After changing the domain that the server belongs to, you receive:
Event Source: NETLOGON
Event Category: None
Event ID: 5781
The problem is due to old entries in the DNS zone of the previous domain, probably due to a deregistration failure.
Search for the Netlogon.dns file in a sub-folder of the %SystemRoot% folder. Look for lines that begin with a semicolon, like ;5175a911-d70b-4d3c-8df1-024ca6cd6a50._msdcs.company.net. 600 IN CNAME server.child-domain.company.net, and remove the stale records. Then stop and resatart the Netlogon service.
