You can't prevent admin actions in their own domains. Are you authenticating outbound traffic? Has he configured the ISA to provide a single set of credentials in the upstream request?

One of the users, who is an administrator in a different domain(my domain and his are not authenticated, they are just physically connected) has configured his own ISA server and gave access to many users in his domain using my ISA server to upstream all internet requests. My question is: Is there any configuration in my ISA server that I have to change to prevent such action? ------------------------------------------------------ List Archives: http://www.webelists.com/cgi/lyris.pl?enter=isalist ISA Server Newsletter: http://www.isaserver.org/pages/newsletter.asp ISA Server FAQ: http://www.isaserver.org/pages/larticle.asp?type=FAQ ------------------------------------------------------ Other Internet Software Marketing Sites: Leading Network Software Directory: http://www.serverfiles.com No.1 Exchange Server Resource Site: http://www.msexchange.org Windows Security Resource Site: http://www.windowsecurity.com/ Network Security Library: http://www.secinf.net/ Windows 2000/NT Fax Solutions: http://www.ntfaxfaq.com ------------------------------------------------------ You are currently subscribed to this ISAserver.org Discussion List as: jim@xxxxxxxxxxxx To unsubscribe send a blank email to $subst('Email.Unsub')
