I have a single Exchange 2007 Server Service Pack 2 running on Windows Server 2008 Service Pack 1. I have installed a UCC certificate issued by Godaddy with all the relevant alternate names including autodiscover. Port 443 is open and points to my mailserver. everything seems to be in order but I cannot configure any clients on the WAN, I have not tried from the LAN. Outlook finds the autodiscover information and starts to configure the server then I get a single logon box appearing which does not connect.
I have run https://www.testexchangeconnectivity.com
with a test account and it fails at the following step:
Testing the Name Service Provider Interface (NSPI) on the Exchange Mailbox server.
An error occurred while testing the NSPI RPC endpoint.
Attempting to ping RPC endpoint 6004 (NSPI Proxy Interface) on server MAIL-SERVER.MyDomain.offic
The attempt to ping the endpoint failed.
Tell me more about this issue and how to resolve it
The RPC_S_SERVER_UNAVAILABLE error (0x6ba) was thrown by the RPC Runtime process.
I have browsed to my external names using https and I get the expected IIS 7 screen with a valid certificate, so the certificate seems to be ok.
I beleive I have all the relevant entries in the registry shown below:
I can telnet from the server on to itself on ports 6001, 6002 and 6004.
Any ideas what I can check now?
Thanks in advance,
