After install SDP Demo, can't due to logon

Hi,
 
I installed trial version on clean equipment, with Windows 2008 Standard 32-bit, IIS 7 and Sql Server 2008 R2 Standard. After installation and configuration can not use the default administrator login or guest, logon page. Can you help me in my evaluation?
 
Thanks
