Hi

SBS 2011 std/Exchange 2010.

I have setup OA as below.

remote.domain.tld is also the url for RWW and to which the SBS security certificate is bound.

I can't get Outlook to connect remotely from outside the SBS domain. My Outlook setup is below;

I do get a login box so its partially working;

But the credentials fail and I get 

Under HKEY_LOCAL_MACHINE\Software\Microsoft\Rpc\Rpcproxy the key ValidPorts already had the underlined in the following. Rest was added by me. 

SBS-SERVER:593;SBS-SERVER:49152-65535;SBS-SERVER:6001-6004;SBS-SERVER.sbsdomain.local:6001-6004

I seem to be able to telnet to remote.domain.tld over ports 6001, 6002 and 6004. When I do

telnet remote.domain.tld 6001

I get;

ncacn_http/1.0

I can ping remote.domain.tld but not remote.domain.tld:6001

Where I can find what is blocking the connection?

Thanks

Regards

Hi

Figured this one out. For SBS 2011 std, as in my case, below values need to be in ValidPorts under [HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Rpc\RpcProxy];

SBS-SERVER:593;SBS-SERVER:49152-65535;SBS-SERVER:100-5000;SBS-SERVER:6001-6002;SBS-SERVER:6004;SBS-SERVER.sbs-domain.local:6001-6002;SBS-SERVER.sbs-domain.local:6004;remote.domain.tld:6001-6002;remote.domain.tld:6004;

Hope this helps.

Regards
