Exchange 2010 DAG Issue

Hello Everyone,

I'm running into a bear of an issue that is supposed to be really simple thing to setup.  I am getting an error when trying to add the 2nd node to my Exchange 2010 DAG.  I have added the Exchange Trusted Subsystem to the Local Administrators group on my servers.  

Here's my configuration and all 3 servers are running in VMWare ESXi 4.1:
3 Servers

Server1
DAGWS - Witness server
Windows 2008 R2 Enterprise SP1
Production NIC
DAGReplication NIC

Server2
Exch1
Windows 2008 R2 Enterprise SP1
Production NIC
DAGReplication NIC

Server3
Exch2
Windows 2008 R2 Enterprise SP1
ProductionNIC
DAGReplication NIC

When I try to add the 2nd node I get this error:
An Active Manager operation failed. Error:  An error occurred while attempting a cluster operation Error:  Cluster API ""AddClusterNode() (MaxPercentage=100) failed with 0x5b4. Error:  This operation returned because the timeout period expired"" failed..

Any assistance would be greatly appreciated.

Hope all the above three servers are Exchange 2010 servers, if not the server has to be member of the "Exchange servers"(because if you plan to use DC as Witness, that will not be part of the above said group).

I have explained the DAG configuration details on the below post.

do you have any antivirus/firewall running on your nodes ? like symantec endpoint or such ? if so uninstalling them is the first thing to try

All servers are running the same version of Exchange 2010.  No Anti-Virus software installed yet and Firewalls are disabled..

They are clean individual builds, no templates.

fair enough, when it all fails exchange should point you to a .log file typically in the "C:\ExchangeSetupLogs\DagTasks\" directory

can you please attach it ?

The operation wasn't successful because an error was encountered. You may find more details in log file "C:\ExchangeSetupLogs\DagTasks\dagtask_2011-03-03_04-15-07.593_add-databaseavailabiltygroupserver.log".

I currently have IP6 deselected on both nodes.

The log file you listed is the one I uploaded.

I reenabled IPV6 on both DAGReplication and Production networks with the same result.

A point to note is that I can remove the server that is in the DAG and add the other one successfully.  I only get the error when I try to add the second server to the DAG.  I've also tried performing the add from each respective server with same results.

OK let's try something else totally disable IPv6 (not by deselecting it)

Akhater:  It is my understanding, that ipV6 is required to be available or the HubCas will stop functioning correctly and won't even install if you are starting from scratch.  I'm trying to find the article that I found when I first began tinkering with Exchange 2010 and thought I'd get rid of ipV6 because I wasn't using it and shortly there after my server stopped functioning correctly.

Akhater:  I did with the same results.  I even removed the existing member and DAG and created a new one with a never before used name and I got the same error.  I briefly mentioned this before as well, I can successfully add either one of the servers to the DAG but I only get the error when I go to add the second  server.  I've tried creating/adding from both nodes.

Are you using DHCP for the DAG members or assigning them static IP addresses?

I wound up formatting one of the servers and  the DAG Cluster configured fine.  There appeared to be some pretty bad corruption somewhere as everything was configured fine.

I wound up just formatting the system to remove any corruption.  All settings were correct but something hidden in the registry would not let it work.
