What happens during the DNS validation check that Exchange Migrator does during a migration?

fact
Exchange Migrator 2.x

fact
Exchange Migrator 1.x

fix

During validation, for any Microsoft Exchange 2000 Server targets:

  1. Exchange Migrator (EM) connects to the target Exchange Server and requests the Exchange Server's DNS server value. 
    • To obtain the DNS value EM makes an LDAP call that queries the Exchange server for the property "networkAddress". 
      • This is a multivalue. 
      • The value with "ncacn_ip_tcp:" prepended indicates the DNS name of the Exchange server. If this value is not available, then the DNS validation will fail.
  2. EM will then ping the value.
    • This name will need to be ping-able from the EM console in for the migration to continue past the DNS validation portion of the migration. If the ping fails, then there is most likely a problem with DNS configuration. Please refer to Microsoft Knowledge Base for informatoin on resolving DNS name resolution issues.
