web problem

Hello,

I have installed opmanager 5.6 on three boxes running XP. In both cases I couldn't start the web client. No problems with ports. It seems at the tray that opmanager service is running. When I am trying to open the web page to login I get waiting response from browser (ie and firefox) and timeouts after a while. What is happening? Is there something that opmanager requires to work and not mentioned anywhere?

I have tried changing ports, disable everything else running antivirus,firewalls... I get stuck with the web client which never opens..

I would like to make it work in order to purchase a license.

Thank you
