RPC over HTTP problem

[Christos Kritikos]

I am running Outlook 2003 on WinXP SP1 and I am trying to
setup RPC over HTTP. I tried to follow the instructions
but the Exchange over the Internet area doesn't appear in
the connection tab for the Exchange Server. I then
followed the solution in the troubleshooting area of the
same documents (I created the registry key RPC and the
entry EnableRPCtunnelingUI). Still no luck - the option
doesn't appear. My Rpcrt4.dll meets the requirements of
article 331320 (the version of the hotfix is
5.1.2600.1142 and I have version 5.1.2600.1254). Any
other ideas? Why isn't this option available?

million thanks

If you go to this location in the registry:
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Rpc\ClientProtocols

Do you have these entries?
"ncacn_np"="rpcrt4.dll"
"ncacn_ip_tcp"="rpcrt4.dll"
"ncadg_ip_udp"="rpcrt4.dll"
"ncacn_http"="rpcrt4.dll"

Also keep in mind that RPC/HTTPs is only supported when running against an
Exchange 2003 server on Windows 2003. (All domain controllers and Global
Catalog servers must be Windows 2003 as well and properly configured.) If
you used to be on an Exchange 5.5/2000 box and the server was upgraded or
your mailbox was moved to an Exchange 2003 server, you will need to make a
new profile.

Yes I do have these entries. Also FYI the "DCOM
protocols" in the
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Rpc
reads "ncacn_http ncacn_ip_tcp". Last but not least there
is only one DC and it is a Win03/Ex03. In short
everything seems to be configured by the book. I don't
know what to assume... Does the configuration option
for "Exchange over the internet" appear ONLY if the
server supports it? What if I had created the user
mailboxes before setting up the server for PRC over HTTP?

thanks

grr... looking at step #2 of 833401 is wrong. Step #2 is done to the
Windows 2003 Global Catalog Server and not the workstation.

the only other thing i can think of is that a policy object has been applied
to hide the option. key location is
hkcu\Software\Policies\Microsoft\Office\11.0\Outlook\RPC (same key you
mentioned previously. EnableRPCtunnelingUI)

outside of that and to answer your questions... the option should show
unless a policy object hides it. (the option will become disabled against
exchange 5.5/2000). doesn't matter when you create the mailboxes (before or
after enabling rpc/https). the feature only cares that the box is winxp
(sp1) + 331320.
