 2 Windows Vista Business Clients.

My application is written in Delphi 7 using dbExpress and dbxsda.dll 3.10.7.0.

On the Windows Vista Clients I get from time to time the following error:
EDatabaseError: [DBNETLIB][ConnectionWrite (send()).] General network error. Check your network documentation...

The original german error message: EDatabaseError: [DBNETLIB][ConnectionWrite (send()).] Allgemeiner Netzwerkfehler. Weitere Informationen finden Sie in der Dokumentation...

The application is running for 1 or 2 hours without problems, then suddenly the error occurs. I've never had this error on any of the Windows XP Clients. I installed Windows XP on the Windows Vista computers on a separate HDD partition and started my application. It still runs without any errors until now.

So I think it has something to do with Windows Vista. Maybe the new MDAC version has a problem.

Does anyone have the same problems?

Regards

It is unlikely that the problem concerns the MDAC version.
Possibly your firewall causes such behaviour.
Disable the firewall and try again.

We do have the same problem here. At this moment we have 9 customers working with a SBS Server 2003 R2 / SQL Server 2005 Express with some Windows XP Pro SP2 Clients and some Windows Vista Business Clients.

Only on the Windows Vista Clients we get from time to time the following error:
EDatabaseError: [DBNETLIB][ConnectionWrite (send()).] General network error. Check your network documentation...

Our application is written in Delphi 7 using dbExpress.

@Dimon: We have the same problem and the two links did not help to solve it.

This problem is connected with working of SQL Server and not with DbxSda.
To solve the problem check if Windows Authentication solves the problem. For this you should clear the User_Name parameter.
Also try to use the SQL Native Client provider.

We already switched to SQL Native Client provider but no improvement.

Will try your suggestion with Windows Authentication.

Thanks
