SRV lookup is this correct?

Noticed some errors in netlogon

05/03 09:36:57 [CRITICAL] NetpDcGetNameIp: Sausage.empire.bob.co.uk: No data returned from DnsQuery.

Which led me to do this

Only partial servers providing internet address from this query? Is this normal or do we have a problem?

Thanks
