DNS related errors on Exchange
Posted on 2011-02-24
I'm running Exchange 2007 SP2 on Windows 2008 Server. We use a UNIX based DNS system.
I have a couple of Exchange clusters - SCC - Active/Active/Passive.
On each of them, within the System Log, I see the following errors:
Error - Event ID 1196 - Failover Clustering
Cluster network name resource "Network name (Exch1SCC)" failed registration of one or more associated DNS names for the following reasons:
DNS signature failed to verify"
Warning - Event ID 1119 - Failover Clustering
Cluster network name resource "Network name (Exch1SCC)" failed to register DNS name Exch1SCC.domain.com over adaptor NIC1 for the following reason
DNS Signature failed to verify"
However, the servers themselves seem to be working fine.
Can anyone shed any light?
