Something weird happens. When I try to connect to central administration from sharepoint application server it asks me about credentials. I try to log in with farm administrator permissions, but it doesn't let me log in.
When I try to login to the central administration from a local computer or the front end web service server using the same account, I am able to login. The problem continues with my web front end server also when I try to login in one of the sites it tells me to input credentials (again sp farm admin) and it doesn't work. When I try to login to the site from a local computer or the application server using the same account, I am able to login.
I know I can access the setting using other computers, but I wonder why this happens.
