SQL TCP/IP Configuration

posted by Jason Carreiro in Best Practices on Aug 17, 2011


SQL is installed on your server but not all is as it seems. You begin to notice performance related issues and a delay in the transmission of data. This can be the result of having the configuration manager of SQL configured to use invalid IP addresses.

Example: SQL is installed on server 192.168.0.182, however, in the configuration manager the IP addresses listed for the TCP stack show no indication of the server IP but rather a random IP address.

The protocols for each instance of SQL need to represent the server IP address. Failing to do so can hinder performance for SQL and the server. Noticing network I\O errors with your SQL server can be an indication of the problem.
