Please Help me,

We had a Software application Developed using VB6 with MSSQL SERVER2005 as Database(Remote) in www.znetindia.com our web space provider , the application was working properly until they upgraded the Server configuration, Now we are not able to connect with the database using the normal OLEDB connection String

adoConn.Open PROVIDER=MSDataShape;Data Provider=SQLOLEDB.1;Persist Security Info=0;User ID=UserName;Password=Password;Initial Catalog=DatabaseName;Data Source=servername

It is giving an ERROR (Error No.-2147467259 at Line No. 0 ([DBNETLIB][ConnectionOpen (Invalid Instance()).]Invalid connection.) in procedure )

We contacted our service providers they informed that they asked us to try with the SQL Server Instance

adoConn.Open PROVIDER=MSDataShape;Data Provider=SQLOLEDB.1;Persist Security Info=0;User ID=UserName;Password=Password;Initial Catalog=DatabaseName;Data Source=servername/instancename

It is giving an ERROR (Error No.-2147467259 at Line No. 0 ([DBNETLIB][ConnectionOpen (Connect()).]SQL Server does not exist or access denied.) in procedure)

Again they informed to use the ip address instead of servername without the named instance and also with the named instance,but the same errors are generating.

WE TRIED WITH SQL NATIVE CLIENT : -

With Instance Name:

adoConn.Open PROVIDER=MSDataShape;Data Provider=SQLNCLI.1;Persist Security Info=0;User ID=UserName;Password=Password;Initial Catalog=DatabaseName;Data Source=servername/Insancename

Error No.-2147467259 at Line No. 0 (Named Pipes Provider: Could not open a connection to SQL Server [53]. ) in procedure Command1_Click of Form Form1

WithOut Instance Name:

adoConn.Open PROVIDER=MSDataShape;Data Provider=SQLNCLI.1;Persist Security Info=0;User ID=UserName;Password=Password;Initial Catalog=DatabaseName;Data Source=servername

IT IS WORKING PROPERLY.

The Web Service Provider came online using Team Viewer worked directly in our machine and tried the connection string
adoConn.Open PROVIDER=MSDataShape;Data Provider=SQLOLEDB.1;Persist Security Info=0;User ID=UserName;Password=Password;Initial Catalog=DatabaseName;Data Source=servername/instancename

using Microsoft Data Link Provider It is not working and generating Errors.

When they tried in their system with the same connection string using Microsoft Data Link Provider it is connecting with the database without any problems. ( We also viewed through Team Viewer their system)

Please help us to solve this connection problem using OLEDB, because when we use SQL NATIVE CLIENT we will not be able to connect using Crystal Reports 10 because CR10 will not support SQL NATIVE CLIENT.
REWRITING THE ENTIRE APPLICATION TO USE SQL NATIVE CLIENT IS VERY DIFFICULT.

Please help us..

With Thanks,
K.Senthil Babu

user port number also
DataSource = ipaddres or servername,port number
DataSource = ServerName or Ipaddress\InstanceName,port number

Default Port number is 1433 or 1434
