Jerry, Thanks I got it to work, I was trying to troubleshoot why https RPC listener would not let my outlook client authenticate using NTLM authentication. So reading one of the posts in your link helped. I changed the listener in the publishing rule to one I created that was not in use, then I deleted the listener I was using for the https over rpc applied changes and then recreated another listener and all is working again. Any idea why NTLM authentication does not work through the ISA box when my laptop is plugged into the LAN bypassing the firewall NTLM works fine, so I think is something on the isa box.
