I've got some problems with using fully qualified domain names (FQDN) while getting to Portal.
Having EP installed and running properly, I've installed, on my MS Windows 2003 Server (on which my EP is running), DNS to provide FQDN.
Until this my EP worked properly (I get to my portal main page using host name without FQDN - http://<host>:<port>/irj).
After installing DNS and configuring new domain my EP runs properly when I get via simple hostname, but I've noticed, that it isn't working properly, when I try to get via url with FQDN.
The FQDN is correctly recognized on sysop level (ping...) - the problem is surely in EP configuration.
The most common symptom is an empty HTTP page or a portal page containing some interface elements, but without content.
Who knows what I have to change in my EP configuration?
I will be thanful for any help.
