Loadbalancing CMS 6 with TCP
The event replication module is now handled with an initialisation module in CMS 6. Can you check if you have an entry:
<add name="EventSubscriberHostModule" type="EPiServer.EventSubscriberHostModule, EPiServer" />in your web.config (maybe left over after an upgrade)? We encounted this problem when this module was present. If you remove it then it should sort out the problem.

When trying to set up a site with loadbalancing over TCP the following error occurs:
ERROR [19] EPiServer.Global.Global_Error - 1.2.5 Unhandled exception in ASP.NET

I have followed the instructions at these pages:

I have tried both with localhost and with the internal ip on the server but same result.
