Exchange 2010 DAG Issue

I've been administering Exchange servers since the 4.x version so I have quite a bit of experience in dealing with them. Now, I'm completely stumped on a 2010 DAG issue that could possibly be a simple oversight but I need to get this resolved soon.  I've set up several DAGs in this same type of environment but, for some reason, this one is being stubborn.  The server is 2008 Enterprise SP2.

Problem:
I've create a DAG group (DAG3) and let it create the appropriate directory on the witness server and assigned it an IP address.  The problem is getting the initial server into the the group.  I've tried it from the EMC and also tried powershell to no avail.

Here the error returned from powershell:

A server-side database availability group administrative operation failed. Error: The operation failed with message: An
 error occurred while attempting a cluster operation. Error: Cluster API '"CreateCluster() failed with 0x5b4. Error: Th
is operation returned because the timeout period expired"' failed. [Server: exserver.foo.local]
    + CategoryInfo          : InvalidArgument: (:) [Add-DatabaseAvailabilityGroupServer], DagTaskOperationFailedExcept
   ion
    + FullyQualifiedErrorId : 667B9146,Microsoft.Exchange.Management.SystemConfigurationTasks.AddDatabaseAvailabilityG
   roupServer

Here is the error from the related DAG log:

[2010-11-16T00:16:29] The operation wasn't successful because an error was encountered. You may find more details in log file "C:\ExchangeSetupLogs\DagTasks\dagtask_2010-11-16_00-13-25.862_add-databaseavailabiltygroupserver.log".
[2010-11-16T00:16:29] WriteError! Exception = Microsoft.Exchange.Cluster.Replay.DagTaskOperationFailedException: A server-side database availability group administrative operation failed. Error: The operation failed with message: An error occurred while attempting a cluster operation. Error: Cluster API '"CreateCluster() failed with 0x5b4. Error: This operation returned because the timeout period expired"' failed. ---> Microsoft.Exchange.Cluster.Replay.AmClusterApiException: An Active Manager operation failed. Error: An error occurred while attempting a cluster operation. Error: Cluster API '"CreateCluster() failed with 0x5b4. Error: This operation returned because the timeout period expired"' failed. ---> System.ComponentModel.Win32Exception: This operation returned because the timeout period expired
   --- End of inner exception stack trace ---

I've tried this a million times today and can not get it added.  I am doing this from the server that is to be added to the group.  I've searched and read tons of related articles but none seem to fit or fix this issue.

I've done my fair share of contributing to this community in the past but now need some reciprocated help :)

firewall is disabled and I had previously reinstalled the clustering service prior to that.  IP6 is disabled.  I'll try to reinstall clustering again since I've disabled the firewall.

Well, despite having done all the suggested steps previously, I hadn't tried it in the order that just worked for me:

1) Turn off Firewall
2) Uninstall Failover Clustering
3) Reboot to finish uninstall
4) Reinstall Failover Clusting
5) Reboot
6) Add servers to DAG

Thanks for the suggestion.
