IIS8 Asp.net State service remote connection failure
- by maxisam
Recently we upgrade our web server to windows server 2012 with IIS8.
We have this issue when users try to connect the asp.net state service to this web server remotely.
It always popup 
  Unable to make the session state request to the session state server.
  Please ensure that the ASP.NET State service is started and that the
  client and server ports are the same.  If the server is on a remote
  machine, please ensure that it accepts remote requests by checking the
  value of
  HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\aspnet_state\Parameters\AllowRemoteConnection.
  If the server is on the local machine, and if the before mentioned
  registry value does not exist or is set to 0, then the state server
  connection string must use either 'localhost' or '127.0.0.1' as the
  server name.
In IIS7 / 7.5 we use the same way and it works fine. As long as the state service is running and firewall is set properly, we don't have any problem. However, in IIS8 it doesn't work. (We even turn off firewall to test it)
Thanks for helping.
