RPC over HTTP not working

Locked

Hello all:

I have a single server running server 2003 Small Business. I recently enabled Exchange and would like to use the new feature of RPC over HTTP. I think I have everything set up correctly and have gone through nearly all Microsoft info on this (knowledge base 833401, 827330, 822594). From what I can gather, my RPCPing fails with a 401 error – authentication denial. I have not set up a web server, but users are denied access to the default pages on the local small business site. Aparently, SharePoint is required, so I put myself in the same groups as users created from the server management utility, but that didn’t seem to help. Can the RPC Proxy server be on the same box as the Exchange server? Has anyone ever successfully made this work with one server?? I’ve working on this for a couple of days now. Thanks for any guidance.

Jon

You need to have IIS set up for the virtual RPC directory.

Did you also configure the ports for the RPC?

Yes, IIS has the RPC under the default web server and the properties of the RPC appear to be correct (allow plain text password – recommended by Microsoft – using SSL for security). The ports also seem to be set up correctly in the registry. They recommend deleting the contents of the RPC port info and adding NetBios and FQDN names for port 6004. There was one other entry for port 953(?) which I left there. I could try taking it out as well…

The only other thought would be that my domain name ended in .local. With the exchange server, I changed the email address for all users to .com. Is this the correct way to use .com for email domain??? Thanks again.

Well, I finally got it working – and it seems to work fairly well. We’re using Compaq tablet PC for the workstations. I basically had two problems – one was that I was inside our firewall on the local network when testing much of this. Our “firewall” is also our DSL gateway, so it just provides some basic services. On the outside, I realized that I did not have basic authentication set in Outlook setup. I had set it to NTLM or something like while testing. Once this was set back to basic, it worked fine from outside the office.

Thanks,
Jon
