IE Stuck in blank page

I have 6 agents all with windows 2008 except one with XP in XP IE works, but in all windows 2008 IE test get blank page. I try to enable debug but the error log is not created. ¿ideas?

I updated to the last agent version, still the same problem.

If you connect to the machine and launch IE manually do you get a prompt to enable the WPT plugin at the bottom of the browser? Sometimes it has to be enabled manually. You might also check tools->manage add-ons and see if the plugins are enabled there.

Sorry Patrick, I thougt I disabled IE Enhaced security :@
once disabled all works like a charm.
