Guest login

What is the "permissions screen"?

it is the screen where you add security data

I need to send a screenshot that explains what you mean to support team.

Is it possible to have an application to have a guest login without going to the permissions screen?

Correct me if I'm wrong...
Do you mean that you want your application to, by default, display the LIST page so that guest or any user can see/browse the records immediately (like this forum page) rather than the LOGIN page? Only until a user is authenticated that they can add or edit records.
Are you trying to accomplish a forum site?

you are correct in your assumption. but no, i am not trying to accoplish a forum site.
in my organization they use a database to store documents on the intranet share, and every one has to be able to search for a particular document and being able to download and retrieve it.

there is only 1 person who can update links and add documents to the database.

in our organization they are very bad in password remembering and paniking when someting is even asking them for a password.

Have you tried modifying the index.html file by changing the URL=login.asp into url=yourappname_list.asp
This is the portion that I can see that you can bypass the login.asp and go directly to the application's list page.
