Why is that I cannot enter the Admin mode of the sample Alloy site?
I use the URL http://localhost:17000/your/relative/path/to/UI/MyEPiServerSite/Episerver , and a login page shows up.
What should be the username and password then??????
Anyone can help?
As Per writes above, you can login in with a local windows admininistrator account.
If no logins work but you have access to web.config, you could always "break in" as Fredrik describes in this blog:

Basically commenting out all the "<deny users="*" />" lines will let you log in without a password.
Quickly fix your password, then put web.config back the way it was.
Beware this should only be used in emergencies.
