<p class=MsoNormal><span style='color:#1F497D'><o:p> </o:p></span></p>
<p class=MsoNormal><span style='color:#1F497D'>When connecting to an OMERO
server which is not in the DNS, the name of that server must be entered in the client's
local hosts file (even in Windows).<o:p></o:p></span></p>
<p class=MsoNormal><span style='color:#1F497D'><o:p> </o:p></span></p>
<p class=MsoNormal><span style='color:#1F497D'>It seems like that the client
connects to the server via IP, the application server answers with its name and
then the client wants to use this name for further connections…. and
either it should find it in the DNS or the etc-hosts…<o:p></o:p></span></p>
