java ?

飞天二狭

Have installed IM4.1 on a win xp server. All very standard. After install I launch the app, it checks the http service and proceeds to a window telling me the name on the security certificate is invalid or does not match the name of the site. I click yes to proceed. then the java window appears with pretty much the same message if i click yes to allow the non trusted certificate a window appears titled 'hostname mismatch' hostname url is 'localhost' and the certificate is the machine fqdn. if i change the url to the fqdn then it errors with unknow url. if i click yes and proceed from the hostname error screen the browser sits with please wait. checking for java plugin. I have looked in the certificates and changed the url and am sure its something simply that i need to change. Can anyone guide me please. appreciate any help

Regards
