Hello All, I have two questions and I need your help and advice. 1. I am not able to ping the external NIC on the ISA Server, The problem is I was able to do so. I don't know what happen, all I changed is applying the Blaster Worm Patch and the Protocol Rule from ISA tools site. 2. How can I know the actual amount used by the ISA cache, In the setup I choose for example 5 GB for the cache and ISA created one file with the whole amount, I believe its not all used, I need to know what is actually used. Please advice and help. Thanks and have a nice day, Ahmed
