Greetings, community!
We have next Exchange configuration:
Exchange Server 2007 (With last RU) on Windows Server 2008R2. All roles, except Edge, are on this server.
So, we have published OWA, ActiveSync successfully through ISA Server 2004. Testconnectivity tells us that all is correct and it's true)
But we have strange problem with RPC over HTTPS:
Testconnectivity tells us: RPC 6004 (NSPI Proxy Interface) and RPC_S_SERVER_UNAVAILABLE (0x6ba) in the details.
We have already use all receipts from http://blogs.technet.com/b/exchange/archive/2008/06/20/3405633.aspx and http://www.tech-archive.net/Archive/Exchange/microsoft.public.exchange.setup/2004-07/1151.html articles.
Enabling expert auditing of NSPI Proxy on Exchange server shows warning when Testconnectivity try to connect:
NSPI Proxy listener thread (ID: 0xfec) could not connect to the server on transport . The winsock subsystem returned error code:[0xRpc/HTTP].
RPCPING utility tells us:
Exception 1722 (0x000006BA)

Out DC controllers are listening 6004 port. And Exchange server successfully connect with DC with information message:
NSPI Proxy successfully connected to the NSPI Service on server DC.FQDN.NAME at endpoint 6004 on RPC protocol sequence ncacn_http.
Additional information:
Outlook 2003/2007/2010 can't connect to our Exchange through RPC/HTTPS. But Outlook 2013 do it without any problems!
I don't know where I can continue to dig)
