This Error event indicates the specified network adapter that is configured for internal DNS lookups on the Microsoft Exchange Server Hub Transport server or Edge Transport server is invalid.

To resolve this error, do one of the following:

Use the GUID of the desired network adapter as the value for the InternalDNSAdapterGUID parameter on the Set-TransportServer cmdlet. If you want to use the DNS settings of all available network adapters, enter a GUID of 00000000-0000-0000-0000-000000000000.
