I have only one Small Business Server 2003 that is the DC and runs DNS, WINS, and Exchange. I did all the Windows and Exchange updates. It is a new installation. All is working well except one part of the Exchange: all incoming emails are shown to be stuck at the step "SMTP: Message Submitted to Categorizer".

I turned the debug level up to 7 for the Categorizer and I get the following errors in the Application log:

Categorizer received error 0x00000051 from WLDAP32!ldap_search_extW(GetPLDAP(), "", 2, "(ProxyAddresses=smtp:useer_name@any_domain.com)", rgszAttributes, ...), PLDAP = 0x083c41f0 for server server.my_doamin_name.local

Categorizer is temporarily unable to process a message.  The function 'CCfgConnection::AsyncSearch' called 'CBatchLdapConnection::AsyncSearch' which returned error code '0xc004051f' (). ( f:\tisp2\transmt\src\phatq\cat\ldapstor\cnfgmgr.cpp@2353 )

A categorization is failing over to a new connection.  The old connection was to DS host "server.myreccenter.local".  The new connection is to DS host "server.myreccenter.local".  The retry count is 1.

No outside incoming emails are delivered. All emails sent to local users are delivered fine. There are no other error messages in any other log files. Also, all outgoing emails do get delivered fine.

I searched the Internet for a solution and came out with an empty hand.
Can someone please help?
Thank you.
