Is the ISA part of your domain or have you allowed it to use RADIUS to authenticate domain users? -----Original Message----- From: Rajnish Malik [mailto:rajnish@xxxxxxxxxxxx] Sent: Saturday, March 05, 2005 8:44 PM To: [ISAserver.org Discussion List] Subject: [isalist] Authentication Problem in ISA 2004 Importance: High http://www.ISAserver.org Hi All, I have an ISA 2004 connected via an ADSL Router. I have intermittent problem of ISA 2004 prompting for Username and password for Web Proxy client request. I have configured Integrated Windows only. I have not selected "ask for user credentials..." Problem when ISA is asking for Authentication it does not accept the username of my domain users, whereas if I provide administrator username and password it immediately authenticates and allows internet access. This is strange problem I have many such installations at my client places but no one has this kind of issue. I have revised the system policy and Access policy. It looks that there are no conflicts. Any ideas?
