Tonight I installed SP1 for Exchange 2007. Prior to completing the installation I recieved an error message about the Recieve Connectors in my Server -> Hub Transport
When the AuthMechanism parameter on a Receive connector is set to the value ExchangeServer, you must set the FQDN parameter on the Receive connector to one of the following values: the FQDN of the transport server "Xchng2k7.domain.org", the NetBIOS name of the transport server "XCHNG2K7", or $null.
Our internal domain name is different then our external domain name. Internal = .org / External = .com
Our Recieve Connector's FQDN was ( prior to installing SP1 ) webmail.domain.com. This was needed due to it being the url for our SSL cert and the requirements for AutoDiscovery.
When I recieved the error, I looked around for a while for an answer, but when I couldn't find one, I decided to just go ahead and change the FQDN to Xchng2k7.domain.org and figured once SP1 completed successfully, I could then go back and change it to what it was, webmail.domain.com. Well, I was wrong! If I try to change it back, I get the same error message.
How can I resolve this?
