How-To: Configure SQL TCP stack

Product: All

Version & Build: All 





At times Modus WebAdmin would fail to authenticate due to a connection or TCP stack error with the SQL server. The SQL TCP stack needs to reflect the information of the local server network configuration.  





Here are the steps to ensure the SQL TCP stack is configured correctly:

     1- For Windows server 2008R2 and lower, Open configuration manager under START - PROGRAMS - MICROSOFT SQL SERVER 20xx - CONFIGURATION TOOLS - SQL SERVER CONFIGURATION MANAGER.

  •  For Windows server 2012R2 and higher, On the desktop Right-Click on the start button and select SEARCH, in the search field type "SQL SERVER CONFIGURATION MANAGER"
  • Then from the list Right-Click on your select and choose "Run as Administrator on the list.

     2- In the SQL Configuration Manager expand the following SQL Server Network Configuration menu and Right-Click on TCP/IP and select properties.

     3- In the TCP/IP Properties page select the IP addresses tab and ensure that all the IP addresses listed represent the same local IP addresses of the server and ensure all interfaces are Active and Enabled.

     4- Once that is done restart SQL express agent so that the changes will take effect.
