Hi,<BR><BR>I'm having security problems with all my ASP.NET apps. Whenever I try to view an aspx page, even a simple "Hello world" page, I get "Server Application unavailable" response with an Administrator note to check the event log. This contains loads of messages saying that aspnet_wp.exe could not be launched because the user/password supplied innthe processModel section of the config file are invalid.<BR><BR>Well I've checked both web.config and machine.config, where the authentication is set to "Windows" and authorisation is set to allow all users (users=*). The web.config didn't contain any authentication or authorisation sections so I guess these are inherited from machine.config? I tried copying the commented-out processModel section from machine.config to web.config, uncommenting it and then supplying valid username and password attributes, but to no avail.<BR><BR>Can anyone help?<BR><BR>TIA<BR><BR>JohnMight want to try here.............<BR><BR>http://support.microsoft.com/search/preview.aspx?scid=kb;en-us;Q315158Looks like the info I'm after<BR><BR>Thanks
