Hi all. I'm trying to use automatic proxy configuration because I need to authenticate the users (I don't wanna use natACL or something else). Internet Explorer is working (I'm using a .reg file that works fine) but I can't do this work with Firefox. I've created a PAC (proxy auto config) file but it didn't work and sometimes Firefox crashes. Can anyone help me? -- Allysson Steve Mota Lacerda stevelacerda@xxxxxxxxxxxxxxxx http://www.stevelacerda.net
