Outlook Anywhere - SBS 2011

Hello,

We have a SBS 2011 server, and Outlook anywhere is turned on.  We cannot get our Outlook clients to connect.  I used the Microsoft REmote Connectivity Analyzer, and everything passes until this step:

Attempting to ping RPC endpoint 6001 (Exchange Information Store) on server mail.********.com.
       The attempt to ping the endpoint failed.
        Tell me more about this issue and how to resolve it
       
      Additional Details
       The RPC_S_SERVER_UNAVAILABLE error (0x6ba) was thrown by the RPC Runtime process.

Any suggestions on what we need to do to get this work.  This is stock SBS 2011 install,
nothing has been modified.  Exchange itself, along with OWA, Activesync, works fine.

Thanks

We cannot get our Outlook clients to connect.
>> Are these outlook clients connecting locally or remotely.

did you configure the exchange server or you are still setting it up ?
Was it working earlier ?

Sorry, should have made that clearer:

Local clients are fine, it's the remote clients that cannot connect.  (These clients have never connected, so we cannot get them setup initially).

This server has been in production about 1 month.  Internally, everything is fine.  We now need to setup a remote PC, and cannot.  We used the Microsoft Remote Connectivity Analyzer, and found the error there, as Outlook wasn't telling us specifically what was wrong.

- Browse url https://mail.yourdaomin.com/rpc/rpcproxy.dll extenally post what you are getting.

- Browse url https://localhost/rpc/rpcproxy.dll locally and post what you get.

In each case, I am prompted for a username and password.  Once I enter the username and password, the login box disappears and I am presented with a white page.  It appears to have accepted my login.  What does this mean?

- It proves that rpcporxy.dll is getting authenticated properly.

- Make the following changes in the system32\drivers\etc\hosts file:

Comment out the line ":::1    localhost"

Add the following two lines:

   <IPv4 address>    <hostname of the computer>

   <IPv4 address>    <FQDN of the computer>

- Go to command prompt run below commands:
ipconfig /flushdns
ipconfig /registerdns

- then IISReset to restart IIS.

- Above changes perfom testexchangeconnectivty test.

Thanks for the info, I tried exactly as you described and still the exact same error.  The only thing I could not do is comment out the line, as it was already commented out.  I do not believe anyone commented this out before now, as I have not, and the server is a fresh install.  None the less, adding those lines did not make any difference.

What shreedhar suggested is excellent !
I would just add the following, if the above steps does not help
Run in CMD
>nestat -anob
check proceess (PID) that are using ports 6001, 6002 and 6004

Also reinstalling the RPC over HTTP component of IIS might help.
Before reinstalling disable Ooutlook Anywhere from EMC , then enable it again
