Well I think its playing a role in the RPC over HTTP because here at my home office I was able to get RPC over HTTP working which uses a standardize domain (domain.com) though I had to use the external IP of the ISA server (NIC) because I was trying to go out my router and back in which always work. :) As soon as I set my Host file to be the external IP of my ISA box (10.10.10.2) I was able to login as whoever I wanted. At this companies site their internet IP is assigned to their external NIC on ISA; the company that provides them DSL up sold them to use crappy Netophia routers so they could better utilize their 4 extra IP's. So the connection goes from the Netophia router to the ISA box and is wide open (nothing is being blocked). Anyhow both my machine and the companies one are setup identically with the exception they have their own cert and I have my own cert. I am able to get connected to mine theirs won't connect. I do have a question: is there anyway for an ISP to block RPC over HTTP? I know most ISP's today block port 135 on the edge of their firewalls, thus most DSL customers end up with no port 135 traffic. Or does RPC over HTTP only use 443 or 445, and port 80?

We are installing SP1 as I type this message and will test it again, but can I be sure that its related to not having SP1? We have the client machine connected to a DSL modem in the same office but non of the traffic goes through the server, it all goes out to over the internet back into the office.

Any "real" RPC traffic you see is a result of client misconfiguration. What is the client you're using (OS/SP/Office ver / patches)? Where is the client operating from; internal or external to ISA? ------------------------------------------------------- Jim Harrison MCP(NT4, W2K), A+, Network+, PCG http://isaserver.org/Jim_Harrison/ <http://isaserver.org/Jim_Harrison/> http://isatools.org <http://isatools.org/> Read the help / books / articles! ------------------------------------------------------- ________________________________ From: Andrew English [mailto:andrew@xxxxxxxxxxxxxxxxxxxxxx] Sent: Tuesday, February 22, 2005 13:14 To: [ISAserver.org Discussion List] Subject: RPC over HTTP problems Hi, I have setup RPC over HTTP along with OWA using Tom's Exchange / ISA info. Though I don't think there is any problem with his material I am having a problem wirh RPC. The OWA with SSL works flawlessly. When I setup the log in ISA to only look at the machine that we are using on the external side to connect to RPC over HTTP its able to negoicate with HTTPS on 443 without any problems but the RPC (all interfaces) id denied access by the default rule. I am wondering is there something else I need to set on ISA to enable the RPC protocol to work?
