[K.C. Chan]

All,
does anyone know what this errors mean:

Jul 8 09:29:26 host-xyz named[10094]: dynamic update failed: 'RRset exists (value d
ependent)' prerequisite not satisfied (NXRRSET)
Jul 8 09:29:26 host-xyz named[10094]: client 151.201.21.48#3589: update denied
Jul 8 10:29:30 host-xyz named[10094]: dynamic update failed: 'RRset exists (value d
ependent)' prerequisite not satisfied (NXRRSET)
Jul 8 10:29:33 host-xyz named[10094]: client 151.201.21.48#3604: update denied

Thanks.

Hi,

This message means that a dynamic update request failed because a prerequisite condition - that some name or group of names
(RRset in DNS jargon) existed - did not hold. An NXRRSET error - no
such RRset - was returned to the client making the request.

Some clients try to register themselves in DNS by default. Win2K clients, for
example.

Hope this helps
