Hi everybody, Whether it works? [subj] If i use Basic authentication in properties web listner for "rpc over http" firewall allow rule, remote clients can`t access to RPC Proxy behind ISA 2004. If i use "forms-based" authentication in properties for the same rules, remote clients get access to RPC proxy. But then i can`t use "forms-based" for my Exchange Server. How can i use basic authentication for publishing RPC over HTTP in ISA2004? Yours faithfully, Andy
