Method One:

Open the Web. config file under the site directory, navigate to the configuration section,

<sessionState mode="StateServer"

   stateConnectionString="tcpip=127.0.0.1:10001"

   cookieless="false" timeout="60" />

The mode= "StateServer" is modified to Mode= "InProc".

Method Two:

Do not modify the mode= "StateServer" and modify the Stateconnectionstring= "tcpip=127.0.0.1:10001".

Navigate to Registry Hkey_local_machine\system\currentcontrolset\services\aspnet_state\parameters\

Modify the port configured for stateconnectionstring= "tcpip=127.0.0.1:10001" to a registry key port (42424) port number, as follows:

Stateconnectionstring= "tcpip=127.0.0.1:42424"
