Hi all I've got a weird one for you. Isa Enterprise. Works absolutely brilliantly apart from one small detail which has me beat. I can connect to ftp sites from one w2k pro workstation. I can't connect from any other workstations or even the ISA server itself. All the workstations are proxy clients, all set up exactly the same. The servers are nat clients. DNS resolves no problem. I can ping anywhere no prob. If I try to connect from any workstation other than the one that can connect with I get my own ftp site. Any ideas?
