I have this irretating issue that i just can not get fixed. this is the setup we have at our office:
SBS 2003 Prem, ISA 2004, DC, GC. all this is on one server.
the layout is as follow:
----WAN----- netgear router ----- ISA server ------- Local Area Network
the router is configure with an IP of 192.168.200.x and it forwards requests to the ISA server which has 2 Nics
external nic is 192.168.200.x and another nic which is connected to the LAN.
My service pack Levels are the following:
ISA 2004 SP1 & 2
SBS 2003 SP1
Here are some answers to questions you might ask:
1 i have configured my Exchange server as a Back-end server.
2 configured CA on DC, CA and certificate matches the name of the website, Server and Client trusts the
certificate, both imported into the Trusted root authentication...
3 i configured the IIS virtual directory (RPC) to use ONLY basic authentication
4 Allowed RPC traffic from the internal network to the Localhost
5 configured the client computer, client uses Office 2003.
6 when i type the url: https://mail.mydomain.co.za/rpc
i get the logon box and i then get that access denied
ACL error. which i should get.
7 when i type the url: https://mail.mydomain.co.za/rpc/rpcproxy.dll
i get the blank page with the little lock in the
right hand corner of internet explorer. that works.
8 when i use the client computer internally (On local network) and i connect via HTTP over RPC i get the successful
HTTPS connection when i run outlook.exe /rpcdiag.
9 I created a web publishing rule to publish the RPC over HTTP site described in the following link:
10 I have allowed inbound and outbound RPC port 135 traffic on the ISA server and Router.
11 I have configured the neccesary registry entries, ValidPorts. entreis are as follow:
12 here are a few links i used for troubleshooting and further reading:
I know that the issue has to be with the ISA firewall!? i have tried changing the HTTP filter on the web publishing
rule to only allow RPC_IN_DATA and OUT.
if possible could some please assist me in how to (In depth) publish RPC over HTTP/s in ISA server 2004
