Environment: Exchange 2010 on Server 2008; ADDC; also running DNS
This server is doing all Exchange roles -- it's a single server. There is another DC in the form of an old Server 2003 box, but it has nothing to do with Exchange.
Certificate is GoDaddy and appears fine.
Internal domain is abc.local; "real" domain is xzy.co.uk. Server is reffered to as mail.xyz.co.uk on the outside world and server02.abc.local internally.
Port 443 (https) is mapped over on firewall from the RIPE IP to the internal IP. The firewall is a Cisco PIX.
OWA works fine to this server from the outside world as well as interally. Internally either to https://server02.abc.local/exchange
and externally just to https://mail.xyz.co.uk/exchange
DNS is set up internally for xzy.co.uk as well.
I have been through the "Outlook Anywhere" wizard on the server with BASIC authentication; and it appeared to complete correctly.
If I ping mail.xzy.co.uk internally I get responses from internal IP 192.168.254.4 per DNS.
If I ping mail xzy.co.uk externally I get responses from correct RIPE IP per DNS.
IPv6 is deselected on the adapter settings of the single enabled network card on the server.
If I telnet to ports 6001, 6002 & 6004 internally it works and I get the correct response. The ports are blocked from the outside world, but I tested unblocking them and mapping across breifly and I got the same response -- but it didn't fix the issue so I closed them off again.
When I run the RPC over HTTP test at https://testexchangeconnectivity.com
it all works until the point:
Attempting to ping RPC endpoint 6001 (Exchange Information Store) on server mail.xyz.co.uk.
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.
Where do I go from here, please? (I have Exchange 2003 servers working fine, and it's supposed to be easy on 2010!!)
Many thanks in advance.
