Host name couldnu00B4t be resolved

Hi @ all

I Installed SAP NW PI 7.1 with EHP as Standalone system and local. The problem ist i couldn´t access to ESB and Integration Builder. Because only the host name ist displyed and not the FQDN.

I have also maintain all the important parameter like icm/host_name_full and in the etchosts.

I ask if are parameter in Exchange Profil to be also modified'? And how kann i resolve my problem.

Thks a lot
