From: Shem Sargent on
I used https://www.testexchangeconnectivity.com/ and received the
error report following this message (failure towards the bottom). Any
ideas what I configured incorrectly on SBS 2003 SP2, Dell PowerEdge,
to get this error?

Already followed http://technet.microsoft.com/en-us/exchange/bb123622(EXCHG.65).aspx
and checked http://technet.microsoft.com/en-us/exchange/bb124175(EXCHG.65).aspx.

Thanks in advance,
Shem Sargent
