Unable to add server to exchange 2010 DAG
Asked by: HFK-IKTSolved by: Netminder
I am about to jump off the roof because of a Exchange 2010 DAG-problem.
I have a 3 fresh installed Windows 2012 Servers with Exchange 2010 SP3.
I am trying to add the first server to my DAG but this operation fails with the following message:
A database availability group administrative operation failed. Error: The operation failed. CreateCluster errors may result from incorrectly configured static addresses. Error: Computer account 'dag' couldn't be validated by user 'NT AUTHORITY\SYSTEM'.
Error: Unknown error (0xc000005e) [Server: DAG1.xxx.xx]
+ CategoryInfo : InvalidArgument: (:) [Add-DatabaseAvailabilityG
+ FullyQualifiedErrorId : 974D64A6,Microsoft.Exchang
+ PSComputerName : dag1.xxx.xx
I have two network interfaces on the servers and I am not able to see anything wrong with these.
Since Exchange is installed on 2012 servers i have pre-staged the CNO and tried to give both Exchange Trusted Subsystem and the first node (dag1) full access to the object. I also tried to add a DNS-record for the CNO.
I have attached the logfile from Dagtasks.
Hope you can assist me in this annoying problem. :-)
