Cannot configure the Locale module after installation

I am unable to configure the Locale module after a successful installation of the module.

The installation followed these steps:

1. Installed Drupal in English (no extra languages). (A number of other modules are installed.)
2. drupal-7.13.da.po exists in \\webroot\profiles\standard\translations
3. On the module page, enable Locale.
4. On the module page, click Configure for the Locale module.

5. Result: "Server not found" error page.

Same error for Translate interface
>> http://www.example.com/admin/config/regional/translate

Failure seen in Firefox 13 and Internet Explorer 9.

How can I debug this issue?
Please advice. Thanks.
