I have a VB 6.0 application which has commands to access a SQL Server 2000 database. Ex:
EZCONN.Open "Provider=SQLOLEDB.1;data source=" & GDBSource & ";Initial Catalog=" & GDBName, GDBUserName, GDBPassword
Where i am reading the parameters from INI file. and the server parameters are given correctly. This line returns the following error:

[DBNETLIB][ConnectionOpen (Connect()).]SQL Server does not exist or access denied.

Actually I am updating some CSV files to the database. For that I am calling databaseupdate procedure and the files gets updated one by one in a loop. I am opening the connection before the loop and i am closing it on form_unload event. The code is written in commandbutton_click event and it gets called once in the form_load event and then I am ending the application. The application is a standalone exe that runs at startup. so there is no any possibility of calling the click event twice. However it is giving this error while updating some files not for all the files. some files are getting updated to the database.

Can anyone tell what is the reason for this error and what is the solution?
please reply ASAP

Thanks..

Hi there,

It looks like your connection string is not OK. Check this page for the correct connection string:

AFAICS, your password / username are not in the correct format.

Hi,

thanks for your reply.

yes the connection string was not proper but then how the application is working ok. The application is working fine since last 3 months. Only sometimes it gives the stated error regarding SQL server not available. The application updates some CSV files to the database successfully using the same connection string as I have given in the earlier post and sometimes it does not update the file to the database giving the error of [DBNETLIB] - is this related to network/port settings. Is it giving this error because of network accessibility problem? If connection string is not proper then it should give error for all the files.

Please reply ASAP.

Thanks again.

Hi Mayuri25

i think it is bcoz of network problem. make sure tht ur server is in the same Domain. also configure SQL Server user with Windows user

now i'm using this and i don't have any problem
Set Conn1 = New Connection
Conn1.ConnectionString = "driver={SQL Server};server=Carlos;uid=;pwd=;database=SysDB; Trusted_Connection=Yes;"
Conn1.Open
