website not available

Hi,

I am new with this forum and with the stuff. The problem is as follows:

I am running IIS6 under SBS2003 on a HP server. With Visual Web Developer 2010 I created 2 websites in 

inetpub/wwwroot. and created these 2 websites in IIS6.

Default page is Default.aspx. Result: webpages not available from the internet

Then I created in inetpub/wwwroot a testfolder with index.htm and created a testsite in IIS with the same

data in the Properties as the 2 VWD2010-websites.

Result: Testwebsite is perfectly shown from the internet.

Has anyone an idea  what I am doing wrong ?
