Problem in installing Openfire

Hi,

I'm new here,

The Operational System used is Windows 2003 SP2 and version of Openfire is 3.8.1,

I chose Internal database and Directory Server(LDAP)

during installation in step 1of 3(Configuration Profiles: Connection Settings) I fill all the fields, and click on the test button but nothing happens, except that the page refreshes(no message appears), and still continue with the following steps,

the step of adding an administrator returns an error(No User informed, or informed the User was not found), I believe it is because of the test was not successful.

I use firefox(21) but I tested with other browsers also and nothing changes.

Thanks!
