Cannot connect SQL-Server from one specific machine on corp network. Other machines connect ok.
Got this error message (vb6) when trying to connect:

Run-time error '2147467259 (80004005)':
Invalid connection string attribute.

SQLserver uses non defalt port,windows authentication, connection string verified ok( as it works in other machines.) Firewall configured ok. User has permissions in SQL-Server database.

>driver={sql server};Provider=SQLOLEDB;
this is the problem. the first part says: use ODBC, the second says use OLEDB.

I suggest to remove the driver={sql server}; part...

angell, What do you mean by "use ODBC" ? "Driver(sql server)", how does this tell to use ODBC ?
I was just wondering why does this work in all other machines and this particular one ?

in short: because. it's the syntax.

see this site for the overview of the connection strings for sql server, and you can see the in the ODBC section, it's the Driver={SQL Server}, while in the OleDb section, it says Provider=SqlOleDB
http://www.connectionstrings.com/?carrier=sqlserver
you won't find a connection string mixing the 2.

>I was just wondering why does this work in all other machines and this particular one ?
sometimes, applications are more flexible/tolerant than others. it's like people :)

</Grading Comments>

at what point?
note: you should use the OleDb provider whenever possible, it should be faster, more functionality, more stable ...
