Hi James,

Thanks for the quick reply.

Yep, worked great! Fixed all of those replPropertyMetaData errors! :-)

Date & time matches. But the fact that the same identical message is 
logged multiple times per second, without an end seems a bit strange... 
Combined with high cpu usage on the DC where this happens. (yesterday 
DC2, currently on DC4)

There is no DC1 mentioned anywhere there. And the two errors remain:

I was asked a question during the samba-tool dbcheck:

> Add yourself to the replica locations for DC=DomainDnsZones,DC=samba,DC=company,DC=com? [y/N/all/none] N
> Not fixing missing/incorrect attributes on DC=DomainDnsZones,DC=samba,DC=company,DC=com

Should I answer Yes to those two questions?
