|EP Installation Error|
The trust relationship between this workstation and the primary domain failed.
1.Check the .net Business connector configuration settings. This might be a naive approach and considering one must have already looked up seeing the log, I am suggesting to do the following work arounds.
1) Stop firewall, all its services, delete all unused inbound policies on firewall.
2) Install AOS , debugger and .net connector upto RU3 on the work station. I don’t know why it required AOS but failed without it.May be its with the configuration.
3) .Delete the workstation from domain and add it again – DNS issue.This is a WSS issue.
4) .If database was restored & EP is installed on one server – clear the BC Proxy account from form.
5) Recompile sysDevelopmentProxy class – ensure it compiles without error for .Net connector to work successfully.
6) Check the site bindings from Share Point servers, also from this server.
Install EP & Role center with some luck.
