Hello, I was wondering if anyone could provide me some advice (other than block IMs heh) on getting Yahoo IM to work with ISA 2004. I have found some articles on the web saying to allow port 5050, but I still seem to be having a bit of problem getting it to connect. I require authentication on my outbound HTTP rule, and I have tried setting the proxy settings manually in yahoo. I am apparently still missing something. I apologize if this has already been answered on this list I could not find it. Thanks in advance, Paul
