Cannot browse created web application/site in SharePoint Services 3.0

Hi!
Cannot browse created web application/site in SharePoint Services 3.0 after creating it via Central Administration site.
My installation type is “Farm”.
Web application and Site collection (+content DB) are successfully created (“Top-Level Site Successfully Created”). I can see it in IIS: new app pool and new web site. But cannot browse it.
Maybe I need add some security access rights or smth?
If anyone have step-by-step guide – it will be great.
p.s.
when I install “stand-alone” WSPS – it creates default SharePoint-80 site in http://localhost:80/ and it works 🙂
