Hi, I know this will be a hard question to answer but I will give it a try anyway. I can download files from the ISA server at speeds of up to 16kbps. But from a PC on the LAN the speed drops to 3kbps. The conditions on the ISA Server are the same. Same number of users. Most are only using for email and only a little of that is coming through. Both ISA server and other PC are set up as proxy clients. I followed Jim's article on how to configure the interfaces. I don't know where to start looking. TIA Nathan Simpson
