|
|
|
|
<P>When ADO communicates with a database it does so through a networking library. Your selection of a networking library will be determined by the data provider and system configuration, and can have a significant impact on database access speed. For example, if you are accessing data from a Microsoft SQL Server database your access speed, in general, will be faster if you use the TCP/IP networking library. However, if SQL Server is running on the same computer as IIS, you may find some performance improvements by using the Named Pipes networking library.</P>
|
|
|
|
<P>You can set the networking library for a DSN by using the <B>Data Sources (ODBC)</B> option in Control Panel. Once you set a library for one connection, it will become the default library for all subsequent connections, as well as for any DSN-less connections that your application may use.</P>
|
|
|
|
<P><span class=le><B>Note </B></span>If you change the network library from Named Pipes to TCP/IP, be sure not to remove Named Pipes as one of the options, because SQL Server Enterprise Manager relies on this library.</P>
