Hello, Can anyone tell me why or if https - rpc supports NTLM authentication through the ISA server I have a separate publishing rule setup for https over RPC using basic authentication all works fine. I 'm using ISA 2004 with sp1 on win03 sp1 installed. If I use the laptop on the local lan I can authenticate using NTLM fine bypassing the ISA box so it's the ISA server .
