Originally IPv6 was disabled before starting the install and that djava line was already part of the registry (they must have fixed it in the latest install package).

In the end it turned out that from the server you cannot load the FQDN url, but using IP or just netbios works just fine.

Beats the hell out of me WHY its doing that, but I am ok living with that result. I just edited the URL shortcut file to be netbios name...
