Sharepoint site not accessible from intranet

[Rocky]

Hi guys, I have a problem that I'm really stuck with for sometime here. I have setup a Team site with some document management stuff but its just not possible to access it from the intranet, whenever I do that I get the login dialog. Enter the username/password and it asks again and after the 3rd time, the dialog goes away with only a blank (white) screen in the browser. Any help appreciated! Thanks,
