I got solution through GPO setting, so please ignore this mail! ----- Original Message ----- From: Roy Tsao To: isalist@xxxxxxxxxxxxx Sent: Monday, October 09, 2006 1:54 PM Subject: Re: [isalist] Re: How to Deploy (Upgrade) ISA 2006 Firewall Client on top of ISA 2004 Firewall Client by Group Policy Hi Jim, I have this KB in hand already. Actually, I am considering to migrate ISA2K4 into ISA2K6, the main concern for me right now is how to deploy new Firewall client program by GPO. I have one group policy applied to OU to deploy ISA2K4 Firewall Client, and then is that no problem to addup one more policy to achieve in-place client update or is any solution in the scenario?
