Hello Nick,
Thank you for posting here!
According to your description, I understand this issue to be as follows:
You are unable to use RPC over HTTP to connect to the Exchange Server. When
running RPCPing, you get the "Error 12029 returned in the
WinHttpSendRequest".
If I have misunderstood your concern, please let me know.
Based on my experience, this issue may be caused by 443 ports blocked or
other potential factors. Please perform the steps below to narrow down the
problem.
1. Firstly, please double confirm that the mailbox you try to access via
RPC over HTTP hosts in the Exchange 2003 Server. Based on my knowledge, the
issue is not related to whether Exchange Server is also DC.
2. Double confirm that you have configured the RPC proxy server to use the
default ports for RPC over HTTP that are specified inside the corporate
network.
(1) On the RPC proxy server, start Registry Editor.
(2) Locate and then click the following registry subkey:
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Rpc\RpcProxy
(3) In the right pane, right-click "ValidPorts", and then click "Modify".
(4) Remove all the information from the "Value data" box, and then type the
following information:
<ServerNETBIOSName>:6001-6002;<ServerFQDN>:6001-6002;<ServerNetBIOSName>:600
4;<ServerFQDN>:6004
(5) Click "OK", and then quit Registry Editor.
For more detailed information, please refer to the following Knowledge Base
article:
833401 How to configure RPC over HTTP on a single server in Exchange Server
2003
http://support.microsoft.com/?id=833401
3. Please check whether you can access OWA via
https://exchangeserver/exchange/. We can also use the PortQueryUI tool to
test whether the issue is related to RPC connection or port problems.
The PortQueryUI tool is available for download from the following Microsoft
Web site:
http://download.microsoft.com/download/3/f/4/3f4c6a54-65f0-4164-bdec-a3411ba
24d3a/PortQryUI.exe
Then, you can use the Port Query tool to query your Exchange Server and
double check whether 80 and 443 ports respond as "NOT LISTENING". For more
detailed information about the Port Query tool, please refer to the
following Knowledge Base article.
310298 How to Use Portqry.exe to Troubleshoot Microsoft Exchange Server
http://support.microsoft.com/?id=310298
4. Finally, please double check whether the user is able to access mailbox
in the internal network in Outlook. You can also perform the RPCPing test
in the internal work too.
Please don't hesitate to let me know in case you have any further updates
or concern.
Have a nice day!
Regards,
Martin Qiu
