@Sadda:

If you can bring the cluster core resources online then this is not your issue. This issue would prevent you from manually brining the cluster core resources online.

I would suggest reviewing the application and system logs for events regarding the cluster core resources.

@Tim,

We're still encountering this problem numerous times in SP2 with Update Rollup 4. We've to manually bring the cluster online!

@mfahey

Assuming you actually have this issue if you followed the workaround then you should have been fine. Take a look at my collapsing DAG networks blog post as this could be another reason your cluster networks are not maintained correctly.

The solutions above do not work. I do not have SP1 installed yet.

When bringing the IP ADDRESS online I get error code: 0x80071737

When bringing the dag name online I get: Error code: 0x80071736 The resource failed to com online due to the filure of one or more provider resources.

Any other fixes for this?

I had the same experience as @MattP_75, I had to change the role in registry: http://lokna.no/?p=998

I have a two node Exchange SP1 DAG, and have just noticed this error. My two servers are clean Exchange SP1 installs.

Whilst all appears to be OK with the DAG, seeing the "resource offline" error in the Failover Cluster Manager is a little disconcerting.

I attempted to amend the settings for "Cluster Network 2" and check the “Allow clients to connect through this network” box but each time I apply the setting and then go back into the netowrk properties, the box is unticked again.

The powershell and cluster.exe commands didn't work for me either.

I have managed to bring the cluster online however, by manually changing the "Role"=dword:00000001 in the registry (as described above) to "Role"=dword:00000003.

After doing this, I have managed to bring the resource online successfully.

@GAZ

Are you sure your issue is not fixed by SP1. We have had no reported cases of any issues post SP1 when the instructions are followed. As a reminder, if you had the issue pre-SP1 SP1 alone does not fix the issue, the workaround must be followed. The issue is simply prevented from re-occuring.

Also - just becuase you have a resource offline does not mean you have this issue - there are multiple reasons a resource maybe reporting offline.

So, again, another issue that is meant to be fixed by SP1, isnt.......................

Currently I have a DAG member that is reporting as offline, failed......

Dont msft test anything anymore?????

I have run the fix a number of times after installing SP1 for Exchange 2010 and one of my two DAG addresses are reporting as offline. Is there any other fix available?

If the issue existed prior to upgrading then you will have to follow the workaround. SP1 will prevent the issue from reoccuring.
