I have just installed the DNN Platform. It visited me with this error and I cant login to start anything

The resource cannot be found.

Description: HTTP 404. The resource you are looking for (or one of its dependencies) could have been removed, had its name changed, or is temporarily unavailable. Please review the following URL and make sure that it is spelled correctly.

Requested URL: /Login.aspx

I used the default database in the installation

Any assistance?
