phpMyAdmin

I have a server with my own domain and have created some users under
htdocs/users/. I have installed phpMyAdmin under htdocs/. Everything works,
but I can't open phpMyAdmin. I have made an alias in httpd.conf:

[KOD]
Alias /phpMyAdmin/ "C:/Program/Apache2/htdocs/phpMyAdmin/"

Options Indexes MultiViews
AllowOverride None
Order allow,deny
Allow from all

[/KOD]

What is the solution?

Thanks
Susanne
