Windows 2008 R2 installing Exchnage 2010

I'm installing fresh exchange 2010 for new site running on image Windows 2008R2.

when you install exchange 2010 on Windows 2008R2, does it automatically install Failover Clustering ?

my current issue right now is, after install Exchange 2010 with SP3, the Failover cluster wasn't install and I thought exchange installation would taking care if this. now I have to manually install Failover cluster but the service won't start.

What should I do to get the cluster service to start ? I did reboot so many time. i did try to uninstall it but the error said
" This server is an active node in a failover cluster" uninstalling the failover cluster feature on this node may impact the availability of cluster services and application" recommended that you evicted the server from cluster membership. "

so this is fresh exchange server installation in new site, so what do i need to do to bring up the services ?

First you need windows enterprise edition OS for clustering feature. Next, for setting up HA, you need more than one server. I advise you to read this KB:

thanks for sharing this article..

question, does the exchange 2010 installation supposedly be installing failover cluster or we need to perform that separately ?
I don't recall I ever have to install failover cluster. I thought exchange does that during install.. that is what I would like to confirm ?

I will go over the KB .. thanks

You don't need to install anything separately. Exchange will do it automatically.

ok.. that is how I remember it.. I don't remember I ever had to install failover cluster.. what situation during exchange 2010 installation didn't install the failover cluster ?

can I reinstall the exchange so I make sure cluster service is install or by me manually install cluster is that ok ?
Todd NelsonSystems EngineerCommented:
Like Amit stated, with Windows 2008 R2 the OS version must be Enterprise.  Additionally, Exchange 2010 will not install failover clustering.  In fact, creating a DAG won't install failover clustering.  Failover clustering will not install until you add an Exchange server as a member of a DAG--which will be done automatically, provided you have an Enterprise version of Windows 2008 R2.

On a side note, why Exchange 2010 and not 2013 or 2016?
AmitIT ArchitectCommented:
No need to install Exchange or anything else. First you share, what is OS version.
Jimmy WangAuthor Commented:
we moving our datacenter and we need to replicate our exchange 2010 on that site and let the DAG database replicate there, then we will start planning exchange 2016.. right now we doing data center moves.

so it is ok with reinstall the exchange installation to get the failover cluster in good state or do I need to uninstall exchange first ?

So, OS wise you are good. Now you need to install one more Exchange server, if you want to setup the HA. Follow the article, I gave you above and you will be able to set the HA for Mailbox role. However, I advise you to do more reading on setting up Exchange HA. As it is requires lot of planning and testing, before you push into prod. If you have option to hire an IT Architect for Messaging. Take the help from Messaging Architect.

for the HA configuration, we doing that later.. right now, I'm just installing exchange binary first and we will start configuring database and DAG member.

at current time, I just got finish installing exchange 2010 on Windows 2008R2 server and notice that failover cluster wasn't install.. so I was wondering if the install gone bad or why it didn't install failover cluster.  But I did went ahead to add features installing failover cluster and the service wouldn't' start.

so I though the service should have start anyways with I have to go the point of conjuring cluster.. is that correct service should able to start ?
AmitIT ArchitectCommented:
As I said,  you don't need to install failover cluster now. The time you are going to setup the DAG, that time, it will be installed and configured automatically.
Jimmy WangAuthor Commented:
this helped me answer my question. so basically I jumped ahead by installing.. we not there yet to configure the DAG yet.. we just at the point for binary installation.

"The time you are going to setup the DAG, that time, it will be installed and configured automatically. "

thanks for clarifying that..
