Solaris 10 U8 DHCP

Question

Hi,
I successfully installed S10U8 on my system when connected via ethernet to a broadband router. I then installed some application software which contains a management browser ie. browse to https://myhostname:port/mgr and this all worked my Internet connection to the outside world was also perfect.
However most of the time I will not be connected to the broadband router in this way but will be standalone so when I broke my network connection and rebooted I got
rtls0: link down
failed to configure DHCP
hostname set to myhostname
which I thought reasonable enough - however just before the JDS desktop environment starts I get a message
popup saying
myhostname not recognised gnome may not continue to work properly you may
want to edit your /etc/hosts file <continue> or <try again>
so I <continue> and login then try to do
telnet myhostname ==> fails as unrecognised
telnet 127.0.0.1 ==> works
and https://myhostname:port/mgr ==>fails as myhostname is unrecognised
but https://127.0.0.1:port/mgr ==> also fails something about being rejected
obviously I want to keep my DHCP configuration as it works and I will be using that network connection
but how do I get myhostname to be recognised in the standalone situation Ie. get
telnet myhostname to work
https://myhostname:port/mgr to work
I am new to this so i think the fix should be easy?

Well this managed to get rid of the gnome popup during login
but still cant telnet.
