Outlook RPC via http

[bigdog1175]

I have a new SBS 2003 R2 setup and running behind a Cisco Pix on the DMZ. I have ports 80,443,25 open on the firewall. I can access and full functionality of OWA from anywhere, I have full Outlook functionality on the inside of the firewall but when I try to connect using Outlook from outside the firewall the password window keeps popping up requesting a username and pass I have tried domain\username, full username, alias and it does not connect and keeps asking for a password. I have followed the well documented steps for setting up Outlook and RPC/http for both client and server what am I missing and thoughts are appreciated .

What are you getting when you run Outlook with the /RPCDIAG switch?

Its because of the rpc security on the server. Go into IIS Management and into default wesite, right-click RPC and choose properties. Under directory security you need to take the tick out of basic and tick integrated.

Then on the client go through the account settings, more settings option. First go to security tab and make sure it says ntlm at the bottom. Then go to connection tab an go to rpc over http settings and make sure it is ntlm at the bottom
