Hi Everyone! Can you please help me what is the best way to configure these apps on ISA2K4? I need to block them and allow only specified users to have access on them. Problem is if I allow HTTPS, you can still connect thru these apps. Although I already specified ports and sites that these applications connects to. Do you have any idea what are the right ports/sites to be specified on ISA2K4? Many thanks! mike DISCLAIMER: This Message may contain confidential information intended only for the use of the addressee named above.
